Standard Deviation

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?

Thanks

Try the same formula replacing AVG with STDEV for the standard deviation.  Add/Subtract from the AVG value.
