calculate average from aggregated values

HI amitchandak Anonymous 

Thank you for the reply, but I'm not sure, that the results are correct. I have little bit experimented, and found out, that when I use two Summarize function, it will provide correct avg calcualtion. 

Currently, I dont know, how to connect this together, into the first matrix table( I mean the first table in the picture and the third, which shows correct avg values, as the user wants).
