Research on the reproducibility of meta-analyses reveals that errors are common, and the percentage of effect size calculations that cannot be reproduced is much higher than is desirable. Furthermore, the flexibility in inclusion criteria when performing a meta-analysis, combined with the many ...
The practical importance of an effect size depends on the scientific context (i. e., measurement, design, and method) as well as the empirical literature context. Second, researchers need to use all existing data when weighing in on a policy debate; here, meta-analyses are particularly useful...
2.4.2Meta-regression analysis Meta-regression analysis (Hedges and Olkin1985; Lipsey and Wilson2001; Stanley and Jarrell1989) aims to investigate the heterogeneity among observed effect sizes by testing multiple potential moderators simultaneously. In meta-regression, the coded effect size is used as ...
