Five-number summary

In descriptive statistics, the five-number summary of a data set consists of:


 * 1) the minimum (smallest observation)
 * 2) the lower quartile or first quartile (which cuts off the lowest 25% of the data)
 * 3) the median (middle value)
 * 4) the upper quartile or third quartile (which cuts off the highest 25% of the data)
 * 5) the maximum (largest observation)

The five-number summary is sometimes represented as in the following table:

The five-number summary can be represented graphically using a boxplot.
