The question about whether the change in the dependent variable was really due to the treatment measures the internal validity of the design. This is because internal validity refers to the extent to which a study accurately reflects the effect of the independent variable on the dependent variable, without any outside factors or confounding variables influencing the results. Evaluating whether the treatment actually caused the change in the dependent variable is essential to ensuring the internal validity of a study.
