    [Ask] Difference between STDEV() and window_STDEV()

    Randy Adhitama Setiadi

      Hi all,


      I was looking a way to calculate z-score in tableau. Some of the examples are using window_stdev instead of stdev() function. But I didnt get myself clear, whats the difference between using those function?
