Quizplus · Accepted Answer

Internal invalidity refers to the possibility that the experimental stimulus did not actually affect the dependent variable, which could be caused by confounding variables, selection bias, or other issues related to the study's design. The other answer choices are related to different aspects of the study's design or implementation, but do not directly address the question of whether the experimental manipulation was responsible for the observed results.
