Introduction to Meta-Analysis

Meta-analysis is a statistical procedure for combining the results from multiple studies in an effort to increase power (over individual studies), improve estimates of effect sizes, or to resolve uncertainty when research disagrees. In this workshop, we will provide an introduction to the theory and statistical methods behind meta-analysis. Topics will include:

  • Extraction of data from studies
  • Converting among effect sizes
  • Effect sizes
  • Fixed effects versus random effects models
  • Heterogeneity
  • Visualization and presentation of results
