A box-and-whiskers plot is a histogram-like method of displaying data.

A box-and-whisker plot (sometimes called simply a box plot) is a histogram-like method of displaying data, invented by J. Tukey. To create a box-and-whisker plot, draw a box with ends at the quartiles Q_1 and Q_3. Draw the statistical median M as a horizontal line in the box. Now extend the "whiskers" to the farthest points that are not outliers (i.e., that are within 3/2 times the interquartile range of Q_1 and Q_3). Then, for every point more than 3/2 times the interquartile range from the end of a box, draw a dot. If two dots have the same value, draw them side by side. Box-and-whisker plots are implemented in the Wolfram Language as BoxWhiskerChart[data].
