Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Asthma research studies

Specifically within medical research, studies on asthma often employ case studies to explore the individual and environmental factors that influence asthma development, management, and outcomes. A case study can provide rich, detailed data about individual patients' experiences, from the triggers and symptoms they experience to the effectiveness of various management strategies. This can be crucial for developing patient-centered asthma care approaches.

Other fields

Apart from the fields mentioned, case studies are also extensively used in business and management research, education research, and political sciences, among many others. They provide an opportunity to delve into the intricacies of real-world situations, allowing for a comprehensive understanding of various phenomena.

Case studies, with their depth and contextual focus, offer unique insights across these varied fields. They allow researchers to illuminate the complexities of real-life situations, contributing to both theory and practice.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Conducting a case study involves several steps, from defining the research question and selecting the case to collecting and analyzing data . This section outlines these key stages, providing a practical guide on how to conduct case study research.

Defining the research question

The first step in case study research is defining a clear, focused research question. This question should guide the entire research process, from case selection to analysis. It's crucial to ensure that the research question is suitable for a case study approach. Typically, such questions are exploratory or descriptive in nature and focus on understanding a phenomenon within its real-life context.

Selecting and defining the case

The selection of the case should be based on the research question and the objectives of the study. It involves choosing a unique example or a set of examples that provide rich, in-depth data about the phenomenon under investigation. After selecting the case, it's crucial to define it clearly, setting the boundaries of the case, including the time period and the specific context.

Previous research can help guide the case study design. When considering a case study, an example of a case could be taken from previous case study research and used to define cases in a new research inquiry. Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question. This involves selecting appropriate methods of collecting data, properly training interviewers or observers, and systematically recording and storing the data. It also includes considering ethical issues related to collecting and handling data, such as obtaining informed consent and ensuring the privacy and confidentiality of the participants.

Data analysis

Analyzing case study research involves making sense of the rich, detailed data to answer the research question. This process can be challenging due to the volume and complexity of case study data. However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Understanding the strengths and limitations of case study research can also guide researchers in deciding whether this approach is suitable for their research question . This section outlines some of the key strengths and limitations of case study research.

Benefits include the following:

• Rich, detailed data: One of the main strengths of case study research is that it can generate rich, detailed data about the case. This can provide a deep understanding of the case and its context, which can be valuable in exploring complex phenomena.
• Flexibility: Case study research is flexible in terms of design , data collection , and analysis . A sufficient degree of flexibility allows the researcher to adapt the study according to the case and the emerging findings.
• Real-world context: Case study research involves studying the case in its real-world context, which can provide valuable insights into the interplay between the case and its context.
• Multiple sources of evidence: Case study research often involves collecting data from multiple sources , which can enhance the robustness and validity of the findings.

On the other hand, researchers should consider the following limitations:

• Generalizability: A common criticism of case study research is that its findings might not be generalizable to other cases due to the specificity and uniqueness of each case.
• Time and resource intensive: Case study research can be time and resource intensive due to the depth of the investigation and the amount of collected data.
• Complexity of analysis: The rich, detailed data generated in case study research can make analyzing the data challenging.
• Subjectivity: Given the nature of case study research, there may be a higher degree of subjectivity in interpreting the data , so researchers need to reflect on this and transparently convey to audiences how the research was conducted.

It is a qualitative research approach that aims to provide a detailed and comprehensive understanding of the case being studied. Case studies typically involve multiple sources of data, including interviews, observations, documents, and artifacts, which are analyzed using various techniques, such as content analysis, thematic analysis, and grounded theory. The findings of a case study are often used to develop theories, inform policy or practice, or generate new research questions.

Types of Case Study

Types and Methods of Case Study are as follows:

Single-Case Study

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail.

For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific organization to explore their management practices. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a single-case study are often used to generate new research questions, develop theories, or inform policy or practice.

Multiple-Case Study

A multiple-case study involves the analysis of several cases that are similar in nature. This type of case study is useful when the researcher wants to identify similarities and differences between the cases.

For Example, a researcher might conduct a multiple-case study on several companies to explore the factors that contribute to their success or failure. The researcher collects data from each case, compares and contrasts the findings, and uses various techniques to analyze the data, such as comparative analysis or pattern-matching. The findings of a multiple-case study can be used to develop theories, inform policy or practice, or generate new research questions.

Exploratory Case Study

An exploratory case study is used to explore a new or understudied phenomenon. This type of case study is useful when the researcher wants to generate hypotheses or theories about the phenomenon.

For Example, a researcher might conduct an exploratory case study on a new technology to understand its potential impact on society. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as grounded theory or content analysis. The findings of an exploratory case study can be used to generate new research questions, develop theories, or inform policy or practice.

Descriptive Case Study

A descriptive case study is used to describe a particular phenomenon in detail. This type of case study is useful when the researcher wants to provide a comprehensive account of the phenomenon.

For Example, a researcher might conduct a descriptive case study on a particular community to understand its social and economic characteristics. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of a descriptive case study can be used to inform policy or practice or generate new research questions.

Instrumental Case Study

An instrumental case study is used to understand a particular phenomenon that is instrumental in achieving a particular goal. This type of case study is useful when the researcher wants to understand the role of the phenomenon in achieving the goal.

For Example, a researcher might conduct an instrumental case study on a particular policy to understand its impact on achieving a particular goal, such as reducing poverty. The researcher collects data from multiple sources, such as interviews, observations, and documents, and uses various techniques to analyze the data, such as content analysis or thematic analysis. The findings of an instrumental case study can be used to inform policy or practice or generate new research questions.

Case Study Data Collection Methods

Here are some common data collection methods for case studies:

Interviews involve asking questions to individuals who have knowledge or experience relevant to the case study. Interviews can be structured (where the same questions are asked to all participants) or unstructured (where the interviewer follows up on the responses with further questions). Interviews can be conducted in person, over the phone, or through video conferencing.

Observations

Observations involve watching and recording the behavior and activities of individuals or groups relevant to the case study. Observations can be participant (where the researcher actively participates in the activities) or non-participant (where the researcher observes from a distance). Observations can be recorded using notes, audio or video recordings, or photographs.

Documents can be used as a source of information for case studies. Documents can include reports, memos, emails, letters, and other written materials related to the case study. Documents can be collected from the case study participants or from public sources.

Surveys involve asking a set of questions to a sample of individuals relevant to the case study. Surveys can be administered in person, over the phone, through mail or email, or online. Surveys can be used to gather information on attitudes, opinions, or behaviors related to the case study.

Artifacts are physical objects relevant to the case study. Artifacts can include tools, equipment, products, or other objects that provide insights into the case study phenomenon.

"A concise and readable primer for doing case study research, the fruit of many years of experience and wisdom. Robert E. Stake's book is also valuable as a genuine attempt to integrate, rather than pick arguments with, the best there is of contending approaches to qualitative inquiry."

--A. Michael Huberman, Harvard University and The Network, Inc.

" The Art of Case Study Research is most useful to novices in qualitative inquiry. I could see using it in combination with other texts or readings in an introductory course to qualitative research methods or in a research methods survey course. Because of its readable style and wellspring of examples and helpful suggestions, both graduate and undergraduate students will find the book useful. Researchers seeking to more fully understand the case study approach as perceived by one of the leaders in case study work will also pick up this book. Researchers and policymakers in social service agencies may also be interested because case studies are increasingly part of evaluation strategies."

--Corrine Glesne, University of Vermont

Unique in his approach and style, Robert E. Stake draws from naturalistic, holistic, ethnographic, phenomenological, and biographic methods to present a disciplined, qualitative exploration of case study methods. In his exploration, Stake uses and annotates an actual case, at Harper School, to demonstrate to readers how to resolve some of the major issues of case study research; for example, how to select the case (or cases) that will maximize learning, how to generalize what is learned from one case to another, and how to interpret what is learned from a case. Uniquely, this book legitimizes direct interpretation as a case research method. It covers such topics as the differences between quantitative and qualitative approaches to case study; data gathering, including document review; coding, sorting, and pattern analysis; the roles of the researcher, triangulation; and reporting a case study. Also provided are end-of-chapter "workshops" that help students focus on new concepts.

Written with the inspired and thought-provoking style of a master storyteller, The Art of Case Study Research helps readers chart their way through the labyrinth of case study research.

A Guide to Data Collection: Methods, Process, and Tools

Whether your field is development economics, international development, the nonprofit sector, or myriad other industries, effective data collection is essential. It informs decision-making and increases your organization’s impact. However, the process of data collection can be complex and challenging. If you’re in the beginning stages of creating a data collection process, this guide is for you. It outlines tested methods, efficient procedures, and effective tools to help you improve your data collection activities and outcomes. At SurveyCTO, we’ve used our years of experience and expertise to build a robust, secure, and scalable mobile data collection platform. It’s trusted by respected institutions like The World Bank, J-PAL, Oxfam, and the Gates Foundation, and it’s changed the way many organizations collect and use data. With this guide, we want to share what we know and help you get ready to take the first step in your data collection journey.

Main takeaways from this guide

• Before starting the data collection process, define your goals and identify data sources, which can be primary (first-hand research) or secondary (existing resources).
• Your data collection method should align with your goals, resources, and the nature of the data needed. Surveys, interviews, observations, focus groups, and forms are common data collection methods. 
• Sampling involves selecting a representative group from a larger population. Choosing the right sampling method to gather representative and relevant data is crucial.
• Crafting effective data collection instruments like surveys and questionnaires is key. Instruments should undergo rigorous testing for reliability and accuracy.
• Data collection is an ongoing, iterative process that demands real-time monitoring and adjustments to ensure high-quality, reliable results.

• Common challenges in data collection include data quality and consistency issues, data security concerns, and limitations with offline data collection. Employing robust data validation processes, implementing strong security protocols, and using offline-enabled data collection tools can help overcome these challenges.
• Data collection, entry, and management tools and data analysis, visualization, reporting, and workflow tools can streamline the data collection process, improve data quality, and facilitate data analysis.

What is data collection?

