One thing that has gone fuzzy for me has been R. Back in stats 314, the proffessor i had didnt put a heavy emphisis on R, and I programed a similar version of it in VBA. Aside from this, the other thing that has gone fuzzy over time has been the formal form of a hypothisis test. The last time I remember writing out a full report with everything was probobly a highschool stats class. That being said, revisiting the topic has been enough to remember the format. In all, today was a great review day.
