The population standard deviation, the standard definition of σ, is used when an entire population can be measured, and is the square root of the variance of a given data set. The calculator above computes population standardĭeviation and sample standard deviation, as well as approximations. When used in this manner, standard deviation is often called the standard error of the mean, or standard error of the estimate with regard to a mean. In addition to expressing population variability, the standard deviation is also often used to measure statistical results Similarly to other mathematical and statistical concepts, thereĪre many different situations in which standard deviation can be used, and thus many different equations. Conversely, a higher standard deviation indicates a wider range of values. The lower the standardĭeviation, the closer the data points tend to be to the mean (or expected value), μ.
