The manual tells us "s" is calculated, and I think this must be the "estimated" standard deviation based on a sample (not on the population. Can anybody confirm this? ▼ Jeff Kearns Member Posts: 222 Threads: 21 Joined: Oct 2006 05-20-2008, 06:39 PM I can confirm that the 32s standard deviation 's' is a Sample Standard Deviation and not a Population Standard Deviation. The 32sii offers both. -- JK Walter B Posting Freak Posts: 4,587 Threads: 105 Joined: Jul 2005 05-20-2008, 06:41 PM You are definitively right for the 32S. The vast majority of scientific calcs calculate the sample standard deviation, some also the population s.d., none (AFAIK) the standard error (i.e. the s.d. of the mean value). ▼ Thomas Klemm Senior Member Posts: 735 Threads: 34 Joined: May 2007 05-22-2008, 05:29 AM Quote: The vast majority of scientific calcs calculate the sample standard deviation A trick to calculate the population standard deviation would be to calculate the mean and add that value to the data before calculating the sample standard deviation. Just to make sure we're talking about the same things: sample standard deviation: population standard deviation:
