Returns: Number

The STDDEV function runs the inner function (which itself returns a number) over all elements of the collection, and then returns the standard deviation of the results. Will return 0 if the collection is empty.

Note: If the collection itself is a collection of numbers, you can use the pattern .StdDev(x, @x)
