http://www.shmoop.com/basic-statistics-probability/stem-leaf-plots.html


This is a Stem and Leaf Plot. It is a very clear way to show data. On the left hand side (stem) you have the first digit and that number is what all the numbers on the right (leaf) start with. So the stem with 9, have the numbers 90 and 94. This is a map because it easily shows information over space.
