Which statement is true about case studies and single-subject designs?

Question

Quizplus · Accepted Answer

Single-subject designs typically have more internal validity because they allow for the control and manipulation of variables, and the observation of effects on the same subjects over time. This design often includes baseline measurements, interventions, and follow-up observations, which help to establish a cause-and-effect relationship more clearly than case studies, which are more descriptive and exploratory in nature.
