Reading Distributions

Use each display to describe the distribution.

$Dot plot of test scores from 65 to 95. Dots stack highest at 80 with 4 dots. The distribution is roughly symmetric around 80.$

Use the dot plot of test scores below (values from 65 to 95). Which statement correctly describes the spread?

The spread is from 65 to 95, a range of 30 points, with most scores between 75 and 90.

The spread is just 65 to 95.

The spread is 80 because that is the center.

The spread cannot be determined from a dot plot.
