I have a players, who have played in multiple games and each player is ranked local. For example:
Player1 = {1,2,2,1,2,3,1} Player2 = {2,1,3}
Now I want to create a global ranking from the locals. What is the best approach to do that? I tried it with t-Test, but having Players like this:
Player1 = {1,1,1,1,1,1} Player2 = {2,2,2,2,2,2}
I receive a p value, which is NaN
Edit: The players don't have the same amount of played games.
Thanks in advance!
