Corruption indicators in Mexico

As you can see there is only a slight positive correlation between the corruption index of the Mexican chapter of Transparency International and the percentage of students who cheated on the Grade 6 ENLACE test*. What I find surprising is that there is a negative correlation between GDP per capita and the percentage of cheaters in ENLACE, but only a slightly negative correlation to the corruption index of Transparency International (except perhaps for the DF). Since test scores increase with income, my best guess is that students who don’t understand the test just start cheating.

As for money being the root of all evil, there’s just not much evidence to support the Willie Sutton theory of Mexican Corruption. Cheating at school tests predicts corruption much better.
