Which concept refers to a special case that may highlight things related to most non-special cases?

Which concept refers to a special case that may highlight things related to most non-special cases?

• A. Critical Cases
• B. Benefit of Larger Samples
• C. Self-Selecting Sample
• D. Snowball Sampling

Answer: (A)

Critical cases are selected because they are especially informative for testing how a phenomenon operates in relation to a theory across a wider range of situations. By focusing on a case that is extreme, unusual, or particularly revealing, researchers can see whether the theory holds under conditions that matter most for typical, non-special cases. If the idea explains or predicts what happens in this important case, it strengthens the case that it will apply more broadly to ordinary situations. If it fails here, it signals a need to rethink or refine the theory. In contrast, larger samples, self-selected samples, and snowball sampling address who is included or how participants are recruited, not the strategic choice of a case that sharpens understanding of patterns likely to appear in most non-special cases.
