Stem and Leaf plots help to organize and visualize a set of numbers to be easily used to calculate with. The stem of the plot represents the tens numbers of the data set and the leaf of the plot represents the ones of the data set. The one above is almost a short hand of writing the numbers down. For example, the 5 in the last row on the left can be put together with the zero on the right side of it making it 50, so there are two 50s.
