Power BI: calculate the average of unique values
I have this table:
If I do an average, I got 95.76%, the point is that this calculation includes the duplicate numbers and what I want, it is to have an average of unique percentage to get 93.55%.
This is the formula:
AVERAGEX(DISTINCT(SELECTCOLUMNS(FILTER('table','table'[argument1]='table'[argument1]),"new name",[argument2])),[new name])
If I have other months and I want it per month, I will add another condition in the formula:
AVERAGEX(DISTINCT(SELECTCOLUMNS(FILTER('table','table'[argument1]='table'[argument1]),"new name1",[argument2],"new name2",[argument3])),[new name])
Based on my table, this formula may not work so alternatively, I use this one:
AVERAGEX(SUMMARIZE('table','table'[argument1],'table'[argument2]),'table'[argument2])
