Stem and Leaf Plot

Stem and Leaf Plot URL

Stem and Leaf plots are a way to map data graphically.  Information must be shown in chronological order with the stem representing the first set of numbers and the leaf side showing the last number.  For example, in this graph, infant mortality rates in Western Africa are measured showing the amount of infant deaths in each country.  The first row shows 5 on the stem side and 1 on the leaf side; this represents the number 51.  Information is graphed this way in order to see the difference in values and see if there is any outliers present.
