Meta-analysis is a statistical technique that allows researchers to synthesize the results of multiple studies in order to draw more robust and generalizable conclusions. It takes into account sample size and the magnitude and consistency of differences, which simple reviews of studies may not attend to. Additionally, meta-analysis can be used to explore moderator variables, such as differences in study population, methods, or setting, that may influence the results. Therefore, all the above options are correct.
