Answer:

The middle 50% of the scores were 20 points apart.

Explanation:

We know that a interquartile range is the difference between the upper quartile (i.e.
Q_3) and lower quartile i.e.
Q_1.

It describes the middle 50% of the value when the data points are ordered from least to highest.

Hence, here the interquartile range is given to be 20 points.

This means that the middle 50% of the scores were 20 points apart.
