STDEV.P is a function in Google Sheets that calculates the standard deviation of a population. To use it, you first need to enter the data set that you want to calculate the standard deviation for. Then, in the cell where you want the calculation to appear, type in "STDEV.P(" and then highlight the data set. Press enter, and the standard deviation will appear in the cell.
The syntax of STDEV.P in Google Sheets is as follows: =STDEV.P(number_1, number_2, ...)
The example below calculates the standard deviation of a set of numbers using the STDEV.P function in Google Sheets. The function takes a range of numbers as its input and calculates the standard deviation of those numbers. In the example, the standard deviation is calculated for a set of test scores.
There are a few instances in which you should not use STDEV.P in Google Sheets. One instance is when you have a list of numbers that are not in numerical order. In this case, the STDEV.P function will not work correctly. Another instance in which you should not use the STDEV.P function is when you have a list of numbers that includes zero values. In this case, the STDEV.P function will give you the incorrect standard deviation.
There are a few similar formulae to STDEV.P in Google Sheets. One is STDEV.S, which calculates the standard deviation of a sample. Another is VAR.P, which calculates the variance of a population. Finally, there is VAR.S, which calculates the variance of a sample.
