Variance calculator

Easily calculate the variance of a series of numbers. Enter multiple values ​​and instantly discover how strongly the data deviates from the average with this free variance calculator.

Variance is a statistical measure that indicates how far values ​​deviate from the mean . It is an important measure of the dispersion of data and is widely used in statistics, science , and data analysis.

With this variance calculator , you can quickly and easily calculate the variance of a series of numbers. Enter multiple values, and the tool automatically calculates the variance of the dataset.

What is variance?

Variance indicates how strongly the values ​​in a dataset deviate from the mean . It is an important measure in statistics to determine the spread of data.

The greater the variance, the greater the differences between the values.


Example of variance

Dataset:

2, 4, 6, 8

Average:

5

The variance then calculates how far each number is from this average.


Difference between variance and standard deviation

The standard deviation is the square root of the variance .

Formula:

standard deviation = √variance

Therefore, these two statistical measures are often used together.
