The formula will add the Lower Limit and the Upper Limit together and then divide by 2 to find the average, or midpoint. The second cumulative frequency is the sum of the first two frequencies: 20 + 21 =41. Repeat the above process until you have added all the data points. To work out the mean you will need to multiply the midpoint of each group by the frequency, add this column up, and divide the answer by the total frequency. Then we use the polygon () function to create the frequency polygon. Cumulative frequency polygon - Visio Chart List of 200+ Excel shortcuts.
