I press "Stats" and see that sX (sample standard deviation) is 11.2323936 and sigmaX (population standard deviation) is 10.2537256. This answer makes no sense because the bias correction always produces an estimate for the population that is larger than for the sample. Hello, Sample std. dev. has in denominator (n1) but population std. dev has only (n) so after division sample std. dev. will have greater valu, because smaller number in denominator, than population std. dev.
