Calculates the population standard deviation of the values in a data set.
This is the square root of the population variance.
Syntax:
STDP(list)
Returns the population 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:
STDP = √ ( (n⋅∑i=n (xi2) − (∑i=n xi)2) ÷ n2 )
where n is the number of values and xi is the i-th value.
Example:
STDP(A1:A15)
returns the population standard deviation of cells in the range A1:A15
