I need to calculate the average time between 2 dates and then calculate the average minus 1 standard deviation and then the average plus 1 standard deviation.
This is the expression I am using to calculate the average.
Avg(Aggr(DiscardTimeStamp - SubmittedTimeStamp, serviceRequestID))
This seems to work ok.
Not sure how to calculate the STD and do the above?
Try the same formula replacing AVG with STDEV for the standard deviation. Add/Subtract from the AVG value.