The traditional definition of data collection might lead us to think of gathering information through surveys, observations, or interviews. However, the modern-age definition of data collection extends beyond conducting surveys and observations. It encompasses the systematic gathering and recording of any kind of information through digital or manual methods. Data collection can be as routine as a doctor logging a patient’s information into an electronic medical record system during each clinic visit, or as specific as keeping a record of mosquito nets delivered to a rural household.

Getting started with data collection

Before starting your data collection process, you must clearly understand what you aim to achieve and how you’ll get there. Below are some actionable steps to help you get started.

1. Define your goals

Defining your goals is a crucial first step. Engage relevant stakeholders and team members in an iterative and collaborative process to establish clear goals. It’s important that projects start with the identification of key questions and desired outcomes to ensure you focus your efforts on gathering the right information. 

Start by understanding the purpose of your project– what problem are you trying to solve, or what change do you want to bring about? Think about your project’s potential outcomes and obstacles and try to anticipate what kind of data would be useful in these scenarios. Consider who will be using the data you collect and what data would be the most valuable to them. Think about the long-term effects of your project and how you will measure these over time. Lastly, leverage any historical data from previous projects to help you refine key questions that may have been overlooked previously. 

Once questions and outcomes are established, your data collection goals may still vary based on the context of your work. To demonstrate, let’s use the example of an international organization working on a healthcare project in a remote area.

• If you’re a researcher , your goal will revolve around collecting primary data to answer specific questions. This could involve designing a survey or conducting interviews to collect first-hand data on patient improvement, disease or illness prevalence, and behavior changes (such as an increase in patients seeking healthcare).
• If you’re part of the monitoring and evaluation ( M&E) team , your goal will revolve around measuring the success of your healthcare project. This could involve collecting primary data through surveys or observations and developing a dashboard to display real-time metrics like the number of patients treated, percentage of reduction in incidences of disease,, and average patient wait times. Your focus would be using this data to implement any needed program changes and ensure your project meets its objectives.
• If you’re part of a field team , your goal will center around the efficient and accurate execution of project plans. You might be responsible for using data collection tools to capture pertinent information in different settings, such as in interviews takendirectly from the sample community or over the phone. The data you collect and manage will directly influence the operational efficiency of the project and assist in achieving the project’s overarching objectives.

2. Identify your data sources

The crucial next step in your research process is determining your data source. Essentially, there are two main data types to choose from: primary and secondary.

• Primary data is the information you collect directly from first-hand engagements. It’s gathered specifically for your research and tailored to your research question. Primary data collection methods can range from surveys and interviews to focus groups and observations. Because you design the data collection process, primary data can offer precise, context-specific information directly related to your research objectives. For example, suppose you are investigating the impact of a new education policy. In that case, primary data might be collected through surveys distributed to teachers or interviews with school administrators dealing directly with the policy’s implementation.
• Secondary data, on the other hand, is derived from resources that already exist. This can include information gathered for other research projects, administrative records, historical documents, statistical databases, and more. While not originally collected for your specific study, secondary data can offer valuable insights and background information that complement your primary data. For instance, continuing with the education policy example, secondary data might involve academic articles about similar policies, government reports on education or previous survey data about teachers’ opinions on educational reforms.

While both types of data have their strengths, this guide will predominantly focus on primary data and the methods to collect it. Primary data is often emphasized in research because it provides fresh, first-hand insights that directly address your research questions. Primary data also allows for more control over the data collection process, ensuring data is relevant, accurate, and up-to-date.

However, secondary data can offer critical context, allow for longitudinal analysis, save time and resources, and provide a comparative framework for interpreting your primary data. It can be a crucial backdrop against which your primary data can be understood and analyzed. While we focus on primary data collection methods in this guide, we encourage you not to overlook the value of incorporating secondary data into your research design where appropriate.

3. Choose your data collection method

When choosing your data collection method, there are many options at your disposal. Data collection is not limited to methods like surveys and interviews. In fact, many of the processes in our daily lives serve the goal of collecting data, from intake forms to automated endpoints, such as payment terminals and mass transit card readers. Let us dive into some common types of data collection methods: 

Surveys and Questionnaires

Surveys and questionnaires are tools for gathering information about a group of individuals, typically by asking them predefined questions. They can be used to collect quantitative and qualitative data and be administered in various ways, including online, over the phone, in person (offline), or by mail.

• Advantages : They allow researchers to reach many participants quickly and cost-effectively, making them ideal for large-scale studies. The structured format of questions makes analysis easier.
• Disadvantages : They may not capture complex or nuanced information as participants are limited to predefined response choices. Also, there can be issues with response bias, where participants might provide socially desirable answers rather than honest ones.

Interviews involve a one-on-one conversation between the researcher and the participant. The interviewer asks open-ended questions to gain detailed information about the participant’s thoughts, feelings, experiences, and behaviors.

• Advantages : They allow for an in-depth understanding of the topic at hand. The researcher can adapt the questioning in real time based on the participant’s responses, allowing for more flexibility.
• Disadvantages : They can be time-consuming and resource-intensive, as they require trained interviewers and a significant amount of time for both conducting and analyzing responses. They may also introduce interviewer bias if not conducted carefully, due to how an interviewer presents questions and perceives the respondent, and how the respondent perceives the interviewer. 

Observations

Observations involve directly observing and recording behavior or other phenomena as they occur in their natural settings.

• Advantages : Observations can provide valuable contextual information, as researchers can study behavior in the environment where it naturally occurs, reducing the risk of artificiality associated with laboratory settings or self-reported measures.
• Disadvantages : Observational studies may suffer from observer bias, where the observer’s expectations or biases could influence their interpretation of the data. Also, some behaviors might be altered if subjects are aware they are being observed.

Focus Groups

Focus groups are guided discussions among selected individuals to gain information about their views and experiences.

• Advantages : Focus groups allow for interaction among participants, which can generate a diverse range of opinions and ideas. They are good for exploring new topics where there is little pre-existing knowledge.
• Disadvantages : Dominant voices in the group can sway the discussion, potentially silencing less assertive participants. They also require skilled facilitators to moderate the discussion effectively.

Forms are standardized documents with blank fields for collecting data in a systematic manner. They are often used in fields like Customer Relationship Management (CRM) or Electronic Medical Records (EMR) data entry. Surveys may also be referred to as forms.

• Advantages : Forms are versatile, easy to use, and efficient for data collection. They can streamline workflows by standardizing the data entry process.
• Disadvantages : They may not provide in-depth insights as the responses are typically structured and limited. There is also potential for errors in data entry, especially when done manually.

Selecting the right data collection method should be an intentional process, taking into consideration the unique requirements of your project. The method selected should align with your goals, available resources, and the nature of the data you need to collect.

If you aim to collect quantitative data, surveys, questionnaires, and forms can be excellent tools, particularly for large-scale studies. These methods are suited to providing structured responses that can be analyzed statistically, delivering solid numerical data.

However, if you’re looking to uncover a deeper understanding of a subject, qualitative data might be more suitable. In such cases, interviews, observations, and focus groups can provide richer, more nuanced insights. These methods allow you to explore experiences, opinions, and behaviors deeply. Some surveys can also include open-ended questions that provide qualitative data.

The cost of data collection is also an important consideration. If you have budget constraints, in-depth, in-person conversations with every member of your target population may not be practical. In such cases, distributing questionnaires or forms can be a cost-saving approach.

Additional considerations include language barriers and connectivity issues. If your respondents speak different languages, consider translation services or multilingual data collection tools . If your target population resides in areas with limited connectivity and your method will be to collect data using mobile devices, ensure your tool provides offline data collection , which will allow you to carry out your data collection plan without internet connectivity.

4. Determine your sampling method

Now that you’ve established your data collection goals and how you’ll collect your data, the next step is deciding whom to collect your data from. Sampling involves carefully selecting a representative group from a larger population. Choosing the right sampling method is crucial for gathering representative and relevant data that aligns with your data collection goal.

Consider the following guidelines to choose the appropriate sampling method for your research goal and data collection method:

• Understand Your Target Population: Start by conducting thorough research of your target population. Understand who they are, their characteristics, and subgroups within the population.
• Anticipate and Minimize Biases: Anticipate and address potential biases within the target population to help minimize their impact on the data. For example, will your sampling method accurately reflect all ages, gender, cultures, etc., of your target population? Are there barriers to participation for any subgroups? Your sampling method should allow you to capture the most accurate representation of your target population.
• Maintain Cost-Effective Practices: Consider the cost implications of your chosen sampling methods. Some sampling methods will require more resources, time, and effort. Your chosen sampling method should balance the cost factors with the ability to collect your data effectively and accurately. 
• Consider Your Project’s Objectives: Tailor the sampling method to meet your specific objectives and constraints, such as M&E teams requiring real-time impact data and researchers needing representative samples for statistical analysis.

By adhering to these guidelines, you can make informed choices when selecting a sampling method, maximizing the quality and relevance of your data collection efforts.

5. Identify and train collectors

Not every data collection use case requires data collectors, but training individuals responsible for data collection becomes crucial in scenarios involving field presence.

The SurveyCTO platform supports both self-response survey modes and surveys that require a human field worker to do in-person interviews. Whether you’re hiring and training data collectors, utilizing an existing team, or training existing field staff, we offer comprehensive guidance and the right tools to ensure effective data collection practices.  

Here are some common training approaches for data collectors:

• In-Class Training: Comprehensive sessions covering protocols, survey instruments, and best practices empower data collectors with skills and knowledge.
• Tests and Assessments: Assessments evaluate collectors’ understanding and competence, highlighting areas where additional support is needed.
• Mock Interviews: Simulated interviews refine collectors’ techniques and communication skills.
• Pre-Recorded Training Sessions: Accessible reinforcement and self-paced learning to refresh and stay updated.

Training data collectors is vital for successful data collection techniques. Your training should focus on proper instrument usage and effective interaction with respondents, including communication skills, cultural literacy, and ethical considerations.

