ments & History Meta Analysis Page

Meta-Stat is a DOS-based computer program that automates the many complex tasks that are required to perform a meta-analysis. With Meta-Stat, you can:

Code the features of each study
Transform study findings into a common metric, called the effect size, so that the studies 
can be compared
Apply statistical techniques to the data
Display the data on a variety of charts

The data can easily be output in ASCII format or in a format ready for use by the Statistical Package for the Social Sciences (SPSS).  Meta-analysis in the traditions of a) Glass, Hedges and Olkin (i.e. effect size), and b) Schmidt and Hunter (i.e. correlational) are supported. Special features include:

An effect-size calculator to help convert from reported metrics to effect-size
Homogeneity statistics
Variance ratio
Fail-safe N
Corrected regression outputs.
Graphical Exploratory Data Analysis

Meta-Stat is free for non-commercial, educational use. We only ask that you reference Meta-Stat in any resultant publications.
