A Measure of Experimental Effect Size Based on Success Rates.
Preece, Peter F.W.
Educational and Psychological Measurement, v43 n3 p763-66 Aut 1983

A new measure of effect size is proposed, which is easily calculated and interpretable in terms of the ratio of success rates in the treatment groups. (Author/BW)
