Example mean = \frac{2 + 4 + 6 + 8}{4} = 5 MAD = \frac{3 + 1 + 1 + 3}{4} = 2 Think: For 2, 4, 6, 8: each value is 3, 1, 1, and 3 away from the mean of 5. The MAD is the mean of those distances. 1 20, 2, 3, 14, 6 Mean MAD 2 2, 19, 20, 19, 15 Mean MAD 3 12, 10, 18, 15, 10 Mean MAD 4 2, 15, 2, 15, 11 Mean MAD 5 3, 6, 10, 10, 16 Mean MAD 6 1, 6, 19, 4, 5 Mean MAD 7 8, 1, 6, 10, 10 Mean MAD 8 1, 6, 7, 8, 13 Mean MAD Daniel Math Academy \cdot danielmath.com Worksheet # qphrh9i \cdot Page 1 / 2 Daniel Math Academy \cdot Grade 7 Math Answer Key N.3 Mean Absolute Deviation \cdot ★★☆ Medium 1 Mean 9 \cdot MAD 6.4 2 Mean 15 \cdot MAD 5.2 3 Mean 13 \cdot MAD 2.8 4 Mean 9 \cdot MAD 5.6 5 Mean 9 \cdot MAD 3.6 6 Mean 7 \cdot MAD 4.8 7 Mean 7 \cdot MAD 2.8 8 Mean 7 \cdot MAD 2.8 Daniel Math Academy \cdot danielmath.com Worksheet # qphrh9i \cdot Answer Key \cdot Page 2 / 2
