Quizplus · Accepted Answer

The design Bryce employed is a B-A-B design, which involves a baseline phase (B), an intervention phase (A), and a return to baseline phase (B). This type of design allows for the evaluation of the effects of the intervention by comparing the data collected during the intervention phase to the baseline data. The discontinuation of the intervention and the subsequent return to baseline also provide evidence for the effectiveness of the intervention.
