Std Deviation Calculator. Enter your numbers below the answer is calculated live. A common estimator for σ is the sample standard deviation typically denoted by s.
It is worth noting that there exist many different equations for calculating sample standard deviation since unlike sample mean sample standard deviation does not have any single estimator that is unbiased efficient and has a maximum likelihood. Use our online standard deviation calculator to find the mean variance and arithmetic standard deviation of the given numbers. You use it when you have access to the data of the entire population.
