The handbook of research synthesis and meta-analysis 2nd edition — Northwestern ScholarsA meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analysis can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. Existing methods for meta-analysis yield a weighted average from the results of the individual studies, and what differs is the manner in which these weights are allocated and also the manner in which the uncertainty is computed around the point estimate thus generated. In addition to providing an estimate of the unknown common truth, meta-analysis has the capacity to contrast results from different studies and identify patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies. A key benefit of this approach is the aggregation of information leading to a higher statistical power and more robust point estimate than is possible from the measure derived from any individual study.

Michael Borenstein, Larry V. Hedges, Julian P. Higgins, Hannah Rothstein Chichester: Wiley. This book provides a very clear overview of meta-analysis — what it is, why we use it, how to perform and interpret a meta-analysis, and how to avoid common mistakes. It starts with basic ideas how to compute an effect size and perform a simple analysis but then moves on to more advanced issues subgroups analysis, meta-regression, multiple outcomes, publication bias. The worked can be accessed here, both as Excel files and as CMA files. This book has been widely adopted as a text for meta-analysis courses, and has consistently been a best-seller on Amazon since its release.
Given the expanding application and importance of literature synthesis, understanding both its strengths and weaknesses is essential for its practitioners and consumers. This volume is a good beginning for those who wish to gain that understanding. This respectability, when combined with the slight hint of mystique that sometimes surrounds meta-analysis, ensures that results of studies that use it are treated with the respect they deserve…. The Handbook of Research Synthesis is one of the most important publications in this subject both as a definitive reference book and a practical manual. Research synthesis is the practice of systematically distilling and integrating data from a variety of sources in order to draw more reliable conclusions about a given question or topic. The Handbook of Research Synthesis and Meta-Analysis draws upon years of groundbreaking advances that have transformed research synthesis from a narrative craft into an important scientific process in its own right.
The Russell Sage Foundation, one of the oldest of Americas general purpose foundations, was established in by Mrs. Margaret Olivia Sage for the improvement of social and living con- ditions in the United States. The Foundation seeks to fulfill this mandate by fostering the devel- opment and dissemination of knowledge about the countrys political, social, and economic prob- lems. While the Foundation endeavors to assure the accuracy and objectivity of each book it publishes, the conclusions and interpretations in Russell Sage Foundation publications are those of the authors and not of the Foundation, its Trustees, or its staff. Publication by Russell Sage, therefore, does not imply Foundation endorsement. Waters, Chair. Kenneth D.

Meta-analysis is an increasingly common method of quantitatively synthesizing research results, with substantial advantages over traditional i. This chapter is an overview of meta-analysis that provides the foundational knowledge necessary to understand the goals of meta-analysis and the process of conducting a meta-analysis, from the initial formulation of research questions through the interpretation of results. The chapter provides insights into the types of research questions that can and cannot be answered through meta-analysis as well as more practical information on the practices of meta-analysis. Finally, the chapter concludes with some advanced topics intended to alert readers to further possibilities available through meta-analysis. Noel A. Deborah M.
