In statistics the frequency (or absolute frequency) of an event is the number of times the event occurred in an experiment or study.:12-19 These frequencies are often graphically represented in histograms.
Cumulative frequency refers to the total of the absolute frequencies of all events at or below a certain point in an ordered list of events.:17-19
The values of for all events can be plotted to produce a frequency distribution.
Under the frequency interpretation of probability, it is assumed that as the length of a series of trials increases without bound, the fraction of experiments in which a given event occurs will approach a fixed value, known as the limiting relative frequency. This interpretation is often contrasted with Bayesian probability.
