Tukey introduced several basic exploratory data analytic tools that have since found great popularity and extensive usage. These tools include the stem-and-leaf display, the five-number summary, and a graphical univariate data summary called a box-and-whisker plot, which is now typically called a boxplot. The five-number summary is the basis of a boxplot. It consists of the median, the lower and upper quartiles, and the smallest and largest observation.
