Frequency Polygons are graphs that are constructed out of a frequency table. To create a Frequency Polygon just follow these steps: 1) Create a histogram. 2) Plot the midpoints for each bar on the histogram. 3) Plot a point with a value of zero one bar below the smallest class. Also plot a point with a value of zero one bar above the largest class.
