Practical Meta-Analysis Effect Size Calculator
This is a web-based effect-size calculator. It is designed to
facilitate the computation of effect-sizes for meta-analysis.
Four effect-size types can be computed from various input data: the
standardized mean difference, the correlation coefficient, the
odds-ratio, and the risk-ratio.
This calculator is a companion to the 2001 book by Mark W. Lipsey and
David B. Wilson, Practical Meta-analysis, published by Sage.
An older
Excel based version of the calculator can be found at http://mason.gmu.edu/~dwilsonb/ma.html. Additional tools for performing meta-analysis can also be found at that web address.
