Answer:
Case study
Explanation:
A case study is a kind of study used in social sciences in which the researcher observes an individual/group/event in a very in-depth manner. Case studies give a lot of information about the person or group who is being studied and let the researcher make causal inferences (because of the in-depth observation) and the researcher gets a better understanding of the situation.
