Standard Deviation formula in Result Element

Hello guys,

I have a part with multiple identical cells within it. I am checking simple width and depth of each cell.
The spec asks for a standard deviation of those widths and depths across all cells to be below a certain value.
Is it possible to calculate it using a formula in a Result Element? Can anyone please help with the formula?
basically an equivalent of an excel formula of =STDEV.S(W1,W2,W3,etc).

thanks.

It should be possible to calculate using a formula, however there is no shortcut formula for Standard Deviation in Calypso to my knowledge.

I don't have access to Calypso right now, but you should be able to complete this formula in (several) a Result Elements.

Calculate the mean (the simple average of the numbers) by adding all the data points and dividing them by the
number of data points. Subtract the mean from each data point and square the result. Find the mean of those
squared differences (variance). Find the square root of the variance. This is the standard deviation.

STDEV.P
list(21,36,54,82).sigma

thank you very much!
had to break it into 2 result elements - one for sample mean and one for the sqrt of variance as the overall formula was way too long and messy, but got what i needed.

Thank you!
i have already done it the long way, but good to know there's a shortcut too.
