The relative frequency of a class is computed by
A) dividing the cumulative frequency of the class by the total number of elements in the data set.
B) dividing n by cumulative frequency of the class.
C) dividing the frequency of the class by the total number of elements in the data set.
D) dividing the frequency of the class by the number of classes.

Question

Quizplus · Accepted Answer

The relative frequency of a class is calculated by dividing the frequency of the class by the total number of elements in the data set. This gives the proportion or percentage of the total data that falls in the class. Option A is incorrect since it divides the cumulative frequency by the total number of elements, which would lead to an incorrect proportion. Option B is incorrect because it divides n, which is the total number of elements, by the cumulative frequency, which would not result in a proportion. Option D is incorrect because it divides the frequency of the class by the number of classes, which is not relevant to finding the relative frequency of a class.
