Basically, interquartile range represents the width or "dispersion" of the set. [1] The interquartile range is determined by the difference between the top quartile (25% highest) and lower quartile (25% lowest) point of the data set.
From the picture, we can find that:
- The interquartile range of the bus drivers is: 20 -10 = 10
- The interquartile range of the teachers is: 30 -15 = 15
So the interquartile range of the distances for the bus drivers is 5 miles less than the interquartile range of the distances for the teachers.
