Sad Sad IfA

IfA full professor salaries for 2001-2002 and average credits taught for that year show a negative correlation between salary and amount of teaching. A simple fit shows that if you teach over 4 credits, you make $0 and you gain $26,000 in salary for every credit you don't teach. Lots of scatter too. Maybe that says teaching is irrelevant to professorships. Either satement isn't great. I wonder why people say we're slipping....
