What characteristics allow plants to survive in the desert? The main advantage of cumulative percentage over cumulative frequency as a measure of frequency distribution is that it provides an easier way to compare different sets of data. -very informative when examining how values are changing within Cumulative frequency; 5. 14. But to interpret the rate of change you need to look past steep lines to decipher subtler changes by time period.
