Quizplus · Accepted Answer

External validity refers to the extent to which the results of an experiment can be generalized to the larger population. This is the aspect of validity that directly addresses the question asked in the prompt. Internal validity refers to the extent to which the experiment was designed and executed correctly to support causal conclusions. Reliability refers to the consistency of results over time and across different researchers. Statistical significance refers to the likelihood that the observed differences between groups are due to chance. Substantive significance refers to the practical or real-world importance of the observed differences. Although all of these aspects of validity are important to consider, external validity is the most directly relevant to answering the prompt.