Remember, training is an ongoing process. Knowledge gaps and issues may arise in the field, necessitating further training.

Moving Ahead: Iterative Steps in Data Collection

Once you’ve established the preliminary elements of your data collection process, you’re ready to start your data collection journey. In this section, we’ll delve into the specifics of designing and testing your instruments, collecting data, and organizing data while embracing the iterative nature of the data collection process, which requires diligent monitoring and making adjustments when needed.

6. Design and test your instruments

Designing effective data collection instruments like surveys and questionnaires is key. It’s crucial to prioritize respondent consent and privacy to ensure the integrity of your research. Thoughtful design and careful testing of survey questions are essential for optimizing research insights. Other critical considerations are: 

• Clear and Unbiased Question Wording: Craft unambiguous, neutral questions free from bias to gather accurate and meaningful data. For example, instead of asking, “Shouldn’t we invest more into renewable energy that will combat the effects of climate change?” ask your question in a neutral way that allows the respondent to voice their thoughts. For example: “What are your thoughts on investing more in renewable energy?”
• Logical Ordering and Appropriate Response Format: Arrange questions logically and choose response formats (such as multiple-choice, Likert scale, or open-ended) that suit the nature of the data you aim to collect.
• Coverage of Relevant Topics: Ensure that your instrument covers all topics pertinent to your data collection goals while respecting cultural and social sensitivities. Make sure your instrument avoids assumptions, stereotypes, and languages or topics that could be considered offensive or taboo in certain contexts. The goal is to avoid marginalizing or offending respondents based on their social or cultural background.
• Collect Only Necessary Data: Design survey instruments that focus solely on gathering the data required for your research objectives, avoiding unnecessary information.
• Language(s) of the Respondent Population: Tailor your instruments to accommodate the languages your target respondents speak, offering translated versions if needed. Similarly, take into account accessibility for respondents who can’t read by offering alternative formats like images in place of text.
• Desired Length of Time for Completion: Respect respondents’ time by designing instruments that can be completed within a reasonable timeframe, balancing thoroughness with engagement. Having a general timeframe for the amount of time needed to complete a response will also help you weed out bad responses. For example, a response that was rushed and completed outside of your response timeframe could indicate a response that needs to be excluded.
• Collecting and Documenting Respondents’ Consent and Privacy: Ensure a robust consent process, transparent data usage communication, and privacy protection throughout data collection.

Perform Cognitive Interviewing

Cognitive interviewing is a method used to refine survey instruments and improve the accuracy of survey responses by evaluating how respondents understand, process, and respond to the instrument’s questions. In practice, cognitive interviewing involves an interview with the respondent, asking them to verbalize their thoughts as they interact with the instrument. By actively probing and observing their responses, you can identify and address ambiguities, ensuring accurate data collection.  

Thoughtful question wording, well-organized response options, and logical sequencing enhance comprehension, minimize biases, and ensure accurate data collection. Iterative testing and refinement based on respondent feedback improve the validity, reliability, and actionability of insights obtained.

Put Your Instrument to the Test

Through rigorous testing, you can uncover flaws, ensure reliability, maximize accuracy, and validate your instrument’s performance. This can be achieved by:

• Conducting pilot testing to enhance the reliability and effectiveness of data collection. Administer the instrument, identify difficulties, gather feedback, and assess performance in real-world conditions.
• Making revisions based on pilot testing to enhance clarity, accuracy, usability, and participant satisfaction. Refine questions, instructions, and format for effective data collection.
• Continuously iterating and refining your instrument based on feedback and real-world testing. This ensures reliable, accurate, and audience-aligned methods of data collection. Additionally, this ensures your instrument adapts to changes, incorporates insights, and maintains ongoing effectiveness.

7. Collect your data

Now that you have your well-designed survey, interview questions, observation plan, or form, it’s time to implement it and gather the needed data. Data collection is not a one-and-done deal; it’s an ongoing process that demands attention to detail. Imagine spending weeks collecting data, only to discover later that a significant portion is unusable due to incomplete responses, improper collection methods, or falsified responses. To avoid such setbacks, adopt an iterative approach.

Leverage data collection tools with real-time monitoring to proactively identify outliers and issues. Take immediate action by fine-tuning your instruments, optimizing the data collection process, addressing concerns like additional training, or reevaluating personnel responsible for inaccurate data (for example, a field worker who sits in a coffee shop entering fake responses rather than doing the work of knocking on doors).

SurveyCTO’s Data Explorer was specifically designed to fulfill this requirement, empowering you to monitor incoming data, gain valuable insights, and know where changes may be needed. Embracing this iterative approach ensures ongoing improvement in data collection, resulting in more reliable and precise results.

8. Clean and organize your data

After data collection, the next step is to clean and organize the data to ensure its integrity and usability.

• Data Cleaning: This stage involves sifting through your data to identify and rectify any errors, inconsistencies, or missing values. It’s essential to maintain the accuracy of your data and ensure that it’s reliable for further analysis. Data cleaning can uncover duplicates, outliers, and gaps that could skew your results if left unchecked. With real-time data monitoring , this continuous cleaning process keeps your data precise and current throughout the data collection period. Similarly, review and corrections workflows allow you to monitor the quality of your incoming data.
• Organizing Your Data: Post-cleaning, it’s time to organize your data for efficient analysis and interpretation. Labeling your data using appropriate codes or categorizations can simplify navigation and streamline the extraction of insights. When you use a survey or form, labeling your data is often not necessary because you can design the instrument to collect in the right categories or return the right codes. An organized dataset is easier to manage, analyze, and interpret, ensuring that your collection efforts are not wasted but lead to valuable, actionable insights.

Remember, each stage of the data collection process, from design to cleaning, is iterative and interconnected. By diligently cleaning and organizing your data, you are setting the stage for robust, meaningful analysis that can inform your data-driven decisions and actions.

What happens after data collection?

The data collection journey takes us next into data analysis, where you’ll uncover patterns, empowering informed decision-making for researchers, evaluation teams, and field personnel.

Process and Analyze Your Data

Explore data through statistical and qualitative techniques to discover patterns, correlations, and insights during this pivotal stage. It’s about extracting the essence of your data and translating numbers into knowledge. Whether applying descriptive statistics, conducting regression analysis, or using thematic coding for qualitative data, this process drives decision-making and charts the path toward actionable outcomes.

Interpret and Report Your Results

Interpreting and reporting your data brings meaning and context to the numbers. Translating raw data into digestible insights for informed decision-making and effective stakeholder communication is critical.

The approach to interpretation and reporting varies depending on the perspective and role:

• Researchers often lean heavily on statistical methods to identify trends, extract meaningful conclusions, and share their findings in academic circles, contributing to their knowledge pool.
• M&E teams typically produce comprehensive reports, shedding light on the effectiveness and impact of programs. These reports guide internal and sometimes external stakeholders, supporting informed decisions and driving program improvements.

Field teams provide a first-hand perspective. Since they are often the first to see the results of the practical implementation of data, field teams are instrumental in providing immediate feedback loops on project initiatives. Field teams do the work that provides context to help research and M&E teams understand external factors like the local environment, cultural nuances, and logistical challenges that impact data results.

Safely store and handle data

Throughout the data collection process, and after it has been collected, it is vital to follow best practices for storing and handling data to ensure the integrity of your research. While the specifics of how to best store and handle data will depend on your project, here are some important guidelines to keep in mind:

• Use cloud storage to hold your data if possible, since this is safer than storing data on hard drives and keeps it more accessible,
• Periodically back up and purge old data from your system, since it’s safer to not retain data longer than necessary,
• If you use mobile devices to collect and store data, use options for private, internal apps-specific storage if and when possible,
• Restrict access to stored data to only those who need to work with that data.

Further considerations for data safety are discussed below in the section on data security .

Remember to uphold ethical standards in interpreting and reporting your data, regardless of your role. Clear communication, respectful handling of sensitive information, and adhering to confidentiality and privacy rights are all essential to fostering trust, promoting transparency, and bolstering your work’s credibility.

Common Data Collection Challenges

Data collection is vital to data-driven initiatives, but it comes with challenges. Addressing common challenges such as poor data quality, privacy concerns, inadequate sample sizes, and bias is essential to ensure the collected data is reliable, trustworthy, and secure. 

In this section, we’ll explore three major challenges: data quality and consistency issues, data security concerns, and limitations with offline data collection , along with strategies to overcome them.

Data Quality and Consistency

Data quality and consistency refer to data accuracy and reliability throughout the collection and analysis process. 

Challenges such as incomplete or missing data, data entry errors, measurement errors, and data coding/categorization errors can impact the integrity and usefulness of the data. 

To navigate these complexities and maintain high standards, consistency, and integrity in the dataset:

• Implement robust data validation processes, 
• Ensure proper training for data entry personnel, 
• Employ automated data validation techniques, and 
• Conduct regular data quality audits.

Data security

Data security encompasses safeguarding data through ensuring data privacy and confidentiality, securing storage and backup, and controlling data sharing and access.

Challenges include the risk of potential breaches, unauthorized access, and the need to comply with data protection regulations.

To address these setbacks and maintain privacy, trust, and confidence during the data collection process: 

• Use encryption and authentication methods, 
• Implement robust security protocols,

Data Collection Methods | Step-by-Step Guide & Examples

Published on 4 May 2022 by Pritha Bhandari .

Data collection is a systematic process of gathering observations or measurements. Whether you are performing research for business, governmental, or academic purposes, data collection allows you to gain first-hand knowledge and original insights into your research problem .

While methods and aims may differ between fields, the overall process of data collection remains largely the same. Before you begin collecting data, you need to consider:

• The  aim of the research
• The type of data that you will collect
• The methods and procedures you will use to collect, store, and process the data

To collect high-quality data that is relevant to your purposes, follow these four steps.

Table of contents

Step 1: define the aim of your research, step 2: choose your data collection method, step 3: plan your data collection procedures, step 4: collect the data, frequently asked questions about data collection.

Before you start the process of data collection, you need to identify exactly what you want to achieve. You can start by writing a problem statement : what is the practical or scientific issue that you want to address, and why does it matter?

