Mean: 2+5+6+12+15=40÷5=8

Ignore all minus signs
2-8=6
5-8=3
6-8=2
12-8=4
15-8=7

7+4+2+3+6=22÷5=4.4
The mean absolute deviation is 4.4

The mean absolute deviation of the data set given as, 2, 5, 6, 12, 15 is: 4.4

Recall:

  • The Mean Absolute Deviation (MAD) is given as: the sum of all absolute value gotten from the subtraction of the mean from each data over the number of data set.

Given the data set:

2, 5, 6, 12, 15

The mean = (2 + 5 + 6 + 12 + 15)/5

Mean = 40/5 = 8

The sum of |each data - mean| = 22

  • MAD = 22/8 = 4.4
