Here is a stem and leaf plot. This graph is use for a multiple reasons, one being it condenses the info to just a few numbers. It is a great tool to use when trying to find the median or mode of a given data set. This stem and leaf plot above is grades that came from a science test.  The stem column or the left hand side gives the tens digit while the right column the leaf gives the ones digit and you put them both together and you get a score. Look at the digit 6 in the stem side its paired with a 8, 4, 3 so the scores would be 68, 64, 63 respectively.
