In an ABA reversal design, we are given a compelling demonstration that the independent variable is responsible for the change in the dependent variable when

A) there is no reversal.
B) the behavior changes in the predicted direction each time the reversal occurs.
C) the behavior changes in no particular direction at each measurement instance.
D) the behavior stays the same each time the reversal occurs.

Question 2

When using an ABA design, if you find that the behavior (the dependent measure) changes in the predicted direction, increasing or decreasing each time the reversal occurs, then

A) you have a compelling demonstration that the dependent measure is unreliable and should be changed.
B) you should consider the possibility that the dependent variable is not constant and is causing the fluctuations.
C) you have a compelling demonstration that the independent variable, and not some confounding variable, has affected the dependent variable.
D) you have shown that confounding variables, and not the independent variable, has affected the dependent variable.
