The list shows the weight in pounds of 6 puppies at birth.

3, 1.6, 2.8, 2.5, 1.7, 2.8

What is the mean absolute deviation of these numbers?

1 answer

To find the mean absolute deviation, you first need to find the mean of the numbers:

(3 + 1.6 + 2.8 + 2.5 + 1.7 + 2.8) / 6 = 2.42

Next, find the absolute deviation of each number from the mean:

|3 - 2.42| = 0.58
|1.6 - 2.42| = 0.82
|2.8 - 2.42| = 0.38
|2.5 - 2.42| = 0.08
|1.7 - 2.42| = 0.72
|2.8 - 2.42| = 0.38

Then, find the average of these absolute deviations:

(0.58 + 0.82 + 0.38 + 0.08 + 0.72 + 0.38) / 6 = 0.48

Therefore, the mean absolute deviation of the weights of the puppies at birth is 0.48 pounds.
