Full Factorial Data Analysis › Determine the effect of single factors and their ranking. Figure 1: Graph of Full Factorial Data Legend: Factor A : Arm Length. This affects the amount of energy that is provided to the projectile where shorter arm length provides more energy for the projectile to go further. Factor B : Projectile weight. The weight of the projectile determines the amount of energy that is required for the projectile to fly. A lower amount of weight would mean a lower amount of energy is needed for the projectile to go further. Factor C : Stop angle. The angle at which the arm is launched at will affect the amount of energy that is provided to the projectile. A smaller stop angle from the ground will provide more energy for the projectile to go further. Ranking: 1. Factor C 2. Factor A 3. Factor B › Determine the interaction effects Figure 2: Interaction effect of A x B Both lines have a significant positive gradient and are at different values. Hence, there is a si
