Often, a case study is a way for a researcher to learn more about a specific topic. In this type of research, the subject of interest is the problem or phenomenon that the researcher wishes to study. However, some types of case studies do not have a specific subject. These studies can be conducted in any field and are commonly used in educational research. This type of research allows for a more thorough investigation of an issue. A case study can be written in a variety of styles. The purpose of the research is to gain an in-depth understanding of the case and bring together all relevant aspects. The writing style of the case study will depend on the type of research being conducted. Some are structured like a standard scientific paper, with separate sections for methods, results, and discussion. Others are written in a more narrative style, focusing on the meaning of the experience. 

Case studies are typically written as a report, and they aim to provide a detailed understanding of the particular case. Because of ethical considerations, they must not be too detailed. However, a brief description of all participants and their roles must be included.

The research questions used for case studies should be based on theory and the existing literature. 

For instance, in an investigation of social policy or health, a researcher may focus on the issues that are relevant for the specific context. In a case study, the research question should be informed by the setting in which the case was undertaken. For example, if the study is done to find a solution to a problem, the research question should be able to be answered using a single, concrete case, rather than a large, generalized population.
