Let’s choose a cluster for our sample. To do this, choose a random number, r, between 1 and 20. This is the cluster you will use for your sample. Now calculate 5r – 4 , and then 5r. The rectangles with numbers from 5r – 4 to 5r are your cluster. This should be 5 rectangles. Ex: You get the random number 6. 5(6) – 4 = 26 and 5(6) = 30. ................
