LOL! esmith and urbanrealtor: you are talking at cross-purposes. esmith says when he can’t get good stats on scholastics, but can get good stats on variables that are correlated with scholastics, he uses the other variables to estimate the scholastics.
urbanrealtor reads that esmith says that if you’re black or hispanic, or your parents are unschooled, then you’ll disrupt your schoolmates’ education. Challenges esmith to withdraw comment or be tattooed as “white male racist bigot” – and a suspected Republican to boot!
One of you needs to teach what correlation means, and the other needs to learn what it means. Good luck!
