Answer:

<em>Mean Absolute deviation for (set 1): 4</em>

<em>Mean Absolute deviation for (set 2): 9</em>

Set 2 has a lower (MAD) mean absolute deviation that Set 1.

Step-by-step explanation:

(set 1)

Mean: 80 + 82 + 90 = 252/3 = 84

84 - 80 = 4

84 - 82 = 2

84 - 90 = 6

Mean Absolute Deviation: 2 + 4 + 6 = 12/3 = 4

(set 2)

Mean: 60 + 80 + 82 + 90 = 312/4 = 78

78 - 60 = 18

78 - 80 = 2

78 - 82 = 4

78 - 90 = 12

Mean Absolute Deviation: 2 + 4 + 12 + 18 = 36/4 = 9
