• Example: Suppose we want to know whether or not three different exam prep programs lead to different mean scores on a certain exam. To test this, we ask 30 students to participate in a study and split them into three groups. The students in each group are randomly assigned to use one of the three exam prep programs for the next three weeks to prepare for an exam. At the end of the three weeks, all of the students take the same exam. Assuming that the three groups are coming from a normal distribution with the same variance. The exam scores for each group are shown in the following table:
