Std()

Computes the standard deviation of an array of numbers.

std_dev = Std(array input_values, integer flag)

Argument	Contents
input_values	An array of numbers
flag	0 to compute the population standard deviation; 1 to compute the sample standard deviation

A real number indicating the standard deviation of the values in input_array.

The array must contain numbers only. Other types, including null, are not allowed.

Error Type	Meaning
Error	The array contains values that are null or are not numbers