Next, formulate one or more research questions that precisely define what you want to find out. Depending on your research questions, you might need to collect quantitative or qualitative data :

• Quantitative data is expressed in numbers and graphs and is analysed through statistical methods .
• Qualitative data is expressed in words and analysed through interpretations and categorisations.

If your aim is to test a hypothesis , measure something precisely, or gain large-scale statistical insights, collect quantitative data. If your aim is to explore ideas, understand experiences, or gain detailed insights into a specific context, collect qualitative data.

If you have several aims, you can use a mixed methods approach that collects both types of data.

• Your first aim is to assess whether there are significant differences in perceptions of managers across different departments and office locations.
• Your second aim is to gather meaningful feedback from employees to explore new ideas for how managers can improve.

Prevent plagiarism, run a free check.

Based on the data you want to collect, decide which method is best suited for your research.

• Experimental research is primarily a quantitative method.
• Interviews , focus groups , and ethnographies are qualitative methods.
• Surveys , observations, archival research, and secondary data collection can be quantitative or qualitative methods.

Carefully consider what method you will use to gather data that helps you directly answer your research questions.

When you know which method(s) you are using, you need to plan exactly how you will implement them. What procedures will you follow to make accurate observations or measurements of the variables you are interested in?

For instance, if you’re conducting surveys or interviews, decide what form the questions will take; if you’re conducting an experiment, make decisions about your experimental design .

Sometimes your variables can be measured directly: for example, you can collect data on the average age of employees simply by asking for dates of birth. However, often you’ll be interested in collecting data on more abstract concepts or variables that can’t be directly observed.

Operationalisation means turning abstract conceptual ideas into measurable observations. When planning how you will collect data, you need to translate the conceptual definition of what you want to study into the operational definition of what you will actually measure.

• You ask managers to rate their own leadership skills on 5-point scales assessing the ability to delegate, decisiveness, and dependability.
• You ask their direct employees to provide anonymous feedback on the managers regarding the same topics.

You may need to develop a sampling plan to obtain data systematically. This involves defining a population , the group you want to draw conclusions about, and a sample, the group you will actually collect data from.

Your sampling method will determine how you recruit participants or obtain measurements for your study. To decide on a sampling method you will need to consider factors like the required sample size, accessibility of the sample, and time frame of the data collection.

Standardising procedures

If multiple researchers are involved, write a detailed manual to standardise data collection procedures in your study.

This means laying out specific step-by-step instructions so that everyone in your research team collects data in a consistent way – for example, by conducting experiments under the same conditions and using objective criteria to record and categorise observations.

This helps ensure the reliability of your data, and you can also use it to replicate the study in the future.

Creating a data management plan

Before beginning data collection, you should also decide how you will organise and store your data.

• If you are collecting data from people, you will likely need to anonymise and safeguard the data to prevent leaks of sensitive information (e.g. names or identity numbers).
• If you are collecting data via interviews or pencil-and-paper formats, you will need to perform transcriptions or data entry in systematic ways to minimise distortion.
• You can prevent loss of data by having an organisation system that is routinely backed up.

Finally, you can implement your chosen methods to measure or observe the variables you are interested in.

The closed-ended questions ask participants to rate their manager’s leadership skills on scales from 1 to 5. The data produced is numerical and can be statistically analysed for averages and patterns.

To ensure that high-quality data is recorded in a systematic way, here are some best practices:

• Record all relevant information as and when you obtain data. For example, note down whether or how lab equipment is recalibrated during an experimental study.
• Double-check manual data entry for errors.
• If you collect quantitative data, you can assess the reliability and validity to get an indication of your data quality.

Data collection is the systematic process by which observations or measurements are gathered in research. It is used in many different contexts by academics, governments, businesses, and other organisations.

When conducting research, collecting original data has significant advantages:

• You can tailor data collection to your specific research aims (e.g., understanding the needs of your consumers or user testing your website).
• You can control and standardise the process for high reliability and validity (e.g., choosing appropriate measurements and sampling methods ).

However, there are also some drawbacks: data collection can be time-consuming, labour-intensive, and expensive. In some cases, it’s more efficient to use secondary data that has already been collected by someone else, but the data might be less reliable.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.

Reliability and validity are both about how well a method measures something:

• Reliability refers to the  consistency of a measure (whether the results can be reproduced under the same conditions).
• Validity   refers to the  accuracy of a measure (whether the results really do represent what they are supposed to measure).

If you are doing experimental research , you also have to consider the internal and external validity of your experiment.

In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .

Operationalisation means turning abstract conceptual ideas into measurable observations.

For example, the concept of social anxiety isn’t directly observable, but it can be operationally defined in terms of self-rating scores, behavioural avoidance of crowded places, or physical anxiety symptoms in social situations.

Before collecting data , it’s important to consider how you will operationalise the variables that you want to measure.

Designing and Conducting Case Studies

This guide examines case studies, a form of qualitative descriptive research that is used to look at individuals, a small group of participants, or a group as a whole. Researchers collect data about participants using participant and direct observations, interviews, protocols, tests, examinations of records, and collections of writing samples. Starting with a definition of the case study, the guide moves to a brief history of this research method. Using several well documented case studies, the guide then looks at applications and methods including data collection and analysis. A discussion of ways to handle validity, reliability, and generalizability follows, with special attention to case studies as they are applied to composition studies. Finally, this guide examines the strengths and weaknesses of case studies.

Definition and Overview

Case study refers to the collection and presentation of detailed information about a particular participant or small group, frequently including the accounts of subjects themselves. A form of qualitative descriptive research, the case study looks intensely at an individual or small participant pool, drawing conclusions only about that participant or group and only in that specific context. Researchers do not focus on the discovery of a universal, generalizable truth, nor do they typically look for cause-effect relationships; instead, emphasis is placed on exploration and description.

Case studies typically examine the interplay of all variables in order to provide as complete an understanding of an event or situation as possible. This type of comprehensive understanding is arrived at through a process known as thick description, which involves an in-depth description of the entity being evaluated, the circumstances under which it is used, the characteristics of the people involved in it, and the nature of the community in which it is located. Thick description also involves interpreting the meaning of demographic and descriptive data such as cultural norms and mores, community values, ingrained attitudes, and motives.

Unlike quantitative methods of research, like the survey, which focus on the questions of who, what, where, how much, and how many, and archival analysis, which often situates the participant in some form of historical context, case studies are the preferred strategy when how or why questions are asked. Likewise, they are the preferred method when the researcher has little control over the events, and when there is a contemporary focus within a real life context. In addition, unlike more specifically directed experiments, case studies require a problem that seeks a holistic understanding of the event or situation in question using inductive logic--reasoning from specific to more general terms.

In scholarly circles, case studies are frequently discussed within the context of qualitative research and naturalistic inquiry. Case studies are often referred to interchangeably with ethnography, field study, and participant observation. The underlying philosophical assumptions in the case are similar to these types of qualitative research because each takes place in a natural setting (such as a classroom, neighborhood, or private home), and strives for a more holistic interpretation of the event or situation under study.

Unlike more statistically-based studies which search for quantifiable data, the goal of a case study is to offer new variables and questions for further research. F.H. Giddings, a sociologist in the early part of the century, compares statistical methods to the case study on the basis that the former are concerned with the distribution of a particular trait, or a small number of traits, in a population, whereas the case study is concerned with the whole variety of traits to be found in a particular instance" (Hammersley 95).

Case studies are not a new form of research; naturalistic inquiry was the primary research tool until the development of the scientific method. The fields of sociology and anthropology are credited with the primary shaping of the concept as we know it today. However, case study research has drawn from a number of other areas as well: the clinical methods of doctors; the casework technique being developed by social workers; the methods of historians and anthropologists, plus the qualitative descriptions provided by quantitative researchers like LePlay; and, in the case of Robert Park, the techniques of newspaper reporters and novelists.

Park was an ex-newspaper reporter and editor who became very influential in developing sociological case studies at the University of Chicago in the 1920s. As a newspaper professional he coined the term "scientific" or "depth" reporting: the description of local events in a way that pointed to major social trends. Park viewed the sociologist as "merely a more accurate, responsible, and scientific reporter." Park stressed the variety and value of human experience. He believed that sociology sought to arrive at natural, but fluid, laws and generalizations in regard to human nature and society. These laws weren't static laws of the kind sought by many positivists and natural law theorists, but rather, they were laws of becoming--with a constant possibility of change. Park encouraged students to get out of the library, to quit looking at papers and books, and to view the constant experiment of human experience. He writes, "Go and sit in the lounges of the luxury hotels and on the doorsteps of the flophouses; sit on the Gold Coast settees and on the slum shakedowns; sit in the Orchestra Hall and in the Star and Garter Burlesque. In short, gentlemen [sic], go get the seats of your pants dirty in real research."

But over the years, case studies have drawn their share of criticism. In fact, the method had its detractors from the start. In the 1920s, the debate between pro-qualitative and pro-quantitative became quite heated. Case studies, when compared to statistics, were considered by many to be unscientific. From the 1930's on, the rise of positivism had a growing influence on quantitative methods in sociology. People wanted static, generalizable laws in science. The sociological positivists were looking for stable laws of social phenomena. They criticized case study research because it failed to provide evidence of inter subjective agreement. Also, they condemned it because of the few number of cases studied and that the under-standardized character of their descriptions made generalization impossible. By the 1950s, quantitative methods, in the form of survey research, had become the dominant sociological approach and case study had become a minority practice.

