The relative frequency associated with an outcome (such as the tack landing with the point upward, or heads rather than tails in the coin toss, or selection of a yellow candy) will tend toward some number between 0 and 1 (inclusive) as the number of repetitions increases. The long-term relative frequency approaches the probability of the outcome.

The relative frequency of a class is the fraction or proportion of the total number of data items belonging to the class. A relative frequency distribution is a tabular summary of a set of data showing the relative frequency for each class. Percent Frequency Distribution. The percent frequency of a class is the relative frequency multiplied by 100.

The number associated with each category is called the frequency and the collection of frequencies over all categories gives the frequency distribution of that variable. The relative frequency is a number which describes the proportion of observations falling in a given category. Instead of counts, we report relative frequencies or percentages.
