Question

Quizplus · Accepted Answer

External validity refers to the generalizability of research findings to other settings, populations, and conditions outside of the original study. Repetition in different circumstances helps establish external validity by demonstrating that the findings hold up under different conditions and with different groups, increasing the generalizability of the results. Analogue experiments, random assignment to control groups, and double-blind procedures are not directly related to establishing external validity.
