Question

What is the mean absolute deviation for the data set?

{10, 15, 18, 20, 24}

3.92

3.95

4.01

4.20

Answer 1

Your answer would be Option A)

Here's a simple step - by - step explanation

10 + 15 + 18 + 20 + 24 = 87

87 ÷ 5 = 17.4

17.4 - 10 = 7.4

17.4 - 15 = 2.4

18 - 17.4 = 0.6

20 - 17.4 = 2.6

24 - 17.4 = 6.6

_________________________

7.4 + 2.4 + 0.6 + 2.6 + 6.6 = 19.6

19.6 ÷ 5 = 3.92

Hence, our answer:

3.92

Answer 2

10 + 15 + 18 + 20 + 24 = 87
87 ÷ 5 = 17.4

17.4 - 10 = 7.4
17.4 - 15 = 2.4
18 - 17.4 = 0.6
20 - 17.4 = 2.6
24 - 17.4 = 6.6

7.4 + 2.4 + 0.6 + 2.6 + 6.6 = 19.6
19.6 ÷ 5 = 3.92

YOUR ANSWER IS 3.92
