Question

The table shows the number of wins of two high school softball teams over the past ten years. Which statement BEST compares the

mean absolute deviation (MAD) of the two sets of data?

Answer 1

D) Westfield's data shows greater variability, since Westfield's MAD is approximately 2.9 times greater than Eastfield's MAD.

Explanation:

Westfield's data shows greater variability, since Westfield's MAD is approximately 2.9 times greater than Eastfield's MAD.

Westfield's MAD = 6.56

Eastfield's MAD = 2.28

Therefore,

6.56

2.28

= 2.877

MAD =

∑|x − X|

n

, where x = Data value, X = Mean, and n = Number of values

Answer 2

the answer is D

Explanation:

D) Westfield's data shows greater variability, since Westfield's MAD is approximately 2.9 times greater than Eastfield's MAD.
