TLDR
In this article, the authors compared three alternate effect size estimates for repeated measurements in both treatment and control groups, and found that the alternate measures of effect size were less accurate than the original measures.
Abstract
Previous research has recommended several measures of effect size for studies with repeated measurements in both treatment and control groups. Three alternate effect size estimates were compared in...

Challenging the Public Stigma of Mental Illness: A Meta-Analysis of Outcome Studies

TL;DR: A meta-analysis that examined the effects of antistigma approaches that included protest or social activism, education of the public, and contact with persons with mental illness found both education and contact had positive effects on reducing stigma for adults and adolescents with a mental illness.

The effects of integrating mobile devices with teaching and learning on students' learning performance

TL;DR: There was a moderate mean effect size of 0.523 for the application of mobile devices to education and the advantages and disadvantages of mobile learning in different levels of moderator variables were synthesized based on content analyses of individual studies.

Statistical Methods for Meta-Analysis

TL;DR: In this article, the authors present a model for estimating the effect size from a series of experiments using a fixed effect model and a general linear model, and combine these two models to estimate the effect magnitude.

The effects of feedback interventions on performance: A historical review, a meta-analysis, and a preliminary feedback intervention theory.

TL;DR: In this article, KlUGER and Denisi analyzed all the major reasons to reject a paper from the meta-analysis, even though the decision to exclude a paper came at the first identification of a missing inclusion criterion.

Distribution Theory for Glass's Estimator of Effect size and Related Estimators:

TL;DR: In this article, the effect size estimator of Glass's estimator, the sample mean difference divided by the sample standard deviation, is studied in the context of an explicit statistical model.
