Question

Quizplus · Accepted Answer

The internal validity problem that may occur is diffusion of treatment, where subjects from different groups may share information about what they are reading and thus affect the results of the experiment. This could potentially invalidate the results because the control group may become aware of the purpose of the study through interaction with the experimental group, leading to contamination of the control group.
