How to calculate population variance? Population variance formula We define variance (denoted with the population variance symbol \sigma^2 σ2) as the average squared difference from the mean for all data points. For the population variance, we write it as: \sigma^2 = \frac {\sum (x_i - \mu)^2} {N} σ2 = N ∑(xi − μ)2 where,

The calculator above computes population standard deviation and sample standard deviation, as well as confidence interval approximations. Population Standard Deviation The population standard deviation, the standard definition of σ , is used when an entire population can be measured, and is the square root of the variance of a given data set.

Algorithms for calculating variance - Wikipedia

https://en.wikipedia.org/wiki/Algorithms_for_calculating_variance

Sum ← Sum + x. SumSq ← SumSq + x × x. Var = (SumSq − (Sum × Sum) / n) / (n − 1) This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to ...
