Question 49 • Concepts in Probability and Statistics A
Set 1 has a mean of (30 + 25 + 5 + 32) ÷ 4 = 23, so its absolute deviations average (7 + 2 + 18 + 9) ÷ 4 = 9. Set 2 has a mean of (25 + 30 + 32) ÷ 3 = 29, so its absolute deviations average (4 + 1 + 3) ÷ 3 ≈ 2.7. The difference is 9 − 2.7 = 6.3, so the MAD of set 1 is 6.3 more than the MAD of set 2.
