![]() While the worked example is the analysis of a correlational dataset, the general meta-analytic process described in this paper is applicable for all types of effect sizes. I provide a supplementary R script to demonstrate each analytical step described in the paper, which is readily adaptable for researchers to use for their analyses. The aim of this article is to provide a practical and non-technical guide for psychological scientists that outlines the steps involved in planning and performing a meta-analysis of correlational datasets. Moreover, they are often used to support research grant applications, guide clinical practice, and direct health policy. Outcomes from meta-analyses provide a more objective and transparent summary of a research area than traditional narrative reviews. Meta-analysis synthesizes a body of research investigating a common research question. ![]() NORMENT, KG Jebsen Centre for Psychosis Research, Division of Mental Health and Addiction, Oslo University Hospital, University of Oslo, Oslo, Norway. ![]()
