DESIGN OF EXPERIMENT
FULL FACTORIAL DESIGN Stop angle has the largest impact on the distance traveled by the projectile while arm length and start angle are relatively similar in terms of significance. FRACTIONAL FACTORIAL DESIGN The results are similar to the full factorial design as the most significant factor is the stop angle followed by arm length and start angle. CONCLUSION I would recommend the full factorial. As by having only 16 data points, we already have cut down the number of runs to 2 each. So the data is already not as reliable. If we did fractional factorial, it might not give enough data for us to get accurate analysis and the right interactions. Furthermore, doing a full factorial for 16 data points is not considerably difficult, hence there should be no issues with doing the full factorial.
