Question

Quizplus · Accepted Answer

The sum of relative frequencies for each interval will always equal 1.00, which represents the entire dataset as a whole. Therefore, option A is the correct answer. Option B is technically equivalent to option A, but it is not as precise. Option C is incorrect because the sum of relative frequencies only represents the proportion of scores in a specific interval, not the total number of scores in the distribution. Option D is redundant because both 1.00 and 100% represent the same proportion, so only one answer choice is necessary.
