1.6

Step-by-step explanation:

The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.

15 is 4 away from 19, for example

So:

19 - 15 = 4

25 - 19 = 6

19 - 13 = 6

19 - 15 = 4

19 - 18 = 1

20 - 19 = 1

22 - 19 = 3

24 - 19 = 5

4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30

30/19 = 1.5789, rounded to 1.6
