[1] [2] For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time like the operations of a ...
Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion. [2] Like other research methodologies within psychology, the case study must produce valid and reliable results in order to be useful for the development of future research.
A case–control study (also known as case–referent study) is a type of observational study in which two existing groups differing in outcome are identified and compared on the basis of some supposed causal attribute. Case–control studies are often used to identify factors that may contribute to a medical condition by comparing subjects who ...

Case series may be consecutive[ 2] or non-consecutive, [ 3] depending on whether all ...
The case study method exemplifies qualitative researchers' preference for depth, detail, and context. [12] [13] Data triangulation is also a strategy used in qualitative research. [14] Autoethnography, the study of self, is a qualitative research method in which the researcher uses his or her personal experience to understand an issue.
The case method is a teaching approach that uses decision-forcing cases to put students in the role of people who were faced with difficult decisions at some point in the past. It developed during the course of the twentieth-century from its origins in the casebook method of teaching law pioneered by Harvard legal scholar Christopher C. Langdell.

Case reports may contain a demographic profile of the patient, but usually describe an unusual or novel occurrence. Some case reports also contain a literature review of other reported cases.
