Detailed Solution & Explanation
The relative frequency of a class is defined as the ratio of the frequency of that class () to the total frequency ( or ) of the distribution:
Since frequency is a count of occurrences, it is always a non-negative number:
Additionally, the frequency of any single class cannot exceed the total frequency of all classes:
Thus, the relative frequency of any class must satisfy the inequality:
This means that the relative frequency lies between and , **both inclusive** (it can be if the class contains no observations, or if all observations fall into that single class). This corresponds to Option B.
Hence, **Option B** is the correct answer.
