Standard deviation is a statistical measure of diversity or variability in a data set. It 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. Standard deviation of a data set is the square root of the calculated variance of a set of data.
