AVERAGE

AVERAGE

Returns the average (arithmetic mean) of the arguments.
Syntax
AVERAGE(number1,number2,...)
Number1, number2, ...    are 1 to 30 numeric arguments for which you want the average.
Remarks

• The arguments must either be numbers or be names, arrays, or references that contain numbers.


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

Tip

When averaging cells, keep in mind the difference between empty cells and those containing the value zero, especially if you have cleared the Zero values check box on the View tab (Options command, Tools menu). Empty cells are not counted, but zero values are.

SUM

SUM

Adds all the numbers in a range of cells.
Syntax
SUM(number1,number2, ...)
Number1, number2, ...    are 1 to 30 arguments for which you want the total value or sum.
Remarks

• Numbers, logical values, and text representations of numbers that you type directly into the list of arguments are counted. See the first and second examples following.


• 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. See the third example following.


• Arguments that are error values or text that cannot be translated into numbers cause errors.
