Calculates variance and standard deviation for a data set. Calculator finds variance, the measure of data dispersion, and shows the work for the calculation.
Free Variance Calculator - find the Variance of a data set step-by-step
Steps to calculate the variance. The following steps are involved in the calculation of variance. Step 1: Calculate the sample/population mean. This is the sum of all data points divided by the number of data points (n for a sample and N for the population), i.e., Sample mean: $$\bar{x}=\frac{\sum_{i=1}^{n} x_i}{n}$$

Variance Calculator finds the variance, standard deviation, mean, and sum of squares of comma separated values with steps
Use the variance calculator to compute both sample variance and population variance, complete with a step-by-step solution, and then present the results in APA format. What is Variance? Variance is a parameter that measures the variability of data.
There are five main steps for finding the variance by hand. We’ll use a small data set of 6 scores to walk through the steps. To find the mean, add up all the scores, then divide them by the number of scores. Subtract the mean from each score to get the deviations from the mean. Since x̅ = 50, take away 50 from each score.
