Answer:
2.33.
Step-by-step explanation:
First we find the mean by adding the values and dividing by 11 (the number of values).
mean = 62 / 11
= 5.636
Now, we list the absolute differences between each value and the mean:
9 - 5.636 = 3.364 the others are:
3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636
Now the MAD is the sum of these values / 11.
MAD = 25.636/11
= 2.33..
