The ages of four groups of 10 workers at a factory are shown, which group has the largest mean absolute deviation?
a) group 1
b) group 2
c) group 3
d) group 4

I think group 1 if it is wrong then write is comment box

group 2

Step-by-step explanation:

The solution is Group 2. To find the mean absolute deviation find the absolute value of the difference between each element and the mean of the data set. Take the average of those differences. The mean absolute deviation for group 2 is 12.7.
