When you say you get different results, do you mean slightly different results, or wildly different results?

Or to put it another way, is this thread to be a discussion of the details of accumulated rounding errors and limits of precision, or a discussion of what is the correct algorithm to calculate std deviations?

Can you supply a short list of sample data and the output you get with your script and with excel?

Dave.
