Webπ = π 2 is the proportion in the reference group. r = n 1 / n 2 (ratio of sample sizes in each group) p o = the common proportion over the two groups. When r = 1 (equal-sized groups), the formula above reduces to: p c = π ( λ + 1) 2 = π 1 + π 2 2. For our example, n=448 - that is 224 in each group. The table below can also be used to ...
