parents and students really need and should demand is not just the

arrogance of an average - asserting that one number represents

dozens or hundreds or maybe even thousands of individuals, but

rather a distribution of scores by teacher. That means one could look

up a chart of the incoming scores by student for a teacher and see

what outgoing scores a year later have been. After all, if a student

comes in as 578 out of 800, and after a year of work by the student,

parents and teacher, is still a 578 this may not be the best teacher for

this student. Perhaps this teacher is gangbusters for really top

students or is extraordinarily capable with students with dyslexia. But

he or she is probably not the best match for this student.

So more money to hire more teachers or better teachers, right?

Not quite.

If we correlate the county money spent with average county math

SAT we get a rating of -.66821. That's not entirely accurate as

Alpine did not report any scores. If we drop out Alpine's zero we get a

correlation of -0.17178. That means there is barely any statistical

relationship between funding per pupil and achivement.
