B) ABA
C) AB
D) ALIBABA

Question

Quizplus · Accepted Answer

A single subject reversal design is typically represented as a repeated sequence of phases, where an intervention is introduced during one phase (A), removed during a subsequent phase (B), and then reintroduced during a final phase (A). This is typically abbreviated as an ABA design, which represents the order of the phases. Option A (ABACA) represents an ABA design with an extra phase in between the two A phases, which is not standard for a single subject reversal design. Option C (AB) only includes one reversal, which is not a true reversal design as it does not include a second intervention phase. Option D (ALIBABA) is not a standard notation for any type of experimental design.
