The response variable, y, is a measure of the strength of the ceramic material (bonded Si nitrate).
You have four factors: lab, table speed [x1]., wheel grit size [x2], and direction [x3].
Determine which of the four primary factors has the strongest effect on the strength of the ceramic material
Estimate the magnitude of the effects
Determine the optimal settings for the primary factors
Eyeball! Histograms, graphs, basic statistics!
T-tests, factorials.
