Power Bi AVERAGE function

The Power Bi AVERAGE function returns the average i.e arithmetic mean of all the numbers in a column.

Whereas the Power Bi returns a decimal number that represents the arithmetic mean of the numbers in a column

The Power Bi AVERAGE function takes a specified column as an argument and finds the average of the values in that column.

Non-numeric values in the column are handled by this function as follows:

  • If the column contains text, no aggregation will be done and the functions returns blank.
  • If the column contains empty cells or logical value, then it returns blank
  • If the columns cells contains 0 are included.

While using the average function you must keep in mind the difference between empty cells and the cells contains 0 values.

The Syntax for Power BI AVERAGE function

Average = AVERAGE(<column>)

Power Bi AVERAGEA function

The Power bi AVERAGEA function returns the average that is the arithmetic mean of the values in a column and also it handles text and non-numeric values.

The Power Bi AVERAGEA function takes a column and averages the number in it, but also handles non-numeric data types according to the following rules:

  • Values that evaluates to true, then the AVERAGEA function count as 1.
  • Values that evaluates to false, then the AVERAGEA function count as 0.
  • Values that contains non-numeric text, then the AVERAGEA function count as 0.

The Power bi AVERAGEX function calculates the average that is the arithmetic mean of a set expression evaluated over a table. Both the table and expression argument is required in this function.

Whereas the table parameter in this function contains the name of a table and the expression parameter contains a scalar result, which will be evaluated for each row of the table. It returns a decimal number.

The AVERAGEX function does not include non-numeric cells or nun cells.

The syntax of the AVERAGEX function in Power BI:

AverageX = AVERAGEX(<table>,<expression>)

AVERAGE Function

We will use the AVERAGE Function, when:

  • We want to find the average of the values in that column.
  • Cells with value as 0 are included.
  • Data type is numeric/integer/Decimal.
  • Does suppoert logical value and text value.

Let’s see the Average function with an example

Average function of number data type

Here we will see how to calculate the average of amount using measure in power bi.

To calculate the average of amount, write the below measure:

AVERAGEA Function:

We will use the Power BI AVERAGEA Function when:

  • The column is boolean type, and Number type.

Here we will see how to find the average of a boolean column using measure in power bi desktop.

To calculate the Average of boolean, write the below measure:

Measure = AVERAGEA('Table'[Boolean ])

As per sample dataset we have 3 true value and 2 false value, So total sum of column values are 3 and number of values are 5. So, it will divide with 3 with 5 and answer will be 0.60.
