Given 180 observations, a data class with an absolute class frequency of 36 must have a relative class frequency of:
A) .10
B) .20
C) .36
D) .18
E) none of these

Question

Quizplus · Accepted Answer

To find the relative class frequency, divide the absolute frequency of the class by the total number of observations:

Relative class frequency = Absolute class frequency / Total number of observations

In this case, the data class has an absolute frequency of 36 out of a total of 180 observations:

Relative class frequency = 36 / 180 = 0.2 or 20%

Therefore, the answer is choice B.
