Examples of a case study could be anything from researching why a single subject has nightmares when they sleep in their new apartment, to why a group of people feel uncomfortable in heavily populated areas. A case study is an in-depth analysis of a person or group of people.
Case studies are usually conducted over a sustained period of time, and they involve various forms of research, such as: observation, tests, examinations and even interviews. Case studies are used in a variety of social and life sciences, and the type of study that is conducted varies greatly depending on the field of science used.
Case studies are usually broken down into categories. For example, the illustrative case studies are based on the instance or instances of a particular event that describes what a situation is like. An example of one of these studies would be children fearing the doctor at a young age.
Another type of case study is the cumulative study that collects information from several places over the course of different times. These types of studies attempt to reduce repetitive research and focus on gathering information from the past to reach a conclusion. An example of this case study could be something along the lines of pre-existing behaviors in a creature throughout the course of various situations.
