Description

Free arithmetic standard deviation calculations online. Find the mean, variance, standard deviation of the given numbers. Can be used for calculating or creating new math problems.

Formula :

Mean: Mean = Sum of X values / N (Number of values)
Standard Deviation: s=sqrt(Σ(X-M)²/(n-1))
Population Standard Deviation: s=sqrt(Σ(X-M)²/n)
Variance: Variance = s²
