AVERAGE function

Description

Returns the average (arithmetic mean) of the arguments. For example, if the range A1:A20 contains numbers, the formula =AVERAGE(A1:A20) returns the average of those numbers.

Syntax

AVERAGE(number1, [number2], ...)

The AVERAGE function syntax has the following arguments:

• Number1    Required. The first number, cell reference, or range for which you want the average.

• Number2, ...    Optional. Additional numbers, cell references or ranges for which you want the average, up to a maximum of 255.

Remarks

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

• Logical values and text representations of numbers that you type directly into the list of arguments are not counted.

• If a range or cell reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.

• 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 AVERAGEA function.

• If you want to calculate the average of only the values that meet certain criteria, use the AVERAGEIF function or the AVERAGEIFS function.

• 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.
