Calculates the sample standard deviation[1] of the values in a data set.
This is the square root of the sample variance.
Syntax:
STD( list )
Returns the sample standard deviation of the values in the list.
list may be a range of cells, an array, or a comma-separated list of values (which may contain cell references and also ranges of cells as one or more of its elements).
Formula:
STD, s = √ ( ( n⋅i ∑1n (xi2) − (i ∑1n xi)2 ) ∕ (n⋅(n − 1)) )
where n is the number of values and xi is the i‑th value.
Example:
STD(A1:A15)
returns the sample standard deviation of the contents of cells in the range A1:A15
