What is Standard Deviation Calculator?

A Standard Deviation Calculator is a tool used to calculate the standard deviation of a set of numbers. Standard deviation is a measure of how spread out the values in a data set are. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean.

How to Calculate Standard Deviation?

To calculate the standard deviation of a set of numbers, first calculate the mean (average) of the set. Then, for each number in the set, subtract the mean and square the result. Next, add up all of the squared differences. Finally, divide the sum of the squared differences by the number of values in the set, and take the square root of the result. This is the standard deviation.
