心理科学的统计实践正在经历改革，这在一定程度上反映在对报告和解释效应大小及其置信区间的强烈建议上。我们提出研究报告的原则和建议，并强调报告效应大小的多种方式。此外，我们强调解释和报告非标准化效应大小，因为我们对标准化效应大小存在常见的误解。效应大小应直接回答其激励性研究问题，为普通读者所理解，并基于其组成变量的有意义的指标。我们用涉及单向方差分析、分类变量分析、线性回归中的交互效应和简单中介模型的实证示例来说明我们的建议，强调效应大小的解释。
Statistical practice in psychological science is undergoing reform which is reflected in part by strong recommendations for reporting and interpreting effect sizes and their confidence intervals. We present principles and recommendations for research reporting and emphasize the variety of ways effect sizes can be reported. Additionally, we emphasize interpreting and reporting unstandardized effect sizes because of common misconceptions regarding standardized effect sizes which we elucidate. Effect sizes should directly answer their motivating research questions, be comprehensible to the average reader, and be based on meaningful metrics of their constituent variables. We illustrate our recommendations with empirical examples involving a One-way ANOVA, a categorical variable analysis, an interaction effect in linear regression, and a simple mediation model, emphasizing the interpretation of effect sizes.
