Calculate variance. Our calculator calculates the variance for you.
Variance (s2) is a measure of the spread in a sequence of numbers. Variance is the square of the standard deviation.
Steps for calculating variance:
1. Find the difference between each number (x) and the mean ((bar{x})).
2. Square (^2) each difference
3. Sum the numbers
4. Divide by the number of values minus 1
To use this calculator, separate each number with a space (e.g., 2 5 4 etc). For decimal numbers, you can use either a comma or a period. Do not use thousand separators or letters.
Formula for variance:
$${\frac{1}{n-1} \sum_{i=1}^N (x_i – \overline{x})^2}$$
