Standard Deviation & Variance Calculator

Data Set
Sample Population
Standard Deviation σ = {{result.table.standardDeviationSample}} s = {{result.table.standardDeviationPopulation}}
Variance σ2 = {{result.table.varianceSample}} s2 = {{result.table.variancePopulation}}
Count n = {{result.table.countSample}} n = {{result.table.countPopulation}}
Mean μ = {{result.table.meanSample}} x̄ = {{result.table.meanPopulation}}
Sum of Squares SS = {{result.table.sumSample}} SS = {{result.table.sumPopulation}}

The Standard Deviation & Variance Calculator calculates the mean, variance, and standard deviation of a sample or a population based on the discrete data set you provide, and shows all the intermediate steps of calculations.
