Frequency Polygons. A frequency polygon is another way to show the information in a frequency table. It looks a little bit like a line graph. To make a frequency polygon, you just need to plot a few points and then join the points by straight lines.he reason itâs called a polygon is because the line sort of forms a plane shape with the horizontal axis as one side of the shape: Now a frequency polygon and a histogram both show the same information, but in a different way.
The frequency of a value in a data set is the number of times that that value appears in the set. For example, in the data set {1, 1, 2, 2, 3, 3, 4, 4, 4, 5, 26}, the frequency of the value 3 is two, the frequency of the value 26 is one, and the frequency of the value 6 is zero. frequency bar graph.
