Quizplus · Accepted Answer

The A-B-A-B design involves establishing a baseline (A), introducing an intervention (B), removing the intervention to return to baseline conditions (A), and then reintroducing the intervention (B), allowing for the observation of changes in the dependent variable with each phase. This design helps to demonstrate the effect of the intervention more clearly by showing that changes in the dependent variable are contingent on the presence of the intervention.
