Positive correlation between naming cows between naming cows and milk yield. And milk yield. That's pretty much what we can say here. Now, some people might be tempted to try to draw causality. You'll see this all the time where you see these observational studies and people try to hint that maybe there's a causal relationship here. Maybe the naming is actually what makes the milk yield go up or maybe it's the other way. The cows produce a lot of milk, the farmers like them more and they wanna name them.
