The case study research design have evolved over the past few years as a useful tool for investigating trends and specific situations in many scientific disciplines. The case study has been especially used in social science, psychology, anthropology and ecology. This method of study is especially useful for trying to test theoretical models by using them in real world situations. For example, if an anthropologist were to live amongst a remote tribe, whilst their observations might produce no quantitative data, they are still useful to science. Basically, a case study is an in depth study of a particular situation rather than a sweeping statistical survey. It is a method used to narrow down a very broad field of research into one easily researchable topic.

A case study involves an up-close, in-depth, and detailed examination of a particular case or cases, within a real-world context. Generally, a case study can highlight nearly any individual, group, organization, event, belief system, or action. Case study research has been extensively practiced in both the social and natural sciences. As with other social science methods, no single research design dominates case study research. Case studies can use at least four types of designs. First, there may be a "no theory first" type of case study design, which is closely connected to Kathleen M. Eisenhardt 's methodological work.

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. A case—control study produces only an odds ratio, which is an inferior measure of strength of association compared to relative risk. The case—control is a type of epidemiological observational study. An observational study is a study in which subjects are not randomized to the exposed or unexposed groups, rather the subjects are observed in order to determine both their exposure and their outcome status and the exposure status is thus not determined by the researcher.