Educational Applications

The 1950's marked the dawning of a new era in case study research, namely that of the utilization of the case study as a teaching method. "Instituted at Harvard Business School in the 1950s as a primary method of teaching, cases have since been used in classrooms and lecture halls alike, either as part of a course of study or as the main focus of the course to which other teaching material is added" (Armisted 1984). The basic purpose of instituting the case method as a teaching strategy was "to transfer much of the responsibility for learning from the teacher on to the student, whose role, as a result, shifts away from passive absorption toward active construction" (Boehrer 1990). Through careful examination and discussion of various cases, "students learn to identify actual problems, to recognize key players and their agendas, and to become aware of those aspects of the situation that contribute to the problem" (Merseth 1991). In addition, students are encouraged to "generate their own analysis of the problems under consideration, to develop their own solutions, and to practically apply their own knowledge of theory to these problems" (Boyce 1993). Along the way, students also develop "the power to analyze and to master a tangled circumstance by identifying and delineating important factors; the ability to utilize ideas, to test them against facts, and to throw them into fresh combinations" (Merseth 1991).

In addition to the practical application and testing of scholarly knowledge, case discussions can also help students prepare for real-world problems, situations and crises by providing an approximation of various professional environments (i.e. classroom, board room, courtroom, or hospital). Thus, through the examination of specific cases, students are given the opportunity to work out their own professional issues through the trials, tribulations, experiences, and research findings of others. An obvious advantage to this mode of instruction is that it allows students the exposure to settings and contexts that they might not otherwise experience. For example, a student interested in studying the effects of poverty on minority secondary student's grade point averages and S.A.T. scores could access and analyze information from schools as geographically diverse as Los Angeles, New York City, Miami, and New Mexico without ever having to leave the classroom.

The case study method also incorporates the idea that students can learn from one another "by engaging with each other and with each other's ideas, by asserting something and then having it questioned, challenged and thrown back at them so that they can reflect on what they hear, and then refine what they say" (Boehrer 1990). In summary, students can direct their own learning by formulating questions and taking responsibility for the study.

Types and Design Concerns

Researchers use multiple methods and approaches to conduct case studies.

Types of Case Studies

Under the more generalized category of case study exist several subdivisions, each of which is custom selected for use depending upon the goals and/or objectives of the investigator. These types of case study include the following:

Illustrative Case Studies These are primarily descriptive studies. They typically utilize one or two instances of an event to show what a situation is like. Illustrative case studies serve primarily to make the unfamiliar familiar and to give readers a common language about the topic in question.

Exploratory (or pilot) Case Studies These are condensed case studies performed before implementing a large scale investigation. Their basic function is to help identify questions and select types of measurement prior to the main investigation. The primary pitfall of this type of study is that initial findings may seem convincing enough to be released prematurely as conclusions.

Cumulative Case Studies These serve to aggregate information from several sites collected at different times. The idea behind these studies is the collection of past studies will allow for greater generalization without additional cost or time being expended on new, possibly repetitive studies.

Critical Instance Case Studies These examine one or more sites for either the purpose of examining a situation of unique interest with little to no interest in generalizability, or to call into question or challenge a highly generalized or universal assertion. This method is useful for answering cause and effect questions.

Identifying a Theoretical Perspective

Much of the case study's design is inherently determined for researchers, depending on the field from which they are working. In composition studies, researchers are typically working from a qualitative, descriptive standpoint. In contrast, physicists will approach their research from a more quantitative perspective. Still, in designing the study, researchers need to make explicit the questions to be explored and the theoretical perspective from which they will approach the case. The three most commonly adopted theories are listed below:

Individual Theories These focus primarily on the individual development, cognitive behavior, personality, learning and disability, and interpersonal interactions of a particular subject.

Organizational Theories These focus on bureaucracies, institutions, organizational structure and functions, or excellence in organizational performance.

Social Theories These focus on urban development, group behavior, cultural institutions, or marketplace functions.

Two examples of case studies are used consistently throughout this chapter. The first, a study produced by Berkenkotter, Huckin, and Ackerman (1988), looks at a first year graduate student's initiation into an academic writing program. The study uses participant-observer and linguistic data collecting techniques to assess the student's knowledge of appropriate discourse conventions. Using the pseudonym Nate to refer to the subject, the study sought to illuminate the particular experience rather than to generalize about the experience of fledgling academic writers collectively.

For example, in Berkenkotter, Huckin, and Ackerman's (1988) study we are told that the researchers are interested in disciplinary communities. In the first paragraph, they ask what constitutes membership in a disciplinary community and how achieving membership might affect a writer's understanding and production of texts. In the third paragraph they state that researchers must negotiate their claims "within the context of his sub specialty's accepted knowledge and methodology." In the next paragraph they ask, "How is literacy acquired? What is the process through which novices gain community membership? And what factors either aid or hinder students learning the requisite linguistic behaviors?" This introductory section ends with a paragraph in which the study's authors claim that during the course of the study, the subject, Nate, successfully makes the transition from "skilled novice" to become an initiated member of the academic discourse community and that his texts exhibit linguistic changes which indicate this transition. In the next section the authors make explicit the sociolinguistic theoretical and methodological assumptions on which the study is based (1988). Thus the reader has a good understanding of the authors' theoretical background and purpose in conducting the study even before it is explicitly stated on the fourth page of the study. "Our purpose was to examine the effects of the educational context on one graduate student's production of texts as he wrote in different courses and for different faculty members over the academic year 1984-85." The goal of the study then, was to explore the idea that writers must be initiated into a writing community, and that this initiation will change the way one writes.

The second example is Janet Emig's (1971) study of the composing process of a group of twelfth graders. In this study, Emig seeks to answer the question of what happens to the self as a result educational stimuli in terms of academic writing. The case study used methods such as protocol analysis, tape-recorded interviews, and discourse analysis.

In the case of Janet Emig's (1971) study of the composing process of eight twelfth graders, four specific hypotheses were made:

• Twelfth grade writers engage in two modes of composing: reflexive and extensive.
• These differences can be ascertained and characterized through having the writers compose aloud their composition process.
• A set of implied stylistic principles governs the writing process.
• For twelfth grade writers, extensive writing occurs chiefly as a school-sponsored activity, or reflexive, as a self-sponsored activity.

In this study, the chief distinction is between the two dominant modes of composing among older, secondary school students. The distinctions are:

• The reflexive mode, which focuses on the writer's thoughts and feelings.
• The extensive mode, which focuses on conveying a message.

Emig also outlines the specific questions which guided the research in the opening pages of her Review of Literature , preceding the report.

Designing a Case Study

After considering the different sub categories of case study and identifying a theoretical perspective, researchers can begin to design their study. Research design is the string of logic that ultimately links the data to be collected and the conclusions to be drawn to the initial questions of the study. Typically, research designs deal with at least four problems:

• What questions to study
• What data are relevant
• What data to collect
• How to analyze that data

In other words, a research design is basically a blueprint for getting from the beginning to the end of a study. The beginning is an initial set of questions to be answered, and the end is some set of conclusions about those questions.

Because case studies are conducted on topics as diverse as Anglo-Saxon Literature (Thrane 1986) and AIDS prevention (Van Vugt 1994), it is virtually impossible to outline any strict or universal method or design for conducting the case study. However, Robert K. Yin (1993) does offer five basic components of a research design:

• A study's questions.
• A study's propositions (if any).
• A study's units of analysis.
• The logic that links the data to the propositions.
• The criteria for interpreting the findings.

In addition to these five basic components, Yin also stresses the importance of clearly articulating one's theoretical perspective, determining the goals of the study, selecting one's subject(s), selecting the appropriate method(s) of collecting data, and providing some considerations to the composition of the final report.

Conducting Case Studies

To obtain as complete a picture of the participant as possible, case study researchers can employ a variety of approaches and methods. These approaches, methods, and related issues are discussed in depth in this section.

Method: Single or Multi-modal?

To obtain as complete a picture of the participant as possible, case study researchers can employ a variety of methods. Some common methods include interviews , protocol analyses, field studies, and participant-observations. Emig (1971) chose to use several methods of data collection. Her sources included conversations with the students, protocol analysis, discrete observations of actual composition, writing samples from each student, and school records (Lauer and Asher 1988).

Berkenkotter, Huckin, and Ackerman (1988) collected data by observing classrooms, conducting faculty and student interviews, collecting self reports from the subject, and by looking at the subject's written work.

A study that was criticized for using a single method model was done by Flower and Hayes (1984). In this study that explores the ways in which writers use different forms of knowing to create space, the authors used only protocol analysis to gather data. The study came under heavy fire because of their decision to use only one method.

Participant Selection

Case studies can use one participant, or a small group of participants. However, it is important that the participant pool remain relatively small. The participants can represent a diverse cross section of society, but this isn't necessary.

For example, the Berkenkotter, Huckin, and Ackerman (1988) study looked at just one participant, Nate. By contrast, in Janet Emig's (1971) study of the composition process of twelfth graders, eight participants were selected representing a diverse cross section of the community, with volunteers from an all-white upper-middle-class suburban school, an all-black inner-city school, a racially mixed lower-middle-class school, an economically and racially mixed school, and a university school.

Often, a brief "case history" is done on the participants of the study in order to provide researchers with a clearer understanding of their participants, as well as some insight as to how their own personal histories might affect the outcome of the study. For instance, in Emig's study, the investigator had access to the school records of five of the participants, and to standardized test scores for the remaining three. Also made available to the researcher was the information that three of the eight students were selected as NCTE Achievement Award winners. These personal histories can be useful in later stages of the study when data are being analyzed and conclusions drawn.

Data Collection

There are six types of data collected in case studies:

• Archival records.
• Interviews.
• Direct observation.
• Participant observation.

In the field of composition research, these six sources might be:

• A writer's drafts.
• School records of student writers.
• Transcripts of interviews with a writer.
• Transcripts of conversations between writers (and protocols).
• Videotapes and notes from direct field observations.
• Hard copies of a writer's work on computer.

Depending on whether researchers have chosen to use a single or multi-modal approach for the case study, they may choose to collect data from one or any combination of these sources.

Protocols, that is, transcriptions of participants talking aloud about what they are doing as they do it, have been particularly common in composition case studies. For example, in Emig's (1971) study, the students were asked, in four different sessions, to give oral autobiographies of their writing experiences and to compose aloud three themes in the presence of a tape recorder and the investigator.

