What is Meta-Analysis?
Gene V. Glass (1976) introduced the term meta-analysis to refer to “the statistical analysis of a large collection of analysis results from individual studies for the purpose of integrating the findings” (p. 3). This set of statistical techniques has grown in popularity, and meta-analysis is now the standard tool for providing transparent, objective, and replicable summaries of research findings in the social sciences, medicine, education, and other fields (Hunt, 1997).
