The relative frequency for a class is computed as the class

B) midpoint divided by the class frequency.
C) frequency divided by the class interval.
D) frequency divided by the total frequency.

Question

Quizplus · Accepted Answer

Relative frequency is defined as the frequency of a class divided by the total frequency of all classes. This means that only option D, frequency divided by the total frequency, correctly describes the calculation of relative frequency. Option A is incorrect because width and interval are not interchangeable terms. Option B is incorrect because the midpoint is not used in the calculation of relative frequency. Option C is incorrect because frequency is divided by the interval width, which is not the correct formula for relative frequency.
