    Issue calculating standard deviation

    Jarrad Murray

      Hi All,


      I am having an issue with calculating a standard deviation from a record level table.


      I have a table with the following aggregated values 243, 309, 452, ,587, ,580, ,447, ,540, ,560, ,518, ,565, ,584, ,613, ,462, ,455. Performing a standard deviation calucation on this gives me a figure of 108.89

      Using the code '=Stdev(aggr(sum({<PODGroup4Description = {'AandE'}>}ActivityActual), MonthYear))' gives me the figure 262.76


      Has anyone encountered this before or does anyone have an idea as to what I am doing wrong.


      Any help is greatly appreciated.
