WebThe cumulative frequency is the total of frequencies, in which the frequency of the first class interval is added to the frequency of the second class interval and then the sum is added to the frequency of the third class interval and so on. WebThe quick way to do it is to multiply each midpoint by each frequency: And then our estimate of the mean time to complete the race is: Estimated Mean = 1288 21 = 61.333... Very close to the exact answer we got earlier. Estimating the Median from Grouped Data Let's look at our data again:
