Use the randomizer.org random number generator to select a proportional stratified sample of APA presidents. Assume that you want a final sample of size 20 APA presidents. As seen in Figure 5.2, 14 of the APA presidents were women (numbered 1–14) and 108 were men (numbered 1–108); about 11.5% of this population is female, and about 88.5% is male. For your sample, 11.5% of 20 rounds to 2 and 88.5% of 20 rounds to 18, so you want 2 female APA presidents and 18 male APA presidents. Therefore, you will want to use the random number generator to select 2 female APA presidents, and use it again to select 18 male APA presidents. Combining the two subsamples, you will have a stratified random sample of APA presidents (with gender as the stratification variable).
