Heterogeneity Estimation in Meta-Analysis: Investigating Methods for Dependent Effect Size Estimates
Peer reviewed Peer reviewed
Direct linkDirect link
Jingru Zhang; James E. Pustejovsky – Society for Research on Educational Effectiveness, 2024
Background/Context: In meta-analysis examining educational intervention, characterizing heterogeneity and exploring the sources of variation in synthesized effects have become increasingly prominent areas of interest. When combining results from a collection of studies, statistical dependency among their effects size estimates will arise when a…

Examining Heterogeneity of Education Intervention Effects Using Quantile Mixed Models: A Re-Analysis of a Cluster-Randomized Controlled Trial of a Fluency-Based Mathematics Intervention
Peer reviewed Peer reviewed

Paul Thompson; Kaydee Owen; Richard P. Hastings – International Journal of Research & Method in Education, 2024
Traditionally, cluster randomized controlled trials are analyzed with the average intervention effect of interest. However, in populations that contain higher degrees of heterogeneity or variation may differ across different values of a covariate, which may not be optimal. Within education and social science contexts, exploring the variation in…
