histogram

A graph in which statistical data is represented by blocks of proportionallysized areas.


stemandleaf plot

A method of presenting numerical data between 1 and 99 by separating each number into its tendigit (stem) and its unitdigit (leaf) and then arranging the data in ascending order of the tendigits.
