    Standard Deviation Calculation

    NicPickering

      Hi guys,

       

      I'm trying to do some analysis on some tags I have. I want ot find out the standard deviation of the tag values, but want to use the 'sample standard deviation' calculation.

      The SStDev performance equation uses the 'sample' formula, but you have to enter specific values (this is not achievable in my situation)

      The StDev performance equation allows all values within a time frame.

       

      My question is, what formula does the StDev performance equation use? ie. the sample standard deviation formula or the population standard deviation formula.

       

      Cheers
