I wish he had discussed the "Lone Wolves" more. There were only three of them, and 2/3 of them were the same score or better. What does that say over the "Mob" answer? How common are outliers like this?
What was his game though? To make the overall class grade better. To prove that a "lone wolf" is worse than the "mob"? The outcome from an educational view seems to be that everyone won. The loner could be a statistical outlier.
