Question

What is the MAD of the data set?

{13, 6, 3, 7, 11}

Answer 1

MAD = 3.2

Explanation:

13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5

6 - 8 = |-2| = 2

3 - 8 = |-5| = 5

7 - 8 = |-1| = 1

11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2

Answer 2

13 + 6 + 3 + 7 + 11 = 40

40 ÷ 5 = 8

13 - 8 = 5
6 - 8 = |-2| = 2
3 - 8 = |-5| = 5
7 - 8 = |-1| = 1
11 - 8 = 3

5, 2, 5, 1, 3

5 + 2 + 5 + 1 + 3 = 16

16 ÷ 5 = 3.2

MAD = 3.2
