Experiment Design Analysis - Studying
Allen wants to see if studying will improve his science grade. Each week he studies a little more and looks to see if his grade goes up for that week. Each week he tries to get enough sleep and doesn't eat strange foods. Work is going OK so he doesn't have that stress in his life.
- 1st week : 0 hours study time = F
- 2nd week : 2 hours study time = C
- 3rd week : 3 hours study time = B
- 4th week : 4 hours study time = B+
