Case study refers to the collection and presentation of detailed information about a particular participant or small group, frequently including the accounts of subjects themselves. The case study looks at an individual or small participant pool, drawing conclusions only about that participant or group and only in that specific context. Researchers do not focus on the discovery of a generalizable truth, and they do not usually look for cause-effect relationships. These case studies often appear in research journals and professional conferences, rather than popular works. Why might a scientist choose to do a case study instead of a controlled, laboratory experiment? A) Case study results can always be generalized to the wider population. B) Case studies are always more accurate that other methods of experimentation. C) Anyone can do a case study where you must have a college degree in science to do lab experiments. D) Case studies are conducted in rare cases where large samples of similar participants are not available.
