Histogram

http://tstahley.wikispaces.com/Math+Dictionary
Histograms are mainly used to show the distribution of data. Variables are arranged on an x-axis and a y-axis. This example shows the number of employees a business has and the average salary the employees make. You can interpret the graph by saying that the more employees a company has, the less money on average a given employee makes compared to companies of smaller size.
