When a class interval is expressed as 100 up to 200, Observations with values of 200 are excluded from the class, For a relative frequency distribution, relative frequency is computed as. For example, suppose that a researcher is interested in comparing the distribution of gas prices in New York and Connecticut. For qualitative data the relative frequency for a class is computed as class A. Luppi's c. 70 In a relative frequency distribution, the value assigned to each class is the proportion of the total data set that belongs in the class. In a frequency distribution, the number of observations in a class is called the class. Based on this information, you can use the relative frequency formula to create the next table, which shows the relative frequency of the prices in each class, as both a fraction and a percentage.
