I have data from a league over a season. The season was conducted as a round robin so everyone played each other. Each game was a best of 5 so at the least a game produced 3 matches and at the most produced 5. During each match 25 features were collected for each team. There are teams who lost all their matches, teams that won all their matches, and teams that are mixed. What I want to do is find out if there is a statistical difference between a certain feature and how it is correlated with other features in a winning match versus a losing match. I have thought about treating it like two groups (ie male/female) or like pre-post but it doesn't seem to really fit either of those because some teams appear in both groups but not all. Would enjoy any advice!
