( f ). The frequency designates the number of times the corresponding item occurred in the data set. Relative frequency. of each distinct item is the fraction, or percentage, of the data set represented by the item. If n denotes the total number of items, and a given item, x, occurred f times, then the relative frequency of . x . is. f/n. Example 1
