Question

The weights (in pounds) of six dogs are listed below.

17 56 85 38 138 98

The measure of center is found to be 72 lb. Which measure of center is used?

Answer 1

First, we know it can't be median because 72 is not a value in the data. If you find the mean/average, you will find that it is 72
ANSWER: Mean/average

Answer 2

The measure of center is the average or mean.

Explanation:

The weights (in pounds) of six dogs are listed below.

17 56 85 38 138 98

Arranging in ascending order, we get

17 38 56 85 98 138

The measure of center is found to be 72 lb.

This is the average or mean. We can check this as:

`(17+38+56+85+98+138)/(6) =72`
