Question

Quizplus · Accepted Answer

Meta-analysis is a statistical technique that combines the results of multiple studies to establish the consistency of an effect across past studies and estimate the average effect size. This is important in addressing the problem of external validity, which refers to the generalizability of research findings to other populations and settings beyond the ones studied. By synthesizing the results of multiple studies, meta-analysis can provide a more comprehensive and accurate picture of the magnitude and robustness of an effect, which can enhance the external validity of research findings.
