Question

What is the mean absolute deviation (MAD) of the data set?

{2, 5, 6, 12, 15}

Enter your answer in the box.

Answer 1

2 + 5 + 6 + 12 + 15 = 40
40  ÷ 5 = 8

8-2 = 6
8-5 = 3
8-6= 2
12-8 = 4
15-8 = 7

6 + 3 + 2 + 4 + 7= 22
22 ÷ 5 is 4.4

YOUR ANSWER IS 4.4

Answer 2

And the MAD of the data set is 4.4
