A Research Project Studied the Physical Properties of Wood Materials

question 29

Multiple Choice

A research project studied the physical properties of wood materials constructed by bonding together small flakes of wood.The two factors considered were the size of the flakes and species of tree.The sizes of the flakes were S1: 0.15 inches by 2 inches and S2: 0.25 inches by 2 inches,and the species of tree used were aspen,birch,and maple.For each combination of flake size and tree species,three samples of wood material were constructed.For each sample,the physical property measured was the tension modulus of elasticity in the direction perpendicular to the alignment of the flakes,in pounds per square inch (psi) .Which statement best describes the type of experiment being run?

• A)This is a two-factor experiment.Each factor is at three levels.
• B)This is a six-level experiment.Each level has three observations.
• C)This is a two-factor experiment.One factor is at two levels,and the other factor is at three levels.
• D)None of the above
