This free standard deviation calculator computes the standard deviation, variance, mean, sum, and error margin of a given data set.

November 4, 2025 - Calculates variance and standard deviation for a data set. Calculator finds variance, the measure of data dispersion, and shows the work for the calculation.

Are you interested in measuring the dispersion of your data? Then select one or more metric variables and decide on the variance, standard deviation, range or minimum and maximum of the distribution.

The Standard Deviation is a measure of how spread out numbers are. ... The formula is easy: it is the square root of the Variance. So now you ask, "What is the Variance?" ... The average of the squared differences from the Mean.

June 21, 2023 - Since a square root isn’t a linear operation, like addition or subtraction, the unbiasedness of the sample variance formula doesn’t carry over the sample standard deviation formula. You can calculate the variance by hand or with the help of our variance calculator below.

November 10, 2025 - To calculate the variance and standard deviation of the above dataset in R, we can create a variable for the data and then calculate the variance and standard deviation with the var and sd functions respectively:
