Which term refers to a detailed analysis of a person or group as a model for various phenomena?

The term that refers to a detailed analysis of a person or group as a model for various phenomena is a case study. A case study involves in-depth investigation and examination of a specific instance, individual, or group, often aimed at understanding complex issues, behaviors, or conditions in real-world contexts. This method is particularly valuable in fields like psychology, medicine, and social sciences, where individual or small group dynamics provide insights that can be generalized to broader populations or issues.

In contrast, intervention refers to actions taken to improve a situation, especially in a health or social context, while pedigree pertains to the recorded ancestry or lineage of an individual, often used in genetics to trace traits through generations. Pathogen relates to microorganisms that can cause disease, which does not apply to the idea of analysis or modeling phenomena. Thus, a case study is best suited to describe the detailed examination of individuals or groups for research or educational purposes.
