Question

Quizplus · Accepted Answer

The threat to internal validity illustrated in this example is selection-maturation interaction, as the experimental group may have been naturally predisposed to a higher learning/growth rate even before the experiment began. This makes it difficult to attribute the observed difference in learning/growth rate solely to the experimental treatment.
