[Jprogramming] How to add standard deviation to multiple timings?

I can do this myself with something like tms=. 6!:2 &>100$<'singlePair testSP0' then doing statistics on "tms" but I'm wondering if there's a way to do this more simply. tms=. 6!:2 &>100$<'singlePair testSP0' (mean,stddev) tms 0.260937 0.00313815 Thanks, Devon
