Question

Quizplus · Accepted Answer

Standard deviation is a measure of the amount of variation or dispersion of a set of values. By definition, it is always a non-negative value because it is calculated as the square root of the variance, which is the average of the squared differences from the mean. Negative numbers do not affect the positivity of the standard deviation itself.
