What is the chief advantage of an A-B-A-B design over a simpler A-B design, assuming the independent and dependent variables are the same as well as the subject, setting, and so on?

Fill in the blank(s) with the appropriate word(s).


Suggested answer points:An A-B-A-B design offers a replication of the original intervention effect found in a simpler A-B design. That is, the researcher is able to demonstrate the functional relationship between the independent and dependent variable twice (A1-B1-A2-B2) versus only the once in the A-B design.