In some studies, only one method of data collection is conducted. For example, the Flower and Hayes (1981) report on the cognitive process theory of writing depends on protocol analysis alone. However, using multiple sources of evidence to increase the reliability and validity of the data can be advantageous.

Case studies are likely to be much more convincing and accurate if they are based on several different sources of information, following a corroborating mode. This conclusion is echoed among many composition researchers. For example, in her study of predrafting processes of high and low-apprehensive writers, Cynthia Selfe (1985) argues that because "methods of indirect observation provide only an incomplete reflection of the complex set of processes involved in composing, a combination of several such methods should be used to gather data in any one study." Thus, in this study, Selfe collected her data from protocols, observations of students role playing their writing processes, audio taped interviews with the students, and videotaped observations of the students in the process of composing.

It can be said then, that cross checking data from multiple sources can help provide a multidimensional profile of composing activities in a particular setting. Sharan Merriam (1985) suggests "checking, verifying, testing, probing, and confirming collected data as you go, arguing that this process will follow in a funnel-like design resulting in less data gathering in later phases of the study along with a congruent increase in analysis checking, verifying, and confirming."

It is important to note that in case studies, as in any qualitative descriptive research, while researchers begin their studies with one or several questions driving the inquiry (which influence the key factors the researcher will be looking for during data collection), a researcher may find new key factors emerging during data collection. These might be unexpected patterns or linguistic features which become evident only during the course of the research. While not bearing directly on the researcher's guiding questions, these variables may become the basis for new questions asked at the end of the report, thus linking to the possibility of further research.

Data Analysis

As the information is collected, researchers strive to make sense of their data. Generally, researchers interpret their data in one of two ways: holistically or through coding. Holistic analysis does not attempt to break the evidence into parts, but rather to draw conclusions based on the text as a whole. Flower and Hayes (1981), for example, make inferences from entire sections of their students' protocols, rather than searching through the transcripts to look for isolatable characteristics.

However, composition researchers commonly interpret their data by coding, that is by systematically searching data to identify and/or categorize specific observable actions or characteristics. These observable actions then become the key variables in the study. Sharan Merriam (1988) suggests seven analytic frameworks for the organization and presentation of data:

• The role of participants.
• The network analysis of formal and informal exchanges among groups.
• Historical.
• Thematical.
• Ritual and symbolism.
• Critical incidents that challenge or reinforce fundamental beliefs, practices, and values.

There are two purposes of these frameworks: to look for patterns among the data and to look for patterns that give meaning to the case study.

As stated above, while most researchers begin their case studies expecting to look for particular observable characteristics, it is not unusual for key variables to emerge during data collection. Typical variables coded in case studies of writers include pauses writers make in the production of a text, the use of specific linguistic units (such as nouns or verbs), and writing processes (planning, drafting, revising, and editing). In the Berkenkotter, Huckin, and Ackerman (1988) study, for example, researchers coded the participant's texts for use of connectives, discourse demonstratives, average sentence length, off-register words, use of the first person pronoun, and the ratio of definite articles to indefinite articles.

Since coding is inherently subjective, more than one coder is usually employed. In the Berkenkotter, Huckin, and Ackerman (1988) study, for example, three rhetoricians were employed to code the participant's texts for off-register phrases. The researchers established the agreement among the coders before concluding that the participant used fewer off-register words as the graduate program progressed.

Composing the Case Study Report

In the many forms it can take, "a case study is generically a story; it presents the concrete narrative detail of actual, or at least realistic events, it has a plot, exposition, characters, and sometimes even dialogue" (Boehrer 1990). Generally, case study reports are extensively descriptive, with "the most problematic issue often referred to as being the determination of the right combination of description and analysis" (1990). Typically, authors address each step of the research process, and attempt to give the reader as much context as possible for the decisions made in the research design and for the conclusions drawn.

This contextualization usually includes a detailed explanation of the researchers' theoretical positions, of how those theories drove the inquiry or led to the guiding research questions, of the participants' backgrounds, of the processes of data collection, of the training and limitations of the coders, along with a strong attempt to make connections between the data and the conclusions evident.

Although the Berkenkotter, Huckin, and Ackerman (1988) study does not, case study reports often include the reactions of the participants to the study or to the researchers' conclusions. Because case studies tend to be exploratory, most end with implications for further study. Here researchers may identify significant variables that emerged during the research and suggest studies related to these, or the authors may suggest further general questions that their case study generated.

For example, Emig's (1971) study concludes with a section dedicated solely to the topic of implications for further research, in which she suggests several means by which this particular study could have been improved, as well as questions and ideas raised by this study which other researchers might like to address, such as: is there a correlation between a certain personality and a certain composing process profile (e.g. is there a positive correlation between ego strength and persistence in revising)?

Also included in Emig's study is a section dedicated to implications for teaching, which outlines the pedagogical ramifications of the study's findings for teachers currently involved in high school writing programs.

Sharan Merriam (1985) also offers several suggestions for alternative presentations of data:

• Prepare specialized condensations for appropriate groups.
• Replace narrative sections with a series of answers to open-ended questions.
• Present "skimmer's" summaries at beginning of each section.
• Incorporate headlines that encapsulate information from text.
• Prepare analytic summaries with supporting data appendixes.
• Present data in colorful and/or unique graphic representations.

Issues of Validity and Reliability

Once key variables have been identified, they can be analyzed. Reliability becomes a key concern at this stage, and many case study researchers go to great lengths to ensure that their interpretations of the data will be both reliable and valid. Because issues of validity and reliability are an important part of any study in the social sciences, it is important to identify some ways of dealing with results.

Multi-modal case study researchers often balance the results of their coding with data from interviews or writer's reflections upon their own work. Consequently, the researchers' conclusions become highly contextualized. For example, in a case study which looked at the time spent in different stages of the writing process, Berkenkotter concluded that her participant, Donald Murray, spent more time planning his essays than in other writing stages. The report of this case study is followed by Murray's reply, wherein he agrees with some of Berkenkotter's conclusions and disagrees with others.

As is the case with other research methodologies, issues of external validity, construct validity, and reliability need to be carefully considered.

Commentary on Case Studies

Researchers often debate the relative merits of particular methods, among them case study. In this section, we comment on two key issues. To read the commentaries, choose any of the items below:

Strengths and Weaknesses of Case Studies

Most case study advocates point out that case studies produce much more detailed information than what is available through a statistical analysis. Advocates will also hold that while statistical methods might be able to deal with situations where behavior is homogeneous and routine, case studies are needed to deal with creativity, innovation, and context. Detractors argue that case studies are difficult to generalize because of inherent subjectivity and because they are based on qualitative subjective data, generalizable only to a particular context.

Flexibility

The case study approach is a comparatively flexible method of scientific research. Because its project designs seem to emphasize exploration rather than prescription or prediction, researchers are comparatively freer to discover and address issues as they arise in their experiments. In addition, the looser format of case studies allows researchers to begin with broad questions and narrow their focus as their experiment progresses rather than attempt to predict every possible outcome before the experiment is conducted.

Emphasis on Context

By seeking to understand as much as possible about a single subject or small group of subjects, case studies specialize in "deep data," or "thick description"--information based on particular contexts that can give research results a more human face. This emphasis can help bridge the gap between abstract research and concrete practice by allowing researchers to compare their firsthand observations with the quantitative results obtained through other methods of research.

Inherent Subjectivity

"The case study has long been stereotyped as the weak sibling among social science methods," and is often criticized as being too subjective and even pseudo-scientific. Likewise, "investigators who do case studies are often regarded as having deviated from their academic disciplines, and their investigations as having insufficient precision (that is, quantification), objectivity and rigor" (Yin 1989). Opponents cite opportunities for subjectivity in the implementation, presentation, and evaluation of case study research. The approach relies on personal interpretation of data and inferences. Results may not be generalizable, are difficult to test for validity, and rarely offer a problem-solving prescription. Simply put, relying on one or a few subjects as a basis for cognitive extrapolations runs the risk of inferring too much from what might be circumstance.

High Investment

Case studies can involve learning more about the subjects being tested than most researchers would care to know--their educational background, emotional background, perceptions of themselves and their surroundings, their likes, dislikes, and so on. Because of its emphasis on "deep data," the case study is out of reach for many large-scale research projects which look at a subject pool in the tens of thousands. A budget request of $10,000 to examine 200 subjects sounds more efficient than a similar request to examine four subjects.

Ethical Considerations

Researchers conducting case studies should consider certain ethical issues. For example, many educational case studies are often financed by people who have, either directly or indirectly, power over both those being studied and those conducting the investigation (1985). This conflict of interests can hinder the credibility of the study.

The personal integrity, sensitivity, and possible prejudices and/or biases of the investigators need to be taken into consideration as well. Personal biases can creep into how the research is conducted, alternative research methods used, and the preparation of surveys and questionnaires.

A common complaint in case study research is that investigators change direction during the course of the study unaware that their original research design was inadequate for the revised investigation. Thus, the researchers leave unknown gaps and biases in the study. To avoid this, researchers should report preliminary findings so that the likelihood of bias will be reduced.

Concerns about Reliability, Validity, and Generalizability

Merriam (1985) offers several suggestions for how case study researchers might actively combat the popular attacks on the validity, reliability, and generalizability of case studies:

• Prolong the Processes of Data Gathering on Site: This will help to insure the accuracy of the findings by providing the researcher with more concrete information upon which to formulate interpretations.
• Employ the Process of "Triangulation": Use a variety of data sources as opposed to relying solely upon one avenue of observation. One example of such a data check would be what McClintock, Brannon, and Maynard (1985) refer to as a "case cluster method," that is, when a single unit within a larger case is randomly sampled, and that data treated quantitatively." For instance, in Emig's (1971) study, the case cluster method was employed, singling out the productivity of a single student named Lynn. This cluster profile included an advanced case history of the subject, specific examination and analysis of individual compositions and protocols, and extensive interview sessions. The seven remaining students were then compared with the case of Lynn, to ascertain if there are any shared, or unique dimensions to the composing process engaged in by these eight students.
• Conduct Member Checks: Initiate and maintain an active corroboration on the interpretation of data between the researcher and those who provided the data. In other words, talk to your subjects.
• Collect Referential Materials: Complement the file of materials from the actual site with additional document support. For example, Emig (1971) supports her initial propositions with historical accounts by writers such as T.S. Eliot, James Joyce, and D.H. Lawrence. Emig also cites examples of theoretical research done with regards to the creative process, as well as examples of empirical research dealing with the writing of adolescents. Specific attention is then given to the four stages description of the composing process delineated by Helmoltz, Wallas, and Cowley, as it serves as the focal point in this study.
• Engage in Peer Consultation: Prior to composing the final draft of the report, researchers should consult with colleagues in order to establish validity through pooled judgment.

