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. class midpoint divide. Frequencies and Relative Frequencies in Histograms - ThoughtCo Count the tally marks to determine the frequency of each class. To determine the relative frequency for each class we first add the total number of data points: 7 + 9 + 18 + 12 + 4 = 50. In constructing a frequency distribution, as the number of classes are decreased, the class . The relative frequency can be calculated using the formula fi=fn f i = f n , where f is the absolute frequency and n is the sum of all frequencies. 0.14 = 14% students with an F. 0.18 = 18% students with a D. 0.36 = 36% students with a C. 0.24 = 24% students with a B.
