The standard deviation is derived from variance and tells you, on average, how far each value lies from the mean. It’s the square root of variance. Both measures reflect variability in a distribution, but their units differ:. Standard deviation is expressed in the same units as the original values (e.g., meters).; …

It is used in hypothesis testing via Student's t-test. The t-statistic is used in a t-test to determine whether to support or reject the null hypothesis. It is very similar to the z-score but with the difference that t-statistic is used when the sample size is small or the population standard deviation is unknown. For example, the t-statistic is used in estimatin…
