Find the mean absolute deviation of the number of points scored. Round to the nearest hundredth if necessary.

12 25 16 20

31 16 19 22

Mean Absolute deviation = 4.406

Step-by-step explanation:

First start by calculating the mean

Mean = = 20.125

Find the distance of each value from the mean

12 - 20.125 = -8.125

25 - 20.125 = 4.875

16 - 20.125 =  -4.125

20 - 20.125 = -0.125

31 -  20.125 = 10.875

16 - 20.125 = -4.125

19 - 20.125 = -1.125

22 - 20.125 = 1.875

(Exclude the minus signs before adding to get the mean absolute deviation)

Find the mean of the distances

Mean  absolute Deviation =

                                              = 4.40626 to the nearest hundredth
