Collaborative Research: Partial and Multilevel Effect Sizes in Meta-analysis

研究人员建议为单水平和多水平回归分析的结果开发和研究部分效应大小指数，并检查这些指数在荟萃分析中的适用性。研究人员提出了一个结合数理统计和模拟研究的工作计划，并用真实的教育例子进行了说明。这项工作将提供研究人员可用于报告复杂的初步研究分析的结果和效果大小的指导方针；促进复杂研究的荟萃分析；并为STEM研究中的初步研究的开展和报告提供信息。

The investigators propose to develop and study partial effect-size indices for results of single and multilevel regression analyses and examine the suitability of the indices for use in meta-analysis. The investigators propose a program of work which combines mathematical statistics and simulation studies, illustrated with real educational examples. This work will provide guidelines that researchers can use in reporting results and effect sizes for complex primary-study analyses; facilitate meta-analyses of complex studies; and inform the conduct and reporting of primary studies in STEM research.
