Meta-analysis is a quantitative technique that uses specific measures (e.g., an effect size) to indicate the strength of variable relationships for the studies included in the analysis. The technique emphasizes results across multiple studies as opposed to results from a single investigation. This article provides an introduction to the meta-analysis literature and discusses the challenges of applying meta-analysis to human dimensions research. Specifically, we review the definitions of meta-analysis techniques, the steps in conducting a meta-analysis, and the advantages and disadvantages of meta-analysis.
