Quizplus · Accepted Answer

High internal validity means that the study was well-designed to control for confounding factors and establish causality within the sample studied, while medium external validity means that the results may not generalize well to other populations or settings. While external validity is important, a study with high internal validity provides stronger evidence for a causal relationship between the exposure and outcome being studied.
