Compatibility - STDEVP Function

The STDEVP function replaces the STDEV.P function in Excel 2010.

Description

The function calculates the 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],...)

Arguments

Argument Description Required/ Optional
Number1 The first number argument corresponding to a population. Required
Number2, ...

Number arguments 2 to 255 corresponding to a population.

You can also use a single array or a reference to an array instead of arguments separated by commas.

 Optional

Notes

  • 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 "n" method.

  • Arguments can be either numbers or names, arrays, or references that contain numbers.

  • Logical values and text representations of numbers that you type directly into the list of arguments are counted.

  • If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.

  • Arguments that are error values or text that cannot be translated into numbers cause errors.

  • If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVPA function.

  • STDEVP uses the following formula −

    $$\sqrt{\frac{\sum(x-\bar{x})^2}{n}}$$

    Where x is the sample mean AVERAGE (number1,number2,…) and n is the sample size.
