Meta-Essentials is a free tool for meta-analysis. It facilitates the integration and synthesis of effect sizes from different studies. The tool consists of a set of workbooks designed for Microsoft Excel that, based on your input, automatically produces all the required statistics, tables, figures, and more. The workbooks can be downloaded from here. We also provide a user manual to guide you in using the tool (PDF / online) and a text on how to interpret the results of meta-analyses (PDF / online).
Meta-Essentials has evolved into a tool that can be used for both research and teaching purposes. Especially for relatively straightforward meta-analyses (excluding for instance meta-regressions and meta-sem), Meta-Essentials is a very easy and intuitive tool to use.
A paper describing the Meta-Essentials tool has been published in Research Synthesis Methods. Besides a general introduction and a more technical comparison to other meta-analysis tools, this paper also includes a short tutorial that you may find useful if you are just starting with meta-analysis in Meta-Essentials.
