Cumulative frequency table
Work Step by Step
To make a cumulative frequency table you need to know the number of observation that lies above a data set value. In this dataset, the frequency of 1-3 miles is 13 so the cumu. freq would be 13 because it is the only frequency that happened. The frequency of 4-6 would be 5 and the cumu. freq would be 18 because you add the previous cumu. freq and the new frequency together. In 7-9 miles the frequency would be 2 and the cumu. freq would be 20. In 10-12 miles, the frequency would be 2 and the cumu.freq would be 22.
