The major limitation of case studies is ______________. a. the superficial nature of the information collected in this approach b. the lack of control that the researcher has in this approach c. the inability to generalize the findings from this approach to the larger population d. the absence of inter-rater reliability

Case studies are in-depth investigations of a single person, group, event or community. Typically, data are gathered from a variety of sources and by using several different methods.

Now professional need to understand each option:a) Case studies, being in-depth, are normally not superficial in nature. So option (a) can be ruled out.b) Lack of control might be present in case studies, where researchers cannot possibly control all variables or events. c) The third option refers to the inability to generalize findings from a case study to the larger population, which is indeed a limitation, since case studies focus on individual or small group phenomena.d) Inter-rater reliability is a measure of reliability used to assess the degree to which different raters agree in their assessment decisions. While this might be a limitation in some studies, it is not a key limitation of case studies constraint specifically.

Based on the evaluation of options, it can be seen that option c is the major limitation of case studies.
