Document Summary
Research methods for the behavioral sciences chapter 11. Factorial experimental designs - experimental design with more than one independent variable: factor - refers to each of the manipulated iv, cells - conditions or levels. The two main effects give researcher all the information that would"ve been provided if they conducted two separate one-way experiments. Main effects test influence of each iv. Interaction - a pattern of means that may occur in a factorial experimental design when the influence of one iv on the dv is different at different levels of another iv. Simple effect - the effect of one factor within a level of another factor. Anova summary table: presents f values and significance tests, similar to one-way design, but there are f values for each of the main effects and interactions. Understanding interactions: patterns of observed means. Predictions always stated in the form of expected main effects and interactions.