Although little can be done to combat challenges concerning the generalizability of case studies, "most writers suggest that qualitative research should be judged as credible and confirmable as opposed to valid and reliable" (Merriam 1985). Likewise, it has been argued that "rather than transplanting statistical, quantitative notions of generalizability and thus finding qualitative research inadequate, it makes more sense to develop an understanding of generalization that is congruent with the basic characteristics of qualitative inquiry" (1985). After all, criticizing the case study method for being ungeneralizable is comparable to criticizing a washing machine for not being able to tell the correct time. In other words, it is unjust to criticize a method for not being able to do something which it was never originally designed to do in the first place.

"Increasingly, one of the most pressing questions for WAC advocates is how to keep [WAC] programs going in the face of numerous difficulties. Case histories offer the best chance for fashioning rhetorical arguments to keep WAC programs going because they offer the opportunity to provide a coherent narrative that contextualizes all documents and data, including what is generally considered scientific data. A case study of the WAC program, . . . at Robert Morris College in Pittsburgh demonstrates the advantages of this research method. Such studies are ideal homes for both naturalistic and positivistic data as well as both quantitative and qualitative information."

Data Gathering in 2024: Overview, Challenges & Methods

While our previous article focuses on AI data collection , this article explores gathering data for other use cases and purposes.

Organizations and researchers need to gather large volumes of data to fuel their projects. Due to this growing need for data, the interest in data gathering has grown over the past few years (Figure 2).

Figure 2: Rising interest in data gathering in the past few years

To help data-driven businesses streamline the process of gathering data, this article explores:

• What data gathering means
• Why businesses need to gather data
• How they can gather data for different use cases
• What are some challenges of collecting data and how a service provider can help overcome them.

What does data gathering mean?

Data gathering is the process of gathering data from different sources , such as human-generated content, websites, online surveys, customer feedback, social media posts , and ready-made datasets. The collected data is used for different processes, such as developing AI-powered solutions, conducting research, or other data-hungry tasks.

Top reasons/use cases for collecting data

Organizations gather data for various reasons. This section highlights some of the top reasons why businesses should gather data.

1. Train AI/ML solutions

Training AI/ML models involves gathering diverse data types based on learning modalities to create accurate models. This is one of the most popular use cases of data gathering as the adoption of AI grows. 

Suitable methods of gathering data

The gathering method depends on the type of AI application. For example, a self-driving car model needs vast quantities of images and videos of roads, pedestrians, and other vehicles. Collecting such data could involve using cameras mounted on vehicles or working with a crowdsourcing data collection service provider . In contrast, natural language processing applications may require textual data collected from diverse sources such as books, websites, and social media platforms.

2. Deploy AI/ML solutions

During AI model deployment, data is needed to test and validate the model’s performance. This requires the collection of fresh and unseen data to ensure the model generalizes properly to new situations. 

Suitable methods of gathering

A recommendation engine may require data on user preferences and behaviors, which can be collected through in-house data collection from customer data. However, deploying a facial recognition system necessitates gathering real-world images to verify the system’s accuracy. Using prepackaged image datasets can be helpful for this purpose.

3. Improve AI/ML solutions

Improving AI/ML models is necessary as performance degrades over time due to changing data and circumstances. This requires fresh data to be collected to retrain the model and improve its performance.

An AI-powered quality control system on a production line may require updated data when the product changes. This type of data can be collected internally from a PDM platform. 

On the other hand, if a machine translation model needs fresh text data to accommodate changes in language use, a more suitable method would be working with a data collection service provider.

4. Improve online marketing operations

Data needs to be gathered to improve online marketing processes.

• Research : Conducting online surveys to assess product user-friendliness, which can be done in-house or outsourced to third-party service providers. Click here to learn more about research data collection. 
• Sentiment Analysis: Evaluating customer attitudes through sentiment analysis data on social media feedback to identify keywords describing a brand.
• Personalization: Collecting user behavior data to create personalized content and recommendations, enhancing customer engagement and satisfaction.
• Market Analysis: Gathering market data to identify trends, competitor strategies, and emerging opportunities, informing decision-making and future marketing campaigns.

Different data gathering methods can optimize various aspects of online marketing. 

• Web analytics tools can gather data on user behavior.
• Surveys or interviews can be used for qualitative or quantitative research to understand user experiences
• Sentiment analysis, which involves collecting user feedback from social media, can help understand customer attitudes toward a brand or product. A data collection service that also offers sentiment analysis solutions can be a good fit for this use case.

5. Search engine optimization

SEO leverages data gathering for creating accurate, up-to-date product descriptions in various languages.

Keyword research is a crucial data gathering method that involves identifying popular search terms and incorporating them into the website’s content. Analyzing competitor websites, backlinks, and metadata can help refine SEO strategies, while user behavior data, such as bounce rates and session duration, can provide insights for website optimization. 

If dedicating a team is not possible for collecting data and implementing SEO-friendly practices, you can outsource the data collection process.

Data gathering challenges and how working with a service provider can help

Collecting data for your data-hungry processes can be challenging. However, working with a data gathering service provider can help overcome these challenges. 

1. Data quality and consistency

Ensuring high data quality and consistency is a primary challenge for companies during gathering data, especially for large-scale data gathering projects. Inaccurate or incomplete data can have a negative impact on the project.

 Nowadays, most data gathered is raw and unstructured and can be challenging to manage (Figure 3). Purchasing sophisticated analytics tools for unstructured data can be expensive. If you dedicate a team for the process, your employees will be spending a significant amount of time performing repetitive and error-prone data correction and structuring tasks.

How a data service provider can help

Data gathering services have quality control and data processing standards in place and can offer a scalable service based on your needs and budget. By partnering with a reliable service provider, organizations can access their expertise in curating accurate and consistent data sets. These service providers employ robust data validation and verification processes to ensure high-quality data, contributing to your data-driven projects.

Adhering to data privacy regulations, such as GDPR and CCPA, is a significant challenge for companies collecting data. Striking a balance between data gathering and privacy concerns is critical. If you dedicate a team to data gathering, it can be challenging for them to follow all data protection policies and regulations. 

You can transfer the burden of data privacy and compliance issues to a third party for a fee. Data gathering service providers are well-versed in regulatory requirements and can help businesses navigate data privacy and compliance concerns. By implementing data governance frameworks and employing techniques like anonymization and pseudonymization, these providers can help minimize privacy risks in gathering data.

3. Data volume and complexity

Handling the vast volume and complexity of data from diverse sources, like social media and IoT devices, is a daunting task for the development team.

How a data service provider can help 

A data collection service can utilize state-of-the-art big data tools or work with a crowdsourcing model to manage and process large volumes of complex data. By incorporating data management tools or working with a large community of data collectors and processors, they can efficiently handle unstructured data and provide ready-to-use datasets much faster.

4 Gathering and Analyzing Qualitative Data

Gathering and analyzing qualitative data.

As the role of clinician researchers expands beyond the bedside, it is important to consider the possibilities of inquiry beyond the quantitative approach. In contrast to the quantitative approach, qualitative methodology is highly inductive and relies on the background and interpretation of the researcher to derive meaning from the gathering and analytic processes central to qualitative inquiry.

Chapter 4: Learning Objectives

As you explore the research opportunities central to your interests to consider whether qualitative component would enrich your work, you’ll be able to:

• Define what qualitative research is
• Compare qualitative and quantitative approaches
• Describe the process of creating themes from recurring ideas gleaned from narrative interviews

What Is Qualitative Research?

Quantitative researchers typically start with a focused research question or hypothesis, collect a small amount of numerical data from a large number of individuals, describe the resulting data using statistical techniques, and draw general conclusions about some large population. Although this method is by far the most common approach to conducting empirical research in fields such as respiratory care and other clinical fields, there is an important alternative called qualitative research. Qualitative research originated in the disciplines of anthropology and sociology but is now used to study psychological topics as well. Qualitative researchers generally begin with a less focused research question, collect large amounts of relatively “unfiltered” data from a relatively small number of individuals, and describe their data using nonstatistical techniques, such as grounded theory, thematic analysis, critical discourse analysis, or interpretative phenomenological analysis. They are usually less concerned with drawing general conclusions about human behavior than with understanding in detail the experience of their research participants.

Consider, for example, a study by researcher Per Lindqvist and his colleagues, who wanted to learn how the families of teenage suicide victims cope with their loss (Lindqvist, Johansson, & Karlsson, 2008). They did not have a specific research question or hypothesis, such as, What percentage of family members join suicide support groups? Instead, they wanted to understand the variety of reactions that families had, with a focus on what it is like from their perspectives. To address this question, they interviewed the families of 10 teenage suicide victims in their homes in rural Sweden. The interviews were relatively unstructured, beginning with a general request for the families to talk about the victim and ending with an invitation to talk about anything else that they wanted to tell the interviewer. One of the most important themes that emerged from these interviews was that even as life returned to “normal,” the families continued to struggle with the question of why their loved one committed suicide. This struggle appeared to be especially difficult for families in which the suicide was most unexpected.

