In statistics, relative frequency refers to the number of times a specific event occurs within the total number of observations. It is a type of frequency that is often expressed as a percentage, proportion, or fraction. The formula for relative frequency is given by (\dfrac {f}{n}), where (f) is the frequency of the event and (n) is the total number of observations
. Unlike probability, which is a measure of an expected event, relative frequency measures an actual event that has already occurred
