Document Summary
2 x 2 factorial design: more than one independent variable. Chapter 8 notes a. i. can look at the effects on dependent variable separately a. ii. find interactions: 2 levels of one iv, 2 levels of other iv c. the ivs are also called factors . Imagine we want to study two factors and their effects on movie enjoyment a: dv: how much enjoyed movie, one factor = gender, another factor = movie type. In analyzing the outcome of any factorial design, we are interested in two major questions: a. i. Does either iv have treatment effect? a. i. 1. a. i. 2. Interpretation of subject variables within factorial designs: subject variable: relatively permanent, subject variable + randomly assigned iv b. i. Effect of attendance in motivated vs. unmotivated b. ii. 4. 9 poorly b. v. 7. 51 male b. vi. 7. 475 - female b. vii. y axis rating of intelligence b. viii. x axis preparedness: anytime we have slopes that are not exactly the same, we have an interaction.
