In statistics, the frequency or absolute frequency of an event is the number of times the observation has occurred or been recorded in an experiment or study. The relative frequency is the ratio of absolute frequency to the sample size. The cumulative frequency is the total of the absolute frequencies of all events at or below a certain point in an ordered list of events. These frequencies are often depicted graphically or in tabular form. They may be used as estimators of empirical probabilities or cumulative distribution functions, for instance.
