Your analysis is just dumb. You’re implying this is the only difference. You’re implying the entire outcome difference could be due to this one variable. You have shown no evidence to suggest this relationship exists at all. Like, for example looking at other countries. You’re implying that one thing has to account for the entire effect as a linear relationship by saying homicide rate being 2.5x is not important or that they’re “over performing in spite of it”. But you want one? Fine. Cops killed on duty. About 10x in the US. That settles your desire for a linear relationship on a compelling alternative story. Is that actually a sufficient analysis? No.

You get an F for intro to stats. And an F- for being confidently wrong.

There is no “excusing” reductions in education. You have not demonstrated a relationship between these two things as important.
