Find the mean absolute deviation of the data set.
10, 7, 13, 10,8

1st step (find the mean):

Mean: 10 + 7 + 13 + 10 + 8 = 48/5 = 9.6

Mean: 9.6

2nd step ( Subtract the mean ((9.6)) in the following given data set )

9.6 - 10 = 0.4

9.6 - 7 = 2.6

9.6 - 13 = 3.4

9.6 - 10 = 0.4

9.6 - 8 = 1.6

3rd step (Now we have to add up all the difference's ((the numbers that are in bold))

0.4 + 2.6 + 3.4 + 0.4 + 1.6 = 8.4/5 = 1.68

So our final answer would be 1.68 (M.A.D) Mean Absolute Deviation = 1.68

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
