What is stem-and-leaf plot?

A stem-and-leaf plot is a table that is used to display numbers. It is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 21, 2 would be the stem and 1 would be the leaf.

An advantage of the stem-and-leaf plot is that all the data in the data set are shown. A drawback of a stem-and-leaf plot is that it can only be used for a small dataset.

Looking at the stem-and-leaf plot, it can be seen that the professors in their 40s have the highest frequency. They are 14 professors in their 40s.
