Example Of Frequency Polygon. Graph that represents the cumulative frequencies for the classes in a frequency distribution To construct an ogive. From the above figure we can observe that the curve is asymmetric and is right skewed. A frequency polygon is sometimes used to represent the same information as in a histogramA frequency polygon is drawn by using line segments to connect the middle of the top of each bar in the histogramThis means that the frequency polygon connects the coordinates at the centre of each interval and the count in each interval. A frequency polygon is a graphical form of representation of data.
