The results of a case study are not generally applicable.

Explanation:

A case study is a methodology within social science that focuses on one particular case. This methodology presents both advantages and disadvantages that are related with the results. Because the researcher concentrates solely on one case, the results can have a lot of depth and the researcher can have a deeper comprehension of it.

However, the results are also very particular, responding to the social, economical and political context as well as characteristics that are unique to that one case. Therefore, the researcher must make explicit that the results are not generally applicable to other cases.
