Three psychologists present the principles of meta-analysis and explain how to conduct one using the SAS programming code. Specifically, this reference illustrates the PROC MEANS procedure in SAS used to perform the computations for the Hunter and Schmidt and Glaussian approaches. The volume expands upon the authors' 1993 article by covering the sample-adjusted-meta-analytic deviancy (SAMD) statistic for detecting outliers, the computation and interpretation of confidence and credibility intervals, and a chi-square test for homogeneity of effect sizes.

Conducting Meta-Analysis Using SAS reviews the meta-analysis statistical procedure and shows the reader how to conduct one using SAS. It presents and illustrates the use of the PROC MEANS procedure in SAS to perform the data computations called for by the two most commonly used meta-analytic procedures, the Hunter & Schmidt and Glassian approaches.

This book serves as both an operational guide and user's manual by describing and explaining the meta-analysis procedures and then presenting the appropriate SAS program code for computing the pertinent statistics. The practical, step-by-step instructions quickly prepare the reader to conduct a meta-analysis. Sample programs available on the Web further aid the reader in understanding the material.

Intended for researchers, students, instructors, and practitioners interested in conducting a meta-analysis, the presentation of both formulas and their associated SAS program code keeps the reader and user in touch with technical aspects of the meta-analysis process. The book is also appropriate for advanced courses in meta-analysis psychology, education, management, and other applied social and health sciences departments.
