Answer:
3 1/3
Step-by-step explanation:
First find the mean which is (2+6+8+12+12)/5=8 then find the distance from the mean and all the numbers in the data set.
For example 2 is 6 away from 8 and so on
Remember it's called the mean absolute deviation so it has to be the absolute value of the distances.
Distances: 6, 2, 0, 4, 4,
Then do 6+2+0+4+4/5 because even though 0 doesn't add anything, it is still a value in the distances. You get 3 1/3
