The cumulative frequency polygon
WebMar 28, 2024 · To construct a cumulative frequency polygon and an ogive by more than method, we use the following algorithm. Algorithm Step 1 : Start with the lower limits of the class intervals and from the total frequencysubtract the frequency of each class to obtain the cumulative frequency distribution. Web1) Find the class mark for each class interval of the frequency distribution. To make it easier, you can add another column to the frequency distribution to note down the class marks. class mark = u p p e r l i m i t + l o w e r l i m i t 2. 2) Plot the class marks along the horizontal axis and the frequencies along the vertical axis.
