18. Find the mean absolute deviation, rounded to the nearest hundredth, for the given data set: 20, 22, 32, 20, 20, 45, 52, 60

a. 33.875
b. 16.34
c. 13.875
d. 130.75

Answer 1

C) is right
what you were probably doing wrong was subtracting the mean from the bigger number instead of subtracting the number from the mean. you also have to keep all of the numbers positive in the other mean set.

Answer 2

The Correct Answer is C.
