HOW
1) Arrange the set of numbers in order from least to greatest.
2) Find the median.
3) Find the lower quartile (Q1): the median of all values below the median.
4) Find the upper quartile (Q3): the median of all values above the median.
5) Subtract the lower quartile (Q1) from the upper quartile (Q3).
Examples:
WHY
The interquartile range tells you how spread out the middle 50% of the data is. This measure of variability is not affected by outliers and is often more useful than the range.
