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.
