STDEVP function

Calculates standard deviation based on the entire population given as arguments. The standard deviation is a measure of how widely values are dispersed from the average value (the mean).

Syntax

STDEVP(number1,number2,...)

Number1,number2,...     are 1 to 30 number arguments corresponding to a population.

Remarks

• Logical values such as TRUE and FALSE and text are ignored. If logical values and text must not be ignored, use the STDEVPA spreadsheet function.

• STDEVP assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the standard deviation using STDEV.

• For large sample sizes, STDEV and STDEVP return approximately equal values.

• The standard deviation is calculated using the "biased" or "n" method.

• STDEVP uses the following formula:
