Calculate the standard deviation, variance, and mean of a data set.

What is Standard Deviation?

Standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range.

How to Use

Enter your data set separated by commas or spaces. The calculator will automatically compute the mean, variance, and sample standard deviation.
