I have this rather complicated expression that I would like to express in the most understandable way possible.
The difference of average [something] between the different [something].
I am comparing things by their difference of the average of some metric. I feel that the way I express this is complicated, and I would like to express it in a simpler way.
The problem here is that I can't just say "the average [something] difference between" because it is not the difference that is averaged, and it is important to make that evident.
Is there some other way to more concisely express what I want to say?
