BOX AND WHISKERS

A box-and-whisker plot visually indicates five things about a set of data.  It indicates the minimum value, maximum value, median, the range of values, and it segments the data into four quartiles.

Example--box-and -whisker plot of {33, 42, 27, 39, 29, 32, 40, 31}

The box represents the data from the lower quartile to the upper quartile.  The vertical line segment represents the median.  Horizontal line segments called whiskers show the spread of the data to the minimum and to the maximum
