The Best Experimental Design For Determining Interactions Is A. If you add a medium level of TV violence to your design then you have a 3 x 2 factorial design. 4 FACTORIAL DESIGNS 41 Two Factor Factorial Designs A two-factor factorial design is an experimental design in which data is collected for all possible combinations of the levels of the two factors of interest.
4 FACTORIAL DESIGNS 41 Two Factor Factorial Designs A two-factor factorial design is an experimental design in which data is collected for all possible combinations of the levels of the two factors of interest. If equal sample sizes are taken for each of the possible factor combinations then the design is a balanced two-factor factorial design. A factorial design is used when researchers are interested in the interaction effects between multiple independent variables.
Each of the graphs below Plots 1-8 depicts a different situation with regard to the main effects of the two independent variables and their interaction.
The best way to understand these effects is with a special type of graphan interaction plot. An experimental design is a planned experiment to determine using a minimum number of experimental runs what factors have a significant effect on a product response andor variability in the product response and how large the effect is in order to find the optimum set of operating conditions. If you add a medium level of TV violence to your design then you have a 3 x 2 factorial design. But two-factor interactions are aliased with three-factor interactions 5-23.
