The relative frequency of a class is computed by:
A) dividing the frequency of the class by the number of classes
B) dividing the frequency of the class by the class width
C) dividing the frequency of the class by the total number of observations in the data set
D) subtracting the lower limit of the class from the upper limit and multiplying the difference by the number of classes
E) adding the lower limit of the class to the upper limit and multiplying the sum by the number of classes

Question

Quizplus · Accepted Answer

The relative frequency of a class is the frequency of that class divided by the total number of observations in the data set. This gives the proportion or percentage of observations that fall into that class. Therefore, C is the correct choice as it divides the frequency of the class by the total number of observations in the data set.
