Variance Calculator (High Precision)
About Variance Calculator (High Precision)
The Variance Calculator is used to calculate the variance (population variance and sample variance) of a set of numbers (Step by Step).
FAQ
The sample variance is calculated by following formula:
Where:
s2 = sample variance
x1, ..., xN = the sample data set
x̄ = mean value of the sample data set
N = size of the sample data set
The population variance of a finite population of size N is calculated by following formula:
Where:
σ2 = population variance
x1, ..., xN = the population data set
μ = mean of the population data set
N = size of the population data set
