A boxplot summarizes the information contained in a data set by displaying 5 characteristics of the set. It is defined by a box of length x0.75 - x0.25 (interquartile range, defining the "inner 50%" of the data ordered by increasing size), the median x0.5 (marked inside the box) and the extreme values xmin and xmax. The latter are connected with the box via lines. The total length of a boxplot represents the range of the data set.
