Originally introduced and popularised by the American mathematician John Wilder Tukey, a Box Plot (also known as a Box and Whisker Plot) is a type of chart ideal for visually communicating the distribution of numerical data through their quartiles and their averages. In contrast to a regular Box-Plot I would like to expand the box to the Minimum and Maximum value of my data instead of the quartiles. When describing a set of data, without listing all of the values, we have seen that we can use measures of location such as the mean and median. A box-and-whisker plot, or box plot, is a tool used to visually display the range, distribution symmetry, and central tendency of a distribution in order to illustrate the variability and the concentration of values within a distribution.
