Question

Quizplus · Accepted Answer

All the measures of variation are calculated using absolute differences or squared differences, which cannot be negative. The range is calculated as the absolute difference between the maximum and minimum values, while the interquartile range is the absolute difference between the first and third quartiles. The standard deviation and variance are calculated using squared differences, which are always positive. Therefore, all measures of variation can never be negative.
