michael ... there MAY BE one but ... there would also have to be some notion of a standard error OF an effect size or, in your case ... some standard error of the difference in effect sizes ... would there not? let's say that we run two independent experiments where in EACH experiment ... say with an E versus a C group ... you get an effect size statistic ... this leads to a difference in effect sizes ... THAT would be your sample statistic ... and, what would this distribution of differences in effect sizes look like? without some formula for an estimate of the SD of that sampling distribution ... not sure it would be doable ... but, then again, maybe there already is a solution to this matter >******************************************************************* >Michael M.
