Remarks

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

  • 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 VARA function.

  • VAR uses the following formula:

    Formula

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