Returns the sample standard deviation of the values in a data set (this is the square root of the sample variance).
Syntax:
STD(list)
Calculates the sample standard deviation of the values in the list, which may be an array, a range of cells, or a comma-separated list of values.
The equation used is:
√( (n·Σi=n (xi2) − (Σi=n xi)2) ÷ (n·(n − 1)) )
where xi is each value and n is the number of values.
Example:
STD(A1:A15)
returns the standard deviation of the contents of cells in the range A1
to A15
