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

研究者建议开发和研究单水平和多水平回归分析结果的部分效应大小指标，并检查这些指标在元分析中使用的适用性。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，并以真实的教育实例加以说明。这项工作将提供指导方针，研究人员可以使用在报告结果和效果大小复杂的初步研究分析；促进复杂研究的荟萃分析；并为STEM研究的初步研究的进行和报告提供信息。

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.
