Replaces the contents of the result variable with the sample standard deviation of the input vector. If the keyword As an alternate to Missing values, represented by "NaN" or ".", are ignored in the computation of the standard deviation.
You can use STDEV as a function in the LET command. By default, it will compute the sample standard deviation. If you want to use it to compute population standard deviation, use the name STDEV_POP, which is only valid within a LET command. |
