Question

I don't get it- someone answer this, please.

Answer 1

Use 19, and subtract each number. For example, if it is 15, you do 19 - 15, but if it is over 19, like 24, do 24 - 19. Do this to all the numbers and add them up, thats your mad.

Answer 2

1.6

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
