Question

Quizplus · Accepted Answer

External validity refers to the extent to which the results of a study can be generalized to other populations or situations. If the specific characteristics of the participants in a study are not representative of the larger population, it may limit the external validity of the study's results. Therefore, choosing the right sample and recruitment method is important for ensuring external validity. Random assignment and control are related to internal validity, which refers to the degree to which a study accurately reflects the relationship being studied, rather than confounding factors. While important, these factors are not directly related to the limitation of external validity discussed in the question.
