By Tayyaba Rehman — Published on November 22, 2023
A case study is an in-depth analysis of a specific instance or subject. Research is a systematic inquiry to discover or verify information. Both methods are used to gain knowledge, but they differ in scope and approach.
Case Study vs. Research — What's the Difference?

Difference Between Case Study and Research


Key Differences

A Case Study is a methodological approach that involves a deep, comprehensive examination of a specific subject or instance, often in the context of its real-life setting. On the other hand, Research is a broader concept that encompasses systematic investigations to establish facts, principles, or generalizable knowledge.
Case Studies often rely on qualitative data, such as interviews, observations, or documents, to gain detailed insights into the subject matter. Research, depending on its type, can employ either qualitative or quantitative methods, or a combination of both, to address specific questions or hypotheses.
One of the key strengths of a Case Study is its ability to provide rich, contextual analyses, making it ideal for exploratory or explanatory purposes. In contrast, Research seeks to validate or challenge existing theories, develop new ones, or establish general truths through replicable methods.
Case Studies are often employed when a researcher wants to gain a deep understanding of a particular phenomenon, especially when it's complex or multifaceted. Research, being a more overarching term, can include various methodologies, including experiments, surveys, or observational studies, each suited for different objectives.
In summation, while both Case Study and Research aim to contribute to knowledge, the former does so by delving deeply into specific instances, and the latter by adopting a systematic approach to inquiry, which can be either broad or narrow in scope.

Common Curiosities

Is a case study a type of research?

Yes, a case study is a specific research methodology used to explore and analyze a particular instance or subject.

Why are case studies often used in business schools?

Case studies provide real-world examples, allowing students to apply theoretical knowledge in practical scenarios.

Can a research project include multiple case studies?

Yes, some research projects employ multiple case studies to provide a comprehensive understanding of a phenomenon.

Are case studies less valuable than other research methods?

No, case studies offer detailed insights that other methods might miss. Their value depends on the research question.

Why is research important in academia?

Research contributes to knowledge, challenges or validates theories, and fosters academic growth.

What is the primary difference between case study and research?

A case study offers in-depth insights into a specific instance, while research is a broader systematic inquiry into a subject.

Can research be both qualitative and quantitative?

Absolutely, research can employ qualitative methods, quantitative methods, or a mix of both.

Which method is more generalizable, case study or research?

Broad research methodologies, especially quantitative ones, often aim for generalizability, whereas case studies focus on specific instances.

Can a case study be considered empirical research?

Yes, if it's based on observed and measured phenomena and derives knowledge from actual experience.

Is all research experimental?

No, research can be experimental, observational, descriptive, or analytical, among other types.

Is it necessary for research to have a hypothesis?

Not always. While many research studies begin with a hypothesis, exploratory research might not.

Can a case study be quantitative?

While typically qualitative, case studies can incorporate quantitative data for a holistic view.

What makes a case study credible?

Credibility in a case study arises from thorough data collection, triangulation, and a clear presentation of findings.

Can research findings change over time?

Yes, as new information emerges and methodologies evolve, research conclusions can change.

How long should a case study be?

A case study's length varies based on its purpose, depth, and the medium (e.g., journal article vs. book).
