box-and-whiskers plot

A graph representing data in quartiles, in which the data points above the 25th percentage and below the 75th are included in a box, the data points below the 25th percentage and above the 75th are represented by lines (“whiskers”) below and above the box, and the median is shown by a line within the box. The median is the value that has an equal number of data points above it and below it.
