Both groups of children were tested for hyperactivity before and after taking the drug, which represented the second independent variable. The results indicated that the hyperactive children were less hyperactive after taking the drug than before taking the drug; the non-hyperactive children, however, were more hyperactive after taking the drug than before taking the drug. This type of a result is referred to as a(n)
a. main effect.
