Meta Analysis

Meta Analysis (pronounced: /ˈmɛtə əˈnælɪsɪs/) is a statistical technique used in medicine, psychology, sociology, and other fields to combine the results of multiple studies. The goal is to increase statistical power, improve estimates of the size of the effect, and/or resolve uncertainty when reports disagree.

Etymology

The term "Meta Analysis" was coined in 1976 by the statistician Gene V. Glass, who stated "my major interest currently is in what we have come to call...the meta-analysis of research. The term is a bit grand, but it is precise and apt... Meta-analysis refers to the analysis of analyses".
