Question

Quizplus · Accepted Answer

An ABAB design involves alternating between a baseline phase and an intervention phase, with a reversal back to the baseline phase before implementing the intervention again. A within-subjects experimental design with more than one participant can use different designs, including ABAB, but is not inherently similar or dissimilar to an ABAB design. A reversal design is similar to an ABAB design as it involves alternating between intervention and baseline phases, but with multiple reversals. An ABABA design is similar to an ABAB design, but includes an additional intervention phase before the final baseline phase. A case study is a type of observational research that does not involve any experimental manipulation and is dissimilar to an ABAB design.
