Steps to Draw Frequency Polygon. The ability to take counts and visualize them graphically using frequency plots (histograms) enables the analyst to easily recognize patterns and relationships within the data. <> Frequency polygons give an idea about the shape of the data and the trends that a particular data set follows. Instead of bars, the neighbouring points are connected by lines. That is, the relative frequency of a data value is the proportion of the data that have that value.
