What is a case study in research methods?

A case study is a research method that involves an in-depth investigation of a specific individual, group, event, or community. It allows researchers to explore complex phenomena within their real-life context, providing rich qualitative data that can lead to a deeper understanding of the subject matter. This approach is particularly valuable in fields where capturing detailed nuances is essential, such as psychology, sociology, and anthropology.

In a case study, the researcher typically gathers information through various means, such as interviews, observations, and documents. The focus is on the detailed analysis of a particular case to uncover patterns, insights, and relationships that may not be apparent through more quantitative research methods. This depth of investigation can illuminate the complexities and dynamics involved in the subject.

The other options represent different research methods that are not focused on in-depth investigation. For example, statistical analysis pertains to the examination of numerical data drawn from large populations, while surveys are used to collect data from diverse groups generally without the exhaustive detail characteristic of case studies. Additionally, a brief overview of research findings does not capture the essence of what a case study entails.
