AVERAGEX unexpected behavior.

[Stemar_Aubert]

Hello,

I have an issue with AVERAGEX.

Using it with a simple table created for testing purposes, I get the following and expected results:

Where "at measure" is a simple SUMX(NUMBER 1 * NUMBER 2).

"at avg" is -2.92, which is confirmed by Excel, taking the whole "at measure" column and using the AVERAGEX formula.

Slicing also updates the visual and everything is in order.

However, when run against another measure, I get this:

RepTgtPINSMean is AVERAGEX(Table,Measure), where the Measure is what yields the results of that column.

Should be -0.0196, but it gives another result.

The measure is more complex but of similar domain (-x;+x). They are displayed as % but are decimals numbers.

So it seems that doing AVERAGEX(Table,Measure), I do not get the AVERAGEX of my more complex measure. My intuition is that context is the culprit here. However not so sure about this. 

Thanks for the insights!

Hi @Stemar_Aubert 

If your expected result is the arithmetic mean of all the measure values displayed in the column, you could try @parry2k 's solution. 

Otherwise if your expected result is not that, it's difficult to tell which would be the cause as we don't know how complex the measure is. I think the logic in the expression is also a possible cause besides the context. You could try calculating the numerator and denominator separately to check whether they are calculated correctly to get what you expect.

Kindly let me know if this helps.

@Stemar_Aubert whatever column you are using on the rows (under black color), put that in your measure to get the unique value 

AVERAGEX(VALUES(Table[Column]),Measure)
