This paper describes the Hunter-Schmidt
method of conducting a Meta-Analysis. Meta-analysis is a set of statistical
procedures designed to accumulate experimental and correlational
results across independent studies
that address a related set of research questions. The paper gives a brief
description of meta-analysis methods based on procedures suggested
by Hunter, Schmidt,and
Jackson (1982), and Hunter and Schmidt (1990). It also presents the formulas
and procedures needed for converting study statistics to a common
metric, calculating
the sample weighted mean effect sizes r and d, and correcting
for range restriction, and sampling and measurement error.
Finally step-by-step details on how to conduct a meta-analysis are presented.
