Find average of all values in a column (example tables and outputs included)

[water-guy-5]

I'm a little rusty with Power BI so please forgive me.

I have a table with a sales column that looks like this. Let's call it 'Table1'
Location          Sales
A                      500
B                      1000
C                      750
D                      250
E                       1500

I have added a datacard that just calculates the average using the dropdown in the fields pane. Simple enough, right?

When I make a table visual, what I want is a calculate column or measure that shows the average for all locations. So, since the average across all (and the value in my datacard) is 800, I want the output to be this

Location          Sales            Organization Average
A                      500                       800
B                      1000                      800
C                      750                        800
D                      250                       800
E                       1500                       800

That way, I can create a rankx column and rank the locations. I understand that I can just sort the column, but I will be applying this logic to about 5 different areas and want to create a scoring system. I know I have to use ALLSELECTED or ALL but for some reason this is giving me a hard time. Any help would be appreciated, thanks!

Hi,

To be able to rank the locations, you do not need to create a column with those averages.  Try these measures:

Total = sum(Data[Sales])

Rank = rankx(allselected(Data[Locations]),[Total])

Hope this helps.

Hi , @water-guy-5 

According to your description, you want to get the average of the Location.

Here are the steps you can refer to :
[1]If you want to add a calculated column , you can click "New Column" and enter this:

Average Column = AVERAGEX('Table',CALCULATE(SUM('Table'[Sales]) ,ALLEXCEPT('Table','Table'[Location])))

The result is as follows:

[2]If you want to create a measure you can click "New measure" and enter this:

Average = AVERAGEX( ALLSELECTED('Table'[Location]) , CALCULATE(SUM('Table'[Sales])))

The result is as follows:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
