Calculate probability from mean and variance
WebVariance Calculator is a free online tool where you can calculate the variance of a set of numbers. Just enter the data set and select the data type: Sample or Population. Lastly, … WebTo find the variance for a distribution, use the following formula: σ² = ∑x² · p(x) - μ². The variance for a distribution is equal to the sum of each value squared times the probability of the value occurring, minus the mean squared.
