Frequency (statistics)

Number of occurrences in an experiment or study

In statistics, the frequency or absolute frequency of an event i {\displaystyle i} is the number n i {\displaystyle n_{i}} 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.
