and we are asked to take a sample of 40 staff, stratified according to the above categories. The first step is to calculate the percentage of each group of the total. % male, full-time = 90 ÷ 180 = 50% % male, part-time = 18 ÷ 180 = 10% % female, full-time = 9 ÷ 180 = 5% % female, part-time = 63 ÷ 180 = 35%; This tells us that of our sample ...
