Quizplus · Accepted Answer

The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. It does not directly inform about frequency, standard error, or skewness of the distribution.
