Question

Quizplus · Accepted Answer

Meta-analysis is a statistical technique that combines results from multiple studies to increase the sample size and to produce a more accurate and precise estimate of the effect size. It can be used to identify patterns, relationships, and trends across studies, and to provide a comprehensive and systematic summary of the existing evidence on a particular topic or intervention. While meta-analysis can also be used to determine statistical significance and to assess the probability of chance affecting the results, its primary purpose is to synthesize and integrate findings from multiple studies in a quantitative and objective manner, thereby enhancing the validity and generalizability of the conclusions. Ethical standards in research are unrelated to the application of meta-analysis.
