Calculating average values based on filter

[Anonymous]

I want to calculate one total weighted average based on all entries in a table that responds to user selected filters on the table.

In these tables the quantity is the weight and hardiness is the base value. 

So for table 1 the weighted avg would be 4.1785

But for table 2 the overall average would be 3.625

 

How could I show a weighted average for all fields in a filtered table?

Hi @Anonymous ,

Assuming I have your logic right - I think the answer you are expecting is 4.107 when nothing is selected? If so the following should work.

Weighted Avg = 
Var Plantvalue = SUMX(Plants, Plants[Quantity]*Plants[Hardiness ])
Var Quantity = SUM(Plants[Quantity])
Var result = Plantvalue / Quantity
Return
result

Sorry, I'm not super familiar with PowerBI is that a DAX function? Where would I use that?

I think I figured it out. I'm assuming that it would be put into a new measure 🙂
