A stem leaf plot organizes a set of numbers or data to make it easier to read or understand.  The digits in the greatest place value are plotted in the left column (stem) and the digits in the next greatest value is the plotted in the right column know as the leaf. This is an example of a stem and leaf plot demonstrating infant mortality rate in western Africa. The greatest place values are placed in the stem column and the lowest is placed in the leaf column.
