WorksheetFunction.AverageIfs Method

Office 2007
Returns the average (arithmetic mean) of all cells that meet multiple criteria.

Syntax

expression.AverageIfs(Arg1, Arg2, Arg3, Arg4, Arg5, Arg6, Arg7, Arg8, Arg9, Arg10, Arg11, Arg12, Arg13, Arg14, Arg15, Arg16, Arg17, Arg18, Arg19, Arg20, Arg21, Arg22, Arg23, Arg24, Arg25, Arg26, Arg27, Arg28, Arg29, Arg30)

expression   A variable that represents a WorksheetFunction object.

Parameters

NameRequired/OptionalData TypeDescription
Arg1 - Arg30RequiredRangeOne or more ranges in which to evaluate the associated criteria.

Return Value
Double

Remarks

  • If a cell in average_range is an empty cell, AverageIfs ignores it.
  • If a cell in a criteria range is empty, AverageIfs treats it as a 0 value.
  • Cells in range that contain TRUE evaluate as 1; cells in range that contain FALSE evaluate as 0 (zero).
  • Each cell in average_range is used in the average calculation only if all of the corresponding criteria specified are true for that cell.
  • If cells in average_range are empty or contain text values that cannot be translated into numbers, AverageIfs generates an error.
  • If there are no cells that meet all the criteria, AverageIfs generates an error value.
  • You can use the wildcard characters, question mark (?) and asterisk (*), in criteria. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.
  • Each criteria_range does not have to be the same size and shape as average_range. The actual cells that are averaged are determined by using the top, left cell in that criteria_range as the beginning cell, and then including cells that correspond in size and shape to range. For example:
    If average_range isAnd the criteria_range isThen the actual cells evaluated are
    A1:A5B1:B5B1:B5
    A1:A5B1:B3B1:B5
    A1:B4C1:D4C1:D4
    A1:B4C1:C2C1:D4

The AverageIfs function measures central tendency, which is the location of the center of a group of numbers in a statistical distribution. The three most common measures of central tendency are:
  • Average which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
  • Median which is the middle number of a group of numbers; that is, half the numbers have values that are greater than the median, and half the numbers have values that are less than the median. For example, the median of 2, 3, 3, 5, 7, and 10 is 4.
  • Mode which is the most frequently occurring number in a group of numbers. For example, the mode of 2, 3, 3, 5, 7, and 10 is 3.

For a symmetrical distribution of a group of numbers, these three measures of central tendency are all the same. For a skewed distribution of a group of numbers, they can be different.
