Quizplus · Accepted Answer

Internal validity refers to the accuracy and strength of the cause-and-effect relationship established by a study, while external validity refers to the generalizability of the findings to other settings or populations. While both are important, internal validity is necessary to ensure that the intervention or treatment actually caused the observed outcomes. Therefore, internal validity is more critical for making evidence-based decisions about the effectiveness of an intervention in a particular context or population.
