Question 554899: A die was rolled eight times. The rolls were 2, 2, 3, 4, 4, 5, 6, and 6. What is the mean absolute deviation for this data? Answer by Edwin McCravy(20060) (Show Source):
The absolute mean deviation is the average difference in absolute
value from the mean
x x-m |x-m|
2 -2 2
2 -2 2
3 -1 1
4 0 0
4 0 0
5 1 1
6 2 2
6 2 2
---- ----
8)32 8)10
m =4 AMD= 1.25
The standard deviation is s = 1.5
