A 2 x 3 x 4 factorial design has _____ potential main effects. 2 3 4...
In a factorial design, a significant interaction effect means none of the main effects can be significant True or False?
1 How many experiment runs are there in a 3 x 4 x 2 factorial design? Runs in 3x4x3x2 factorial design? 2 If 3 variables are studied using 3 levels, how to designate the design and number of experiment runs will it require? and 6 variables at 2 levels?
A 2^3 factorial is replicated twice. The ANOVA indicates that all main effects are significant but the interactions are not significant. The interaction terms are dropped from the model. The number of residual degrees of freedom for the reduced model is
QUESTION 42 Make up an example of a study that uses a 2 x 2 factorial design, and fill in a table of cell means that would show no main effects and no interaction effect. (Do not use an example from your textbook class lectures, or your classmates.) Explain the pattern of the cell means you created within the context of your example.

Lesson: -Factorial designs have more than one independent variable or factors. -A two way factorial design has two independent variables, a three-way factorial design has three independent variables and so forth. -A 2x2 design has two factors and two levels of each. -A 2x3 design also has two factors but one has two levels and one has three. -A 3x3 design has two factors and each factor has 3 levels. Each example has 2 independent variables or factors. Comparison of...
Chapter 10 Questions 11. What is a factorial research design? Give two advantages of a factorial research design over doing two separate studies. 12. In a factorial design, what is a main effect? What is an interaction effect? 13. Answer the following questions with the results for a fictional study of the effects of vividness and length of examples (the grouping variables) on number of examples recalled (the measured variable). Vividness Short Long Overall Describe the pattern of results in...

These results show 100 A1 50 A2 a. there is a significant main effect for factor A, no other significant effects b. there is a significant main effect for factor B, no other significant effects c. there is a significant interaction effect, no other significant effects d. there is a significant main effect for factor A, a significant interaction effect, and no other significant effects e. there is...
Present an outcome matrix that demonstrates two main effects in a 2 x 2 design.
QUESTION 44 In a two way ANOVA, how many effects (main effects and interaction) are tested? a. 4 b. 1 c. 3 d. 2 2 points QUESTION 45 Main effects are defined as the effect of ______. a. one independent variable on the dependent variable that changes at the different levels of another independent variable b. the dependent variable on the independent variable within a factorial research design c. an independent variable on the dependent variable within a factorial...
Factorial Design (DOE) An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 23 factorial design are run. The results show the averages of the three replicates: A B C Mean - - - 26.00 + - - 34.67 - + - 39.67 + + - 49.33 - - + 42.33...
