What is the MAD for this data set. 79,82,84,81,77,85,82,80,78,83 Also, tell me how you did it by giving all the work you done to solve it.
+129839 1. Find the mean (average)
[79+ 82 + 84 + 81 + 77+ 85+ 82+ 80+ 78+ 83 ] / 10 = 81.1
2. Find the difference between each data value and the mean and take the absolute value of each difference
abs [79 - 81.1] = 2.1
abs [82 - 81.1] = .9
abs [84 - 81.1] = 2.9
abs [81 - 81.1] = .1
abs [77 - 81.1] = 4.1
abs [82 - 81.1] = .9
abs [85 - 81.1] = 3.9
abs [80 - 81.1] = 1.1
abs [78 - 81.1] = 3.1
abs [83 - 81.1] = 1.9
4. Find the mean (average) of these differences
[ 2.1 + .9 + 2.9 + .1 + 4.1 + .9 + 3.9 + 1.1 + 3.1 + 1.9 ] / 10 = 2.1 = MAD
