Additional Types of Graphs

• Bar Graph: Very similar to the histogram, it uses bars to represent numerical values. A bar graph does not have to follow a bell shape curve and may only have an upper or lower region. Below represents a typical bar graph.

• Line Graph: Unlike the bar graph, a line graph uses a line to connect dots or points for a given data set; typically to represent changes over time. The below line graph represents changes in river discharge rate over time, which is measured in months.
