A case study is a research method that involves an in-depth analysis of a specific subject, such as an individual, group, organization, or event. It aims to explore complex issues in real-life contexts, providing detailed insights and understanding. Case studies are commonly used in various fields, including business, psychology, and education, to illustrate theories or practices. Typically, a case study includes background information, data collection, and analysis of the findings. Researchers may use interviews, observations, and documents to gather information. The results can help identify patterns, inform decision-making, and contribute to the development of new strategies or solutions in similar situations.
