    This function returns variance based on the entire population, which uses only numeric values.






    Each argument can be a double-precision floating-point value, an integer value, or an array (cell range) of these. Up to 255 arguments may be included. You can use a single array (cell range) instead of a list of values. You can use multiple arrays (cell ranges) as well.


    The variance returns how spread out a set of data is.

    This function uses the following equation to calculate the variance, where n is the number of values.

    VARP Equation

    where x is the value and n is the number of values.

    This function assumes that its arguments are the entire population. If your data represents only a sample of the population, then compute the variance using the VAR function.

    This function differs from VARPA, which accepts logical or text values as well as numeric values.
