A case study is an in-depth examination of a particular case or cases within a real-world context. It can focus on nearly any individual, group, organization, event, belief system, or action. Case studies can be used to generate an in-depth, multi-faceted understanding of a complex issue in its real-life context. They can be qualitative or quantitative, and they can involve a small number of observations (a small N) or many observations (one or multiple individuals and entities across multiple time periods, all within the same case study) . Case studies have been extensively practiced in both the social and natural sciences.
Some key features of a case study include:
-
Research methodology: Case studies are research methodologies that examine subjects, projects, or organizations to tell a story. Research is a necessary part of every case study, and specific research fields are required to create studies.
-
Comprehensive examination: Case studies involve a comprehensive examination of a phenomenon and its context.
-
Real-world context: Case studies are conducted in a real-world context.
-
In-depth investigation: Case studies involve an intensive, systematic investigation of a single individual, group, community, or some other unit in which the researcher examines in-depth data relating to several variables.
-
Holistic nature: Case studies can address the holistic nature of a phenomenon, such as nursing care.
Case studies can be used in numerous sectors, such as social sciences, social work, psychology, healthcare, education, and marketing. They can be used to explain, describe, or explore events or phenomena in everyday contexts.
