Subject:Re: how to calculate an effect size

There is a free shareware program called G power that can be found at

http://www.psycho.uni-duesseldorf.de/aap/projects/gpower/.



Once you install it you can calculate effect size, power and sample

size by plugging in any specifications you would like. I use it in my

classes and it is easy to use.





Best of luck,

Kim Rapoza

I notice some of the

journal articles use very large samples.  Is there a way to

calculate an effect size from a crosstabs table and a logistic

regression table?  Is there a rule on what is considered a big

effect?
