Use the Simple Random Sample applet. The Simple Random Sample applet allows you to randomly assign experimental units to more than two groups without difficulty. Example 2.13 (page 46) describes a randomized comparative experiment in which 150 students are randomly assigned to six groups of 25.

(a) Use the applet to randomly choose 25 out of 150 students to form the first group. Which students are in this group?

(b) The "population hopper" now contains the 125 students who were not chosen, in scrambled order. Click "Sample" again to choose 25 of these remaining students to make up the second group. Which students were chosen?

(c) Click "Sample" three more times to choose the third, fourth, and fifth groups. Don't take the time to write down these groups. Check that there are only 25 students remaining in the "population hopper." These subjects get Treatment 6. Which students are they?
