Calculating and Reporting Effect Sizes to Facilitate Cumulative Science: A Practical Primer for t-tests and ANOVAs

Effect sizes can be used to determine the sample size for follow-up studies, or examining effects across studies. This project aims to provide a practical primer on how to calculate and report effect sizes for t-tests and ANOVA’s such that effect sizes can be used in a-priori power analyses and meta-analyses. A supplementary spreadsheet is provided to make it as easy as possible for researchers to incorporate effect size calculations into their workflow.

效应量可用于确定后续研究的样本量，或用于研究间的效应分析。本项目旨在为研究者提供实用性指南，阐述如何计算和报告 t 检验和方差分析（ANOVA）的效应量，以便效应量能够应用于事前功效分析和元分析。同时，提供辅助电子表格，以最大程度简化研究者将效应量计算融入其工作流程的过程。
