Although statistical power is often considered in the design of primary research studies, it is rarely considered in meta-analysis. Background and guidelines are provided for conducting power analysis in meta-analysis, followed by the presentation of a SAS macro that calculates power using the methods described by Hedges and Pigott (2001, 2004). Several detailed examples are given, including input statements and output. Practical issues in the application of power analysis to meta-analysis are discussed. The macro and examples may be downloaded as supplemental materials for this article from brm.psychonomic-journals.org/content/supplemental.
