The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
Cumulative frequency is the running total of frequencies. It can be shown on a graph by joining points. For example if frequencies are 4, 6, 3, 2, 6, 10 then their cumulative frequencies are 4, 10, 13, 15, 21 and 31 respectively.
