Answer 2

22.7

Explanation:

To find the mean absolute deviation (MAD), first find the mean (or average).

μ = (5 + 24 + 38 + 52 + 66 + 85) / 6

μ = 45

Next, subtract the mean from each value and take the absolute value.

|5 − 45| = 40

|24 − 45| = 21

|38 − 45| = 7

|52 − 45| = 7

|66 − 45| = 21

|85 − 45| = 40

Sum the results and divide by the number of animals.

MAD = (40 + 21 + 7 + 7 + 21 + 40) / 6

MAD ≈ 22.7
