AVERAGE(number1, number2 [,number3] [,…])

 
 Returns the arithmetic mean for a list of numbers.

 number1The first number.
 number2The second number.
 number3The third optional number.

 REMARKS
 
  		• The arithmetic mean is the total of all the values divided by the number of values.
     
  		• The arguments can be values, cell references, arrays or named ranges.
     
  		• If any arguments evaluate to True, then 1 is used.
     
  		• If any arguments evaluate to False, then 0 is used.
     
  		• If any arguments contain text, then #VALUE! is returned.
     
  		• If any arguments are zero then these are counted.
     
  		• If any cell references contain an error then that error is returned (Row 15).
     
  		• If any cells are empty, then these are not counted, although any cells that contain a zero are counted. Check your (Tools > Options)(View tab, "Zero values").
     
  		• You can enter the abbreviated function name "AVG" although you will be prompted to change this to "AVERAGE".
     
  		• You can have a maximum of 30 arguments.
     
  		• If you do not want to count any arguments that are text or logical values you can use the AVERAGEA() function.
     
  		• AVERAGEIF() - Returns the average of a range of values that match a certain condition.
