average by filtering doesnt work

Dear Community,

 

I dont understand why the average doesnt work when I use  filter: For example: if I choose a sell team I get the right percentage of sells but if I choose 2 sells team I dont get the right avarege between those two.

 

Any Advice?????

 

In the first picture The 76.62% should be 79,44% considering those two sells team (101-104)

Re: average by filtering doesnt work

It’s most likely due to the way Power BI filters first, then calculates. Eg

 

team A has 3 records

5,6,7 = avg of 6

 

team B has 6 records

10,12,10,20,18,20 = avg 15

 

avg across both teams = 10.5

 

but Power BI will add the total (108) divided by 9 = 12

 

you can solve it with averagex

 

=AVERAGEX(values(table[team]),[your measure]]
