Question 35 • Concepts in Probability and Statistics A
Add the five scores: 100 + 95 + 90 + 98 + 92 = 475. Dividing by 5 gives a mean of 95. In order, the scores are 90, 92, 95, 98, 100, so the middle score—the median—is also 95. Since both measures give the same center and there are no unusually low or high scores, both the mean and the median best represent the data.
