Quizplus · Accepted Answer

The range is the difference between the largest and smallest values in a data set, so D is the correct answer. Standard deviation, variance, and coefficient of variation all measure the amount of spread or variability in a dataset, but they are not specifically the difference between the largest and smallest values. The mean is a measure of central tendency, not variability, so it is not related to the range.
