One of the advantages of using a relative frequency distribution is that you can compare data sets that don't necessarily contain an equal number of observations. Construct the frequency table ( including the value / class , frequency , relative frequency and cumulative relative frequency ) for the following data , and graph a pie chart as well as a histogram or bar graph for it . Refer to Exhibit 2-4. The number of students working 19 hours or less d. largest data value/number of classes, 18.

Ensure you enter a zero before the decimal point. In a relative frequency distribution, the value assigned to each class is the proportion of the total data set that belongs in the class. For qualitative data the relative frequency for a class is computed as 1. Because New York has a much larger population, it also has many more gas stations. Other articles where relative frequency interpretation is discussed: probability theory: the interpretation of probabilities as relative frequencies, for which simple games involving coins, cards, dice, and roulette wheels provide examples. This turns out to be 800 in New York and 200 in Connecticut. a. 50.
