Controlling Experiment-Wise Type I Error Of Meta-Analysis In The Solomon Four-Group Design, Shlomo S. Sawilowsky

Theoretical and Behavioral Foundations of Education Faculty Publications

Abstract. Stouffer=s Z, a meta-analytic technique, was proposed by W. Braver and Braver (1988) for analyzing data collected from a Solomon Four-group Design. Sawilowsky, Kelley, Blair, and Markman (1994) showed that this technique produces inflated Type I error rates. Recommendations are made to control the false positive inflation of their procedure.
