What best describes a case study in research?

A case study in research refers to an in-depth investigation of a single individual, group, or event. This approach allows researchers to explore the complexities and nuances of the subject matter. By focusing on a specific case, researchers can gather detailed qualitative and quantitative data that provides insights into the broader context surrounding the subject. This methodology is particularly valuable when examining unique or intricate phenomena that wouldn't be adequately captured through larger quantitative studies.

Additionally, case studies can illuminate patterns, generate hypotheses, and establish a rich narrative that might not emerge from other research formats. The depth of investigation lends itself to a more holistic understanding of the issue being studied, making it a powerful method in fields such as psychology, sociology, and education.
