Internal validity is concerned with the accuracy of the causal relationship between the independent and dependent variables within a study. Generalization, on the other hand, refers to the ability to extend findings from a particular sample or setting to a broader population. Maturation, experimental mortality, statistical regression, and interaction of pretest and treatment are all factors that can potentially threaten the internal validity of a study by introducing alternative explanations for the observed results.
