STDP

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 = √ ( (ni=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.
