Abstract
This article discusses the meta-analysis of raw mean differences. It presents a rationale for cumulating psychological effects in a raw metric and compares raw mean differences to standardized mean differences. Some limitations of standardization are noted, and statistical techniques for raw meta-analysis are described. These include a graphical device for decomposing effect sizes. Several illustrative data sets are analyzed.
摘要
本文讨论了原始均值差异的元分析。它提出了在原始指标中累积心理效应的基本原理，并将原始均值差异与标准化均值差异进行了比较。指出了标准化的一些局限性，并描述了原始元分析的统计技术。这些技术包括一种用于分解效应大小的图形工具。分析了几个说明性数据集。
