Session Abstract (150 words):
Meta-analysis can play a very important role in program evaluation as it provides evaluators with information about the effectiveness of an intervention based on parameters such as context and population subgroups among others. Compared to other systematic review techniques, meta-analysis has the advantage of providing numerical estimates for effect sizes.
This demonstration is divided in two parts. First, we discuss the key concepts in a meta-analysis. Second, we describe the steps needed to conduct a meta-analysis using R. We will present each step with the required R codes followed by an interpretation. The steps will include ways of computing different weighted effect sizes, selecting and understanding the use of fixed or random models, conducting meta-regression, assessing model fit as determined through publication bias. This demonstration is intended as a complement (second part) to the demonstration entitled: “Meta-analysis: The How To for Locating and Coding Studies”
