A detailed in-depth study of one group or event is called a:

• A. Case study
• B. Longitudinal survey
• C. Focus group
• D. Group interview

Answer: (A)

The main idea being tested is a case study, a research approach that focuses on an in-depth, holistic investigation of a single group or event within its real-life context. Case studies gather rich, detailed data from multiple sources—interviews, observations, documents—to build a thick description of how the group operates, why events unfold as they do, and how different factors interact. This depth and contextual understanding set it apart from methods that aim for breadth or general patterns. A longitudinal survey follows the same group over time with repeated measurements, emphasizing changes and trends rather than an intimate look at one case. A focus group explores ideas through a facilitated group discussion, not an in-depth analysis of one specific case. A group interview collects views from several people at once but, again, isn’t centered on an intensive single case. So, for an in-depth study of one group or event, a case study is the best fit.
