2. Population standard deviation takes into account all of your data points (N). If you want to find the Sample standard deviation, you'll instead type in =STDEV.S( ) here. Sample standard deviation takes into account one less value than the number of data points you have (N-1)
3. As a result, the numbers have a low standard deviation. 3. The numbers below also have a mean (average) of 10. Explanation: the numbers are spread out. As a result, the numbers have a high standard deviation. STDEV.P. The STDEV.P function (the P stands for Population) in Excel calculates the standard deviation based on the entire population

The Standard deviation formula in excel has below-mentioned arguments: number1: (Compulsory or mandatory argument) It is the first element of the sample of a population. [number2]: (Optional argument) It is a number of arguments from 2 to 254 corresponding to a sample of a population. Note: If you have already covered the entire sample data through the range in number1 argument, then no need. Standard Deviation in excel was an inbuilt function in excel for 2007 and older versions which was used to obtain the standard deviation based on a sample given as argument, but in excel versions 2010 and above we have other formulas to calculate standard deviation which is STDEV.P and STDEV.S
