A stem and leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. As the map above shows, the stem is the first part of the number and the leaf is the second part of the number. Combining these numbers give us the quiz scores that were graded and we see a nice distribution of those numbers here.
