Meta-Analysis: A Primer

Abstract

In this article, the methods of meta-analysis are discussed. First, problems associated with research integration are outlined: specifically, the limitations inherent with traditional review techniques and the advantages of quantitative methods. The procedures of meta-analysis are then described: specifically, with respect to how they parallel classical scientific method, including problem formulation, sampling, classifying research information, data analysis, and data interpretation. It is concluded that meta-analysis possesses significant advantages for combining and understanding research.
