Question

Quizplus · Accepted Answer

The standard deviation is calculated by taking the square root of the variations, making it the correct answer. The range is the difference between the largest and smallest values in a dataset, not a measure of dispersion that involves square roots. Variance is the average of the squared differences from the mean, and the arithmetic mean is the average of all values in a dataset. While both of these measures involve square roots in their calculation, they are not the best choice for this question as they are not simply calculated by taking the square root of variations.
