Some Basic Concepts in Meta-Analysis.
Moore, Jenny
The business of science is formulating generalizable insight. No one study, taken singly, establishes the basis for such insight. Meta-analysis, however, can be used to determine if results generalize and to estimate the mean and the variance of effect sizes across studies (J. Hunter and F. Schmidt, 1990). Meta-analysis inquiries treat studies (rather than people) as the units of analysis, and then use regression or other methods to determine the study features that explain or predict variability in detected effects in a given area of inquiry. There are two primary approaches to meta-analysis that are used: the comparison approach and the correlation approach. This paper explains the basic processes of doing a meta-analysis from the mean difference (comparison) approach to determine which of two independent groups or methods scores higher on the variable of interest.
