VAR.P function

Calculates variance based on the entire population (ignores logical values and text in the population).

Syntax

VAR.P(number1,[number2],...)

The VAR.P function syntax has the following arguments:

  • Number1     Required. The first number argument corresponding to a population.

  • Number2, ...     Optional. Number arguments 2 to 254 corresponding to a population.

Remarks

  • VAR.P assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the variance by using VAR.S.

  • Arguments can either be 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 VARPA function.

  • The equation for VAR.P is:

    Equation

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

Example

Formula

Description

Result

=VAR.P(A2:A11)

Variance of breaking strengths for all the tools, assuming that only 10 tools are produced (the entire population is used).

678.84

=VAR.S(A2:A11)

The variance, using the VAR.S function, which assumes only a sample of the population is tested. The result is different from VAR.P.
