Variance Calculator. Given a discrete data set representing a sample or a population, the calculator calculates the mean, variance, and standard deviation and displays the workflow involved in the calculation.
Quick and easy to use var calculator, that also outputs standard deviation, standard error of the mean (SEM), mean, range, and count. Learn what variance is in statistics and probability theory, what is the formula for variance, and practical examples.
Variance calculator is used to find the actual distance of the data values from the mean. This calculator provides the result of the mean, standard deviation, and the sum of squares along with steps.
The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set. The more spread the data, the larger the variance is in relation to the mean.
