KTDRR and Campbell Collaboration Research Evidence Training: An Overview of Meta-Analysis and Effect Size
About the Webcast
The KTDRR Center and the international Campbell Collaboration are working together to offer a five-part training course that focuses on high-quality methods for synthesis of evidence, including the procedures and methods for conducting systematic reviews/research syntheses as well as software, tools, and strategies for analyzing and reporting data. The training materials are developed by representatives of the Campbell Collaboration. Online resources from various national and international organizations will be provided for each session.
This fifth and final webcast in the series is a pre-recorded session that provides an overview of the foundation of meta-analysis: an effect size (a quantitative indicator of a treatment effect or relation between two variables) and discusses the basic processes of a meta-analysis and how the technique can be used to answer complex questions asked by policymakers and practitioners. (NOTE: This session was previously aired live on September 20, 2018.)
