Meta-analysis (also known as research synthesis or a quantitative literature review) is a research methodology in which one statistically compares and/or combines the results (effects sizes) of empirical studies that have been completed in a particular research domain. This 3-hour methodology workshop will include basic theoretical and application issues of meta-analysis; at the conclusion of this workshop, it is expected that the attendee will have sufficient training to design and conduct a meta-analysis of his/her own and to competently read and understand the meta-analytic works of others (as well as chapters and papers related to performing this technique). Specifically, the following topics will be covered: what a meta-analysis is (including the goals of meta-analysis and how we should think of successful replication); how to find the literature needed for the analysis (including structuring the search, citation searching, multiple databases, footnote chasing, and browsing); what kind of information should be coded for during the meta-analysis (including prerequisites to full-scale coding and the construction of coding forms); how to calculate effect sizes (including how to combine and compare effect sizes and the difference between random and fixed effects); and the criticisms and defenses of the meta-analytic technique (including sampling bias and the file drawer problem, loss of information, heterogeneity of method and quality, and problems of independence).
