Standard Deviation

[#1]

Hi

I am working on finding the standard deviation for a list of times from purchased to delivery. I followed the examples in other feeds but I need clarification.

Basically I subtracted the purchased time from the delivered and came up with a new list of time labeled purchasetodeliv.

I created a set analysis for this but unsure if it is correct or not.

Stdev({$< [Status Code]={'Black Shirts'}>}purchasetodeliv)

purchasetodeliv (in hours)

60.5

70.7

19.3

230.1

145

555.6

26.7

Syntax looks right to me... is there anything wrong with the output you get?

Its just that the deviation looks high so I was not sure if I was doing the right thing.

Thanks for the clarification.

Hi Kurleigh,

Formula is correct it stddev should come around 190.20. Refer the below screenshot for reference . It is derived from using your data set values
