Which of the following is a difference between ABABdesigns and multiple-baseline designs?
a. ABAB designs have a maximum of two intervention phases, whereas in multiple-baseline designs,the intervention phases are applied to different dependent measures simultaneously.
b. ABAB designs identify causal relationships by withdrawing the intervention and reversing the change, whereas multiple-baseline designs determine causality by identifying changes in some but not all of the multiple dependent measures.
c. ABABdesigns involve the use of multiple criterion variables, whereas multiple-baseline designs involve the use of multiple predictor variables.
d. ABAB designs are free of threats to internal validity, whereas in multiple-baseline designs, there is a possibility of threat to internal validity even if the dependent variables are mutually independent.
