Next, we estimate the sample size required to compare two proportions. To compare two proportions p0 and p1, use the formula: N = 16 p(1 - p) / (p0 - p1)2 where p = (p0 + p1)/2. For example, if p0 = .30 and p1 = .10, then p = .20, so the required sample size per group is 64. As with the comparison of two means, the multiplier of 16 can be changed.
