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.
