A dot plot has an axis from 0 to 20, but most dots are between 12
and 15. Which statement best describes the center?

The center is about 10 because 10 is the middle of the axis.

The center is about 13 or 14 because that is where the data cluster.

The center is 20 because it is the largest axis value.

The center cannot be described from a dot plot.
