Question

multiple choice question
which of the following operations is true regarding relative frequency distributions?

the relative frequency is found by dividing the class frequencies by the total number of observations.
the sum of the relative frequencies is equal to the number of observations.
the sum of the relative frequencies must be less than 1.
no two classes can have the same relative frequency.

Explanation:

• For relative frequency, each class's relative frequency is calculated as the class frequency divided by the total number of observations.
• The sum of all relative frequencies equals 1 (not the number of observations), so the second option is false.
• The sum of relative frequencies is exactly 1, not less than 1, so the third option is false.
• Different classes can have identical relative frequencies if their class frequencies are equal, so the fourth option is false.

Answer:

A. The relative frequency is found by dividing the class frequencies by the total number of observations.
