When You Employ the BC Design, You Engage in the Same

When you employ the BC design, you engage in the same statistical analysis procedures as with the AB design, except that:

A) the first treatment line and the second treatment are treated as the treatment phases
B) the second treatment phase is treated as the baseline phase
C) the analysis answers the question of whether the first treatment is more effective than the second
D) the first treatment phase is treated as the baseline phase and the second treatment phase is treated as the treatment phase
