What kind of effect size measure would you compute based on this? And what would be the corresponding sampling variance?
In this case we would compute z/Sqr(N) where z = binomial z; N = number of trials. Variance = Sqr(1/(1-q)*(1-1/(1-q))/N, where q = chance probability, e.g. .5 Best Patrizio -- Patrizio E.
