AVERAGEA DAX Function (Aggregation) Not recommended

Returns the average (arithmetic mean) of the values in a column. Handles text and non-numeric values.

Syntax

AVERAGEA ( <ColumnName> )
Parameter Attributes Description
ColumnName

A column that contains the values for which you want the average.

Return values

Scalar A single value of one these types: currency, decimal.

Remarks

The AVERAGEA function takes a column and averages the numbers in it.
Whenever there are no rows to aggregate, the function returns a blank.

AVERAGEA manages a Boolean data type as an integer, where FALSE is 0 and TRUE is 1.
AVERAGEA always consider a string as 0, regardless of the content of the string.

It is useless to use this function in DAX with a string column because the result is always 0, resulting in a different result compared to the corresponding AVERAGEA function in Excel. In order to calculate the average of the numbers included in a column with a string data type, use AVERAGEX instead of AVERAGEA converting the column into a number using VALUE:

Examples

-- The AVERAGEA syntax does not consider the content
-- of a string column (as Excel does)
AVERAGEA ( table[column] )

-- The following AVERAGEX syntax works correctly 
-- when table[column] is a string
AVERAGEX ( 
    table, 
    VALUE ( table[column] ) 
)
