Question

The list shows the number of songs that five students each downloaded last week.

32, 43, 38, 28, 51
What is the mean absolute deviation of the numbers in the list?
F 34.4
G 6.88
H 38.4
J 7.68

Answer 1

I think it is H as well

Answer 2

g)6.88

Explanation:

We’ll begin by finding the mean of the data set.

32+43+38+28+51=192 then 192/5=38.4

Then find the absolute value of the difference between each data value and the mean.

l32-38.4l=6.4

l43-38.4l=4.6

l38-38.4l=0.4

l28-38.4l=10.4

l51-38.4l=12.6

Lastly, find the sum of the absolute values and divide by the number of the values

6.4+4.6+0.4+10.4+12.6=34.4

34.4/5=6.88
