Question

Quizplus · Accepted Answer

Real limits for an interval of discrete data are found by subtracting 0.5 from the lower limit and adding 0.5 to the upper limit. Therefore, the real limits for the interval "3-5" are 2.5-5.5. Option B is the only one that includes these values. Option A only lists the interval itself, option C lists an interval that is too narrow, and option D does not provide enough information to calculate the real limits.
