Experimental Factors
Can’t be changed or assigned, these come as labels on the experimental units
Classification Factors
The original idea that inspires the experiment
Conjecture
Essential component of any experiment that is going tonhave validity
Randomization
The heart of all statictics
Replication
A technique toninclude other factors in our experiment which contribute to undesirable variation
