Average of average

[vbourbeau]

Hi,

I want to do something probably easy but I don't figure it out. 

I have a mesure that is an average of value. When I do a table and regroup, the average always remains on all the data but I want to have it on the grouping value. Look bellow, the correct average should be 13.25...

Thank

This looks like a measure aggregation problem. See my blog article about that here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149

There's plenty of solutions as to how to have a measure do a different calcuation dependent on if your measure is working on a total or not which is what you're going to want. Ignoring the fact that the results don't make sense given the data you've presented (the average of 5, 7 and 9 isn't 6.5), the total is calculating the average of all the data, which would be (5+7+9+20)/4, i.e. 10.25

@vbourbeau  use smth like

= calculate(AVERAGEX(Table, AVERAGE('Table'[Value]) ) )

[vbourbeau]

@vbourbeau ,Try like

averagex(Summarize(Table,Table[id],"_1",average(Table[Value])),[_1])
