RE: Error in Statistics 1Var Report
I misunderstood the purpose of these two functions. I thought that the one with n for the divisor was the (biased) sample estimate and the one with n1 was the (corrected, unbiased) population estimate. (I never saw any documentation stating their interpretation.) Now I understand that the population standard deviation is not an estimate and does not require any correction (simply divide by n).
So, the results in the app are correct and it is actually the case that the functions stddev() and stddevp() are switched?
