How to Calculate Variance of Geometric Distribution?
Variance of Geometric Distribution calculator uses Variance of Data = Probability of Failure in Binomial Distribution/(Probability of Success^2) to calculate the Variance of Data, Variance of Geometric Distribution formula is defined as the expectation of the squared deviation of the random variable that follows Geometric distribution, from its mean. Variance of Data is denoted by σ^{2} symbol.
