Two methods of memorizing words are to be compared. You choose two groups of 5 people, where the first person in the first group has the same characteristics as the first person in the second group (they have the same educational level, age, etc.). Same thing about the second person in each group - they are also similar to each other in terms of education, age, etc. Same thing for the third, fourth and fifth people from each group. The first group is assigned to the first method of memorization and the second group to the other method. The number of words recalled in a memory test after a week's training with these two methods is shown below.
Method Pair1 Pair2 Pair3 Pair4 Pair5
Method1 25 30 22 27 29
Method2 21 20 23 18 17
