How do case studies and single-case designs differ?

Question

Quizplus · Accepted Answer

Case studies often involve detailed examination of a single subject or a small group without employing the rigorous control methods found in single-case experimental designs. This lack of control makes it harder to draw internally valid inferences from case studies compared to single-case designs, which are structured to test hypotheses about cause and effect by manipulating variables and observing the outcomes on single subjects or units under controlled conditions.
