What is a case study used for in research?

A case study is primarily employed in research to gain deeper insights about broader principles, theories, or phenomena by examining a specific instance in detail. This approach allows researchers to explore complex issues in context, taking into account multiple variables and real-life situations that might not be captured through purely quantitative methods.

When researchers conduct a case study, they delve into the nuances and intricacies of the subject, whether it be an individual, group, organization, or event. This depth of analysis can reveal patterns and insights that contribute to a larger understanding of the subject matter, making it particularly useful for exploratory research where the objective is to develop theories or generate ideas rather than simply confirm pre-existing hypotheses.

Other methods mentioned may not achieve this same level of detailed understanding. Analyzing statistical data focuses on quantifiable measures rather than contextual understanding. Testing a hypothesis typically involves more structured approaches like experiments, while surveying a large population seeks broad trends rather than deep insights. Thus, the case study's unique approach allows for a rich exploration of singular examples that can illuminate wider principles and findings in research.
