I want to calculate the Standard Deviation for the raw values that make a up the Average

[Dark_Ichigo]

I calculated an Average for a list of values AVG(numbers), I now have a list of those Averaged numbers with the number of transactions.

What I would like to do is calculate the Standard deviation for the raw values that make up the Average, Im confused on How to actually do that with Splunk...

From what I gather, you can do both in the same search.

your_search | stats avg(numbers) stdev(numbers) by trans_id

If you want it over all events, exclude the by trans_id clause.
