- Standard deviation - Wikipedia
The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance (For a finite population, variance is the average of the squared deviations from the mean )

Standard deviation is a measure used in statistics to understand how the data points in a set are spread out from the mean value It indicates the extent of the data's variation and shows how far individual data points deviate from the average

Standard deviation is a statistical measure of variability that indicates the average amount that a set of numbers deviates from their mean The higher the standard deviation, the more spread out the values, while a lower standard deviation indicates that the values tend to be close to the mean
