Question

Quizplus · Accepted Answer

A relative frequency distribution shows the proportion or fraction of the total number of items in each class. It is different from a frequency distribution, which shows the actual number of items in each class. A normal frequency distribution refers to a distribution that follows a normal curve, while a cumulative frequency distribution shows the accumulation of frequencies up to a certain point. Therefore, the best choice for a summary of data showing the fraction of the total number of items in several classes is a relative frequency distribution.
