Question

Quizplus · Accepted Answer

The range is calculated by subtracting the lowest score from the highest score in a distribution, making this the statistic that represents the difference between the highest and lowest scores. Option A is incorrect because average deviation refers to the average of the absolute deviations from the mean, while option B and C are incorrect because they are calculated by squaring the deviations and taking the average, rather than looking at the difference between the highest and lowest scores.
