Correlation between homework and pre-final grades
This isn't particularly shocking, but there is a 87% correlation between your homework average grade and your up-to-the-minute overall grade.
There is not a lot of hidden meaning here: if you did your homework, and did it well, you scored well on everything else by and large. We can say with (much) better than 99.95% confidence that your homework score is a good predictor of your total grade. This establishes correlation but not causation, though in this case I would hazard a guess that doing your homework in fact causes you to do well on everything else.
My current theory is that the final exam scores will follow this plot as well, supposing that it is a bit late to catch up on everything at this point. I am hoping, though, that you prove me wrong!

maybe we shouldn't even have a final then, and just take our homework average as our final grade in the class :)
Believe me, that would make my life a lot easier :-)
Seriously, though, the correlation is only about 85%, it is not perfect. There will be a good 10% of you that move your grade up or down significantly as a result of the final.
I will probably do a post mortem after the final and see how this all worked out - did the homework average accurately predict the final grade and final exam grade, or not.
