Graeco-Latin Square with NYC SAT Scores

Recall that our Latin Square exercise in this chapter tested the effect of our tutoring program, blocked by Borough and Teacher_Education_Level.

For our Graeco-Latin Square, say we also want to block out the known effect of Homework_Type, which indicates what kind of homework the student was given: individual only, small or large group homework, or some combination. We can add this as another blocking factor to create a Graeco-Latin Square experiment.
