What are the types of case studies?
Though case studies can be classified in many ways, the most common types are intrinsic, instrumental, and collective case studies.
Intrinsic case studies focus on a specific subject (i.e., case). The point of such studies is to learn more about this specific subject rather than to generalize findings.
Instrumental case studies also focus on a single subject, but the intent is to generalize findings to a broader population.
Collective case studies have the same purpose as instrumental case studies—to use findings to increase one’s understanding of a broader topic—but they include multiple cases.
