How to Calculate variance of proportion?
variance of proportion calculator uses Variance=(Probability of Success*(1-Probability of Success))/(Number of items in population) to calculate the Variance, The variance of proportion formula is defined by the formula
V = sqrt( P * ( 1 - P ) / n ) where,
P is the probability of success
n is the population size. Variance and is denoted by σ^{2} symbol.
