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 :

Answer:

g)6.88

Step-by-step 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
I think it is H as well
