The Excel AVERAGE function returns the arithmetic mean of a list of supplied numbers.
Syntax: AVERAGE( number1, [number2], … )
where the number arguments are a set of one or more numeric values, or arrays of numeric values, for which you want to calculate the average – these values can be supplied directly to the function, or as one or more cells or ranges of cells containing numeric values.
In Excel 2007 & Excel 2010, you can provide up to 255 number arguments to the Average function, but in Excel 2003, the function can only accept up to 30 arguments. However, each argument can consist of an array of values or a range of cells, each of which can contain many values.
