 Histogram:  A way of displaying numeric data using horizontal or vertical bars so that the height or the length of the bars indicates the frequency.

The graph below displays average teacher salaries from 1985. It is a histogram because each bar represents the number of states that pay their teachers a specified average salary. For example, in 1985, approximately 5 states paid their teachers an average salary of $18,000 a year.
