The interquartile range is used as a measure of variability to overcome the difficulty of the range being influenced too much by extreme values. The interquartile range is calculated by finding the difference between the upper and lower quartiles, which are less likely to be affected by extreme values than the maximum and minimum values that are used to calculate the range.
