The relative frequency of a data class is the percentage of data elements in that class. For quantitative data, the relative frequency for a class is computed In a frequency distribution, the number of observations in a class is called the class. There are special techniques that can be employed. Exhibit 2-1 673624132684542919338018919147712212214971921221659332430226249314126372417221033251518164222212024.

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.
