Complex Designs
1. (p. 247, 250) Distinguish between a main effect and an interaction effect in a complex design.
The overall effect of one independent variable in a complex design is called a main effect. An
interaction effect in a complex design occurs when the effect of one independent variable
differs depending on the level of a second independent variable.
2. (p. 257, 259-260) Briefly describe the analysis that are done to interpret the results of complex
designs when an interaction effect is present and when an interaction effect is not present.
