Create new column which is an average of values in other column

[SJHALANI]

Hi Guys,

I am new to Power Bi and need help with creating a column which should do an average of other 4 columns for every row.
Attaching a screenshot for reference:

So, basically want to create a new column - let's call it Average.

So, Average = average of (0.6686+0.66+0.6616+0.6664)  //taking example of 2nd row

Please help me how can I achieve this using Power query. Thanks!

Hi @SJHALANI , you can add this column Power Query in the "Add column" tab and then "Custom Column" like so:

In the pop-up window you can add the following code:

( [field_16] + [field_17] + [field_18] + [field_19] ) / 4 

Hope this answer solves your problem!

Hi @SJHALANI ,

The answer provided by @goncalogeraldes will work for the most part.

However, I would recommend using List.Average instead as this will correctly handle null values if they occur in your columns:

List.Average( { [field_16], [field_17], [field_18], [field_19] } )
