Meta-Analytic Applications in Program Evaluation.
Wolf, Fredric M.
In a variety of psychological and educational situations, it is desirable to be able to make data-based evaluative summary statements regarding the impact of a given program. Certain procedures typically used in meta-analytic studies that review and integrate results from individual studies, such as combined tests and measures of effect size, are particularly well suited for program evaluation in certain situations. This paper describes a number of such situations, briefly reviews the literature on combined tests and effect size, and provides several illustrative numerical examples of their application in program evaluation. The three examples illustrate the practical utility of using combined tests and measures of effect size in program evaluations in situations where data are available either cross-sectionally, or on successive occasions, or on independent components of a larger program. The materials suggest that measures of effect size are clearly valuable in providing potential insight into the differential impact of a given program, information that is more obscured when relying solely on statistical tests.
