Question

What’s measure of center do I use for the graph? And why?

Answer 1

Mean because the data is symmetrical

Step-by-step explanation

The measure of center is the value that describes the center of the data. Two measures of center are mentioned: mean and median.

Depending on the dispersion of the data, we will select one of these measures of center:

• If the data is symmetrical, the best measure of center is the mean.

,

• If the data is skewed, the best measure of center is the median.

In this case, we have a graph that is symmetrical - note that both "crests" have approximately the same height. Hence, the best measure of center to use is the mean.
