Query: Straight forward Meta-Analysis

I found this book very clear and practical. Even for students not interested in doing their own meta-analysis, understanding the basics:1) Makes it easier to include the statistics needed for others to include your research in a meta-analysis2) Aides in understanding meta-analytic review papers3) Emphasizes the importance of replication---no single study no matter how well designed or how statistically "significant" the results, should be regarded as conclusive until it has been replicated.Dr. Rosenthal is a researcher in psychology, but there are also examples from other fields and I think that social scientists in general and basic medical researchers would find this useful.
