The relative frequency may be expressed as a proportion (fraction) of the total or as a percentage of the total. The number of students who work 19 hours or less is For a relative frequency distribution, relative frequency is computed as _____. Refer to Exhibit 2-3. QUESTIONFor a relative frequency distribution, relative frequency is computed as _____.ANSWERA.) A histogram looks similar to a bar chart but it is for quantitative data. The numbers of branches of the 50 top banks are displayed. A relative frequency is the ratio (fraction or proportion) of the number of times a value of the data . The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors. For example, you calculate the relative frequency of prices between $3.50 and $3.74 as 6/20 to get 0.30 (30 percent). This turns out to be 800 in New York and 200 in Connecticut.
