A cumulative relative frequency plot may be used to calculate various probabilities. For example, in the plot below, we see that the probability of a battery life of less than 150 is 0.925. If our frequency distribution was developed with inclusive upper bounds, we may obtain cumulative probabilities …

Cumulative Relative Frequency of a class, denoted by F, is the total of the relative frequencies up to that class. To avoid rounding in every class, one may cumulate the frequencies up to a class and then divide by n. The resulting quantity Relative Cumulative Frequency (F/n) is just the same as Cumulative Relative Frequency.
