Meta-Analysis for Explanation brings exemplary illustrations of research synthesis together with expert discussion of the use of meta-analytic techniques. Four meta-analyses prepared by Betsy Jane Becker, Elizabeth C. Devine, Mark W. Lipsey, and William R. Shadish reflect the variety of techniques available to quantitative reviewers. Framing these, chapters written by the authors offer a general overview of the field and a discussion of the scientific value of meta-analysis.
