1. PSY 1950 Repeated-Measures ANOVA October 27, 2008

2. Midterm Mean = 18.5, SD = 3.33 Lower inner fence = 11

5. Independent/Dependent-Measures Independent-measures –Different sample for each condition –e.g., meditators vs. non-meditators –Scores from one condition do not predict (correlate with) scores from another condition Dependent-measures/Repeated-measures –Same sample for each condition –e.g., pre-meditation, post-meditation –Scores from one condition do predict (correlate with) scores from another condition

6. Advantage of Repeated-Measures Each subject serves as his/her own control Individual, “baseline” differences cannot explain observed differences between condition means Reduced noise in the system, error variance Reduced denominator of F-ratio
