Why can you argue that single-case designs are both strong and weak in external validity?
What will be an ideal response?
Case studies are strong in external validity because they involve studying people in natural settings, not in an artificial situation like a laboratory. Thus, from the point of view of mundane reality, case studies are strong. On the other hand, they are weak in external validity from the standpoint of generalizability. It is not clear whether the results from a study of a single person will generalize to other people in other situations.
