Calculates the sample standard deviation 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 an array, a range of cells, or a comma-separated list of values.
Formula:
STD = √ ( (n⋅∑i=n (xi2) − (∑i=n 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 standard deviation of the contents of cells in the range A1:A15
