A stem and leaf plot is a two-column diagram that organizes a given set of data and shows its frequency distribution. Each data point in a given data set is split into a stem and a leaf. The stem of a data point is all but the right-most digit of that data point, while its leaf is just its right-most digit. Data points with the same stem are grouped together and are individually marked in the stem and leaf plot by listing each of their leafs alongside their corresponding stem.

To make a stem and leaf plot, draw a table with two columns. In the left column, make a list of the distinct stem values which appear in the data set from least to greatest. Then list in the right column the leaves which appear for each stem in increasing order. Repetition of leaf values may occur if a certain data point appears more than once. This means that the number of entries in the given data set determine the number of leaves.

Stem and leaf plots are a convenient way to look at raw data since they allow us to display and analyze data at the same time.

Summarize and describe distributions.
