Evaluation of Three Sample Size Formulae for 2 X 2 Contingency Tables.
Hornick, Chris W.; Overall, John E.
Journal of Educational Statistics, v5 n4 p351-62 Win 1980
Estimates of sample size requirements for 2 X 2 tables, derived from three approximate formulae, were evaluated by comparison with exact calculations. Although different, the estimates derived from all three formulae were judged adequate for most practical purposes, with the most accurate results being obtained from Cohen's formula. (Author/JKS)
