What is the difference in standard deviation based on n and standard deviation based on n-1? I ask this because I am studying to be a surveyor, and everything we call "standard deviation" is based on n-1, but that's treated as a secondary calculation on all the calculators where "standard deviation" is understood by default to be based on n. The n-based function is easy to find, but the n-1 function has different names and is selected from different places on the calculator. And even though the Ghilani surveying textbook defines n-1 as standard deviation, it's a different result than the standard deviation operation on the calculator menu (based on n). Can you explain why surveyors care about n-1 instead of n?
