Commonly used: Standard deviation is a commonly used measure of dispersion. Many analysts are probably more familiar with standard deviation than compared to other statistical calculations of data deviation. For this reason, the standard deviation is used by a variety of professions, from investors to...

We can still estimate the Standard Deviation.But when we use the sample as an estimate of the whole population, the Standard Deviation formula changes to this:The formula for Sample Standard Deviation:The important change is "N-1" instead of "N" (which is called "Bessel's correction").The...

Note.For a sample standard deviation formula to work correctly, the supplied arguments must contain at least two numeric values, otherwise the #DIV/0! error is returned. Functions to calculate population standard deviation in Excel If you are dealing with the entire population, use one of the ...
Standard deviation is the tendency of the data to differ from the mean. Mean, median and mod estimate the midpoint of the data standard deviation tells how much the data is spread out. Standard deviation is the square root of the variance.
