(Solved by Humans)-B. Consider Elliot and colleagues' (2007) study on the color

Paper Details

B. Consider Elliot and colleagues? (2007) study on the color red and performance at ?????????????????????? academic tasks, discussed in Chapter 8. Design a new version of that study, adding a new independent variable to create a factorial design. Indicate the notation for the design (using the ?__ x __? formdddffdat) and create a graph of the results you would predict in Excel. Indicate how you would manipulate each variable. Finally, based on the graph you have created, indicate which main effects and interactions are likely to be significant. (If you prefer, you can draw the graph instead of creating it in Excel. If you choose to do this, please leave your work in the box outside my office.)

C. Imagine a design with two independent variables, A and B. A has two levels and B has three levels.

This is a 2 x 3 design, with levels: A₁, A₂ and B₁, B₂, B₃

a. In Excel (or by hand), create a graph with a main effect for A, a main effect for B, but no interaction.

b. Create a graph with no main effect for A, a main effect for B, and an interaction.

c. Create a graph with a main effect for A, no main effect for B, and no interaction.
