Quizplus · Accepted Answer

An A-B-A-B design involves establishing a baseline (A), introducing the intervention (B), removing the intervention (A), and then reintroducing the intervention (B) while measuring the dependent variable each time. This design allows for the evaluation of the effectiveness of the intervention by comparing the dependent variable during the baseline phase to the dependent variable during the intervention phases. It also allows for the evaluation of the stability of the dependent variable when the intervention is removed.
