The experimenter has demonstrated external validity, which refers to the extent to which the findings of a study can be generalized to other populations or settings. By replicating the study with a different participant sample and obtaining similar results, the experimenter has shown that the findings are not limited to just one specific group of individuals, but can be applied more broadly. Internal validity (A) refers to the extent to which a study is free from confounds or alternative explanations for the results. Population consistency (C) is not a commonly used term in psychological research, and chronological consistency (D) is not relevant to this scenario.