The Purpose of Qualitative Research

The strength of quantitative research is its ability to provide precise answers to specific research questions and to draw general conclusions about human behavior. This method is how we know that people have a strong tendency to obey authority figures, for example, and that female undergraduate students are not substantially more talkative than male undergraduate students. But while quantitative research is good at providing precise answers to specific research questions, it is not nearly as good at generating novel and interesting research questions. Likewise, while quantitative research is good at drawing general conclusions about human behavior, it is not nearly as good at providing detailed descriptions of the behavior of particular groups in particular situations. And quantitative research is not very good at communicating what it is actually like to be a member of a particular group in a particular situation.

But the relative weaknesses of quantitative research are the relative strengths of qualitative research. Qualitative research can help researchers to generate new and interesting research questions and hypotheses. The research of Lindqvist and colleagues, for example, suggests that there may be a general relationship between how unexpected a suicide is and how consumed the family is with trying to understand why the teen committed suicide. This relationship can now be explored using quantitative research. But it is unclear whether this question would have arisen at all without the researchers sitting down with the families and listening to what they themselves wanted to say about their experience. Qualitative research can also provide rich and detailed descriptions of human behavior in the real-world contexts in which it occurs. Among qualitative researchers, this depth is often referred to as “thick description” (Geertz, 1973) .

Similarly, qualitative research can convey a sense of what it is actually like to be a member of a particular group or in a particular situation—what qualitative researchers often refer to as the “lived experience” of the research participants. Lindqvist and colleagues, for example, describe how all the families spontaneously offered to show the interviewer the victim’s bedroom or the place where the suicide occurred—revealing the importance of these physical locations to the families. It seems unlikely that a quantitative study would have discovered this detail. The table below lists some contrasts between qualitative and quantitative research

Data Collection and Analysis in Qualitative Research

Data collection approaches in qualitative research are quite varied and can involve naturalistic observation, participant observation, archival data, artwork, and many other things. But one of the most common approaches, especially for psychological research, is to conduct interviews. Interviews in qualitative research can be unstructured—consisting of a small number of general questions or prompts that allow participants to talk about what is of interest to them—or structured, where there is a strict script that the interviewer does not deviate from. Most interviews are in between the two and are called semi-structured interviews, where the researcher has a few consistent questions and can follow up by asking more detailed questions about the topics that come up. Such interviews can be lengthy and detailed, but they are usually conducted with a relatively small sample. The unstructured interview was the approach used by Lindqvist and colleagues in their research on the families of suicide victims because the researchers were aware that how much was disclosed about such a sensitive topic should be led by the families, not by the researchers.

Another approach used in qualitative research involves small groups of people who participate together in interviews focused on a particular topic or issue, known as focus groups. The interaction among participants in a focus group can sometimes bring out more information than can be learned in a one- on-one interview. The use of focus groups has become a standard technique in business and industry among those who want to understand consumer tastes and preferences. The content of all focus group interviews is usually recorded and transcribed to facilitate later analyses. However, we know from social psychology that group dynamics are often at play in any group, including focus groups, and it is useful to be aware of those possibilities. For example, the desire to be liked by others can lead participants to provide inaccurate answers that they believe will be perceived favorably by the other participants. The same may be said for personality characteristics. For example, highly extraverted participants can sometimes dominate discussions within focus groups.

Data Analysis in Qualitative Research

Although quantitative and qualitative research generally differ along several important dimensions (e.g., the specificity of the research question, the type of data collected), it is the method of data analysis that distinguishes them more clearly than anything else. To illustrate this idea, imagine a team of researchers that conducts a series of unstructured interviews with people recovering from alcohol use disorder to learn about the role of their religious faith in their recovery. Although this project sounds like qualitative research, imagine further that once they collect the data, they code the data in terms of how often each participant mentions God (or a “higher power”), and they then use descriptive and inferential statistics to find out whether those who mention God more often are more successful in abstaining from alcohol. Now it sounds like quantitative research. In other words, the quantitative-qualitative distinction depends more on what researchers do with the data they have collected than with why or how they collected the data.

But what does qualitative data analysis look like? Just as there are many ways to collect data in qualitative research, there are many ways to analyze data. Here we focus on one general approach called grounded theory (Glaser & Strauss, 1967) . This approach was developed within the field of sociology in the 1960s and has gradually gained popularity in psychology. Remember that in quantitative research, it is typical for the researcher to start with a theory, derive a hypothesis from that theory, and then collect data to test that specific hypothesis. In qualitative research using grounded theory, researchers start with the data and develop a theory or an interpretation that is “grounded in” those data. They do this analysis in stages. First, they identify ideas that are repeated throughout the data. Then they organize these ideas into a smaller number of broader themes. Finally, they write a theoretical narrative—an interpretation of the data in terms of the themes that they have identified. This theoretical narrative focuses on the subjective experience of the participants and is usually supported by many direct quotations from the participants themselves.

As an example, consider a study by researchers Laura Abrams and Laura Curran, who used the grounded theory approach to study the experience of postpartum depression symptoms among low-income mothers (Abrams & Curran, 2009) . Their data were the result of unstructured interviews with 19 participants. The table below hows the five broad themes the researchers identified and the more specific repeating ideas that made up each of those themes. In their research report, they provide numerous quotations from their participants, such as this one from “Destiny:”

“Well, just recently my apartment was broken into and the fact that his Medicaid for some reason was cancelled so a lot of things was happening within the last two weeks all at one time. So that in itself I don’t want to say almost drove me mad but it put me in a funk….Like I really was depressed. (p. 357)”

Their theoretical narrative focused on the participants’ experience of their symptoms, not as an abstract “affective disorder” but as closely tied to the daily struggle of raising children alone under often difficult circumstances. The table below illustrates the process of creating themes from repeating ideas in the qualitative research gathering and analysis process.

Given their differences, it may come as no surprise that quantitative and qualitative research do not coexist in complete harmony. Some quantitative researchers criticize qualitative methods on the grounds that they lack objectivity, are difficult to evaluate in terms of reliability and validity, and do not allow generalization to people or situations other than those actually studied. At the same time, some qualitative researchers criticize quantitative methods on the grounds that they overlook the richness of human behavior and experience and instead answer simple questions about easily quantifiable variables.

In general, however, qualitative researchers are well aware of the issues of objectivity, reliability, validity, and generalizability. In fact, they have developed a number of frameworks for addressing these issues (which are beyond the scope of our discussion). And in general, quantitative researchers are well aware of the issue of oversimplification. They do not believe that all human behavior and experience can be adequately described in terms of a small number of variables and the statistical relationships among them. Instead, they use simplification as a strategy for uncovering general principles of human behavior.

Many researchers from both the quantitative and qualitative camps now agree that the two approaches can and should be combined into what has come to be called mixed-methods research (Todd, Nerlich, McKeown, & Clarke, 2004). In fact, the studies by Lindqvist and colleagues and by Abrams and Curran both combined quantitative and qualitative approaches. One approach to combining quantitative and qualitative research is to use qualitative research for hypothesis generation and quantitative research for hypothesis testing. Again, while a qualitative study might suggest that families who experience an unexpected suicide have more difficulty resolving the question of why, a well-designed quantitative study could test a hypothesis by measuring these specific variables in a large sample. A second approach to combining quantitative and qualitative research is referred to as triangulation. The idea is to use both quantitative and qualitative methods simultaneously to study the same general questions and to compare the results. If the results of the quantitative and qualitative methods converge on the same general conclusion, they reinforce and enrich each other. If the results diverge, then they suggest an interesting new question: Why do the results diverge and how can they be reconciled?

Using qualitative research can often help clarify quantitative results via triangulation. Trenor, Yu, Waight, Zerda, and Sha (2008) investigated the experience of female engineering students at a university. In the first phase, female engineering students were asked to complete a survey, where they rated a number of their perceptions, including their sense of belonging. Their results were compared across the student ethnicities, and statistically, the various ethnic groups showed no differences in their ratings of their sense of belonging.

One might look at that result and conclude that ethnicity does not have anything to do with one’s sense of belonging. However, in the second phase, the authors also conducted interviews with the students, and in those interviews, many minority students reported how the diversity of cultures at the university enhanced their sense of belonging. Without the qualitative component, we might have drawn the wrong conclusion about the quantitative results.

This example shows how qualitative and quantitative research work together to help us understand human behavior. Some researchers have characterized qualitative research as best for identifying behaviors or the phenomenon whereas quantitative research is best for understanding meaning or identifying the mechanism. However, Bryman (2012) argues for breaking down the divide between these arbitrarily different ways of investigating the same questions.

Key Takeaways

• The qualitative approach is centered on an inductive method of reasoning
• The qualitative approach focuses on understanding phenomenon through the perspective of those experiencing it
• Researchers search for recurring topics and group themes to build upon theory to explain findings
• A mixed methods approach uses both quantitative and qualitative methods to explain different aspects of a phenomenon, processes, or practice

How to gather information for case studies.

There is another method of gathering information which is relevant and must be described. It is called case studies and it is the most adjustable of all research designs. At the level that is the simplest, they give descriptive accounts of the case.

Gathering Information For Case Study Research

The subject of case studies is considered to be one or more examples of social existence, such as:

• Communities
• Organizations
• Life histories
• Relationships

How to Write a Case Study

After the topic of the research is defined, selective case studies can concentrate on particular aspects to refine information. At the level that is the most rigorous;

• Case studies are created to reach experimental isolation of the chosen social factors or processes within a context of the real life in order to conduct a test of predominant explanations and ideas.
• Case study research is connected with receiving a roundish picture of a situation from the perspectives of all involved into research people, usually applying a number of methods.
• Case studies are usually grounded on two or more methods of gathering information. Using multiple evidence lets case studies provide more roundish and full accounts of social processes.

Applying multiple sources of evidence and investigators when the case study either descriptive or explanatory makes it one of the most powerful research designs.

• This research design is the preferable strategy when why or how questions are being asked, when the researcher has not much control over situation and when a contemporary phenomenon is being focused on.
• Case studies are  apt when there are no clearly confirmed boundaries between the phenomenon and the context.
• The case study manages the technically distinctive situation in which there will appear more variables of interest information points, and as one result depends on multiple source of proof, with information needing to combine in a triangulating fashion.
