WebJul 24, 2009 · The value of the standard deviation is then: stdev = sqrt ( (sum_x2 / n) - (mean * mean)) where mean = sum_x / n This is the sample standard deviation; you get the population standard deviation using 'n' instead of 'n - 1' as the divisor. WebThe statistics.variance () method calculates the variance from a sample of data (from a population). A large variance indicates that the data is spread out, - a small variance indicates that the data is clustered closely around the mean. Tip: To calculate the variance of an entire population, look at the statistics.pvariance () method.
