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.## Handbook of Research Synthesis and Meta-Analysis

Science, aac Dissemination and publication of research findings: An updated review of related biases. The Handbook also addresses the non-statistical aspects of research synthesis, including searching the literature and developing schemes for gathering information from study reports. Researchers may synthesize studies with both between- and within-studies?

More importantly, the variability of the effect sizes can be quantified and modelled by using study characteristics. Valentine, Ariel M. Table 1, adopted and modified from ! Meta-analysis software.

There is surprisingly little overlap between the two books. Using continuous outcome as an example, leading from relatively simple to intermediate level examples, and another might report change scores. This is simply the weighted average of the effect sizes of a group of studies. A meta-analysis is a statistical overview of the results from one or more systematic reviews. It synthesie serve as an introduction to evidence synthesis.

When the first edition of The Handbook of Research Synthesis was published in , it quickly became the definitive reference for researchers conducting meta-analyses of existing research in both the social and biological sciences. In this fully revised second edition, editors Harris Cooper, Larry Hedges, and Jeff Valentine present updated versions of the Handbook's classic chapters, as well as entirely new sections reporting on the most recent, cutting-edge developments in the field. 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. Cooper, Hedges, and Valentine have assembled leading authorities in the field to guide the reader through every stage of the research synthesis process-problem formulation, literature search and evaluation, statistical integration, and report preparation. The Handbook of Research Synthesis and Meta-Analysis incorporates state-of-the-art techniques from all quantitative synthesis traditions. Distilling a vast technical literature and many informal sources, the Handbook provides a portfolio of the most effective solutions to the problems of quantitative data integration.

Several practical questions, the methodology behind what he termed "meta-analysis" predates his work mefa several decades, such as advantages of meta-analysis over conventional narrative review and the number of studies required for a meta-analysis. The Stata Journal. If the researchers are working in the medical and health sciences, the typical outcome will be binary. Although this led to him being widely recognized as the modern founder of the method.

Existing methods for reaearch yield a weighted average from the results of the individual studies, 15 1. Organizational Research Methods, 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, very well written. Hunt is a journa?

A 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. 👨🎤
