Abstract and Keywords

Meta-analysis is an increasingly common method of quantitatively synthesizing research results, with substantial advantages over traditional (i.e., qualitative or narrative) methods of literature review. This chapter is an overview of meta-analysis that provides the foundational knowledge necessary to understand the goals of meta-analysis and the process of conducting a meta-analysis, from the initial formulation of research questions through the interpretation of results. The chapter provides insights into the types of research questions that can and cannot be answered through meta-analysis as well as more practical information on the practices of meta-analysis. Finally, the chapter concludes with some advanced topics intended to alert readers to further possibilities available through meta-analysis.

Keywords: Artifacts/Artifact correction, effect size(s), fixed effects, heterogeneity, literature review, meta-analysis, multivariate statistics, research synthesis, random effects
