what is a case study

A case study is a report about a person, group, or situation that has been studied. If the case study, for instance, is about a group, it describes the behavior of the group as a whole, not the behavior of each individual in the group.

Case studies can be produced by following a formal research method. These case studies are likely to appear in formal research venues, as journals and professional conferences, rather than popular works. The resulting body of ‘case study research’ has long had a prominent place in many disciplines and professions, ranging from psychology, anthropology, sociology, and political science to education, clinical science, social work, and administrative science

In doing case study research, the “case” being studied may be an individual, organization, event, or action, existing in a specific time and place. For instance, clinical science has produced both well-known case studies of individuals and also case studies of clinical practices. However, when “case” is used in an abstract sense, as in a claim, a proposition, or an argument, such a case can be the subject of many research methods, not just case study research. Case studies may involve both qualitative and quantitative research methods.

Case studies in research may be mistaken for the case method used in teaching.
