Function Description

The Excel Averagea function returns the arithmetic mean of a list of supplied numbers.

The syntax of the function is:

AVERAGEA( value1, [value2], ... )

where the value arguments are a set of one or more numeric values, or arrays of numeric values for which you want to calculate the average.

Note: In current versions of Excel (Excel 2007 and later), you can provide up to 255 value arguments to the Averagea function, but in Excel 2003, the function can only accept up to 30 arguments. However, each argument can be an array of values or a range of cells, each of which can contain multiple values.

Excel Average vs. Excel Averagea

The Excel Averagea Function is very similar to the Excel Average Function. The only difference between these two functions is the way in which logical values, or text values within arrays or references are treated. This is shown in the table below:

AVERAGE Function AVERAGEA Function
Logical values or text representations of numbers, typed directly into the list of arguments ARE counted
ARE counted
Text that cannot be interpreted as a number, typed directly into the list of arguments #VALUE! error #VALUE! error
Logical values, within arrays or reference arguments Ignored ARE counted
Text (including empty text "", text representations of numbers, or other text), within arrays or reference arguments Ignored Counted as zero
Empty cells Ignored Ignored

Excel Averagea Function Examples

Cells B1-B4 of the following spreadsheet show four examples of the Excel Averagea function, used to calculate the arithmetic mean of the values 8, 1, 9, 6 & 10.

Although the same 5 values are provided to each of the functions, these values are provided to the function in different ways.

  A B
1 8 =AVERAGEA( 8, 1, 9, 6, 10 )
2 1 =AVERAGEA( {8,1,9}, 6, 10 )
3 9 =AVERAGEA( A1, A2, A3, A4, A5 )
4 6 =AVERAGEA( A1:A5 )
5 10  
  A B
1 8 6.8
2 1 6.8
3 9 6.8
4 6 6.8
5 10  

The examples in the above spreadsheets show that each argument to the Averagea function can be supplied as a single number or cell, or as an array of numbers or cells (note that in cell B2, the argument {8,1,9} is an array of numbers).

Averagea Function Errors

If you get an error from the Excel Averagea function, this is likely to be one of the following:

Common Errors
#DIV/0! - Occurs if the arguments to the Averagea function are all references to blank cells.
#VALUE! - Occurs if any of the arguments that are supplied directly to the Averagea function are text values that can not be interpreted as numbers.
