Univariate Analysis
Hicks Design of Experiment Example: Layout
Raw Data Pre: Check on Randomization
Raw Data Post: Check for Trt Effect
Refined Plots for Pre Scores
Can actually test Randomization with Pre scores
Refined Plots for Post Scores
Univariate Analysis Repeated Measures
Have two error terms: S(G) and T*S(G)
Suppose Subject was deleted from the analysis
Model with Group and Test and Interaction
So what happened?
 When we drop terms from the model they go into…
 If we drop two terms from the model they go into…
 Since we now have only one error term, it is the
combination of…
 So for some F-tests it is…
 For other F-tests it is…
 The means of those Main Effects and Interaction have
not changed. but what did change was…
LS Means Plot Group
Interaction Plot
Tukey HSD on Interaction (be careful about the
letters in JMP)
What if we only look at paired differences?
ANOVA on Paired Score Differences
Tukey HSD
Since a true Control Group exists, use Dunnett’s
