Many times in statistics it is necessary to see if a set of data values is approximately normally distributed. c. class midpoint A pie chart can be used to summarize the data. 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. b. box plot 0.5 Example 1 - Discrete variables; Example 2 - Continuous variables; Other cumulative frequency calculations; Cumulative frequency is used to determine the number of observations that lie above (or below) a particular value in a data set. The sum of the values in the frequency column, 20, represents the total number of students included in the sample. B. class midpoint divided by the class frequency. Similarly, the relative frequency of prices between $3.75 and $3.99 equals 4/20 = 0.20 = 20 percent.

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.
