Returns the population standard deviation of the values in a data set (this is the square root of the population variance).
Syntax:
STDP(list)
Calculates the population 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) ÷ n2 )
where xi is each value and n is the number of values.
Example:
STDP(A1:A15)
returns the population standard deviation of cells in the range A1
to A15
.
