1. Analysis by SAS Interaction Plot by Excel
Three-Way ANOVA
Analysis by SAS
Interaction Plot by Excel

2. The Design Type of Crime: Burglary or Swindle
Culture of Defendant: American or Chinese
Sex of Juror: Female or Male
DV: Recommended length of sentence

3. Read in the Data Data JurySimulation;
Infile 'C:\Users\Vati\Documents\SimData\ANOVA3B-13.dat';
Input Culture $ Crime $ Sex $ Sentence;

4. Omnibus Analysis Proc ANOVA; Class Sex Culture Crime;
Model Sentence = Sex|Culture|Crime;
Means Sex|Culture|Crime; run;

5. Results & Follow-Up The triple interaction is significant
Conduct simple interaction analysis
Test Culture x Crime for each sex
I asked you to do the simple interaction analysis even if the triple interaction was not significant

6. Simple Interaction Effects
Proc Sort; By Sex;
Proc ANOVA;
Class Culture Crime;
Model Sentence = Culture|Crime;
By Sex; run;

7. Results & Follow-Up
For each simple interaction that is significant, test the simple, simple main effects.
Effect of type of crime at given levels of culture and sex.
I asked you to do these tests regardless of whether or not the simple interaction was significant

8. Simple, Simple Main Effects
Proc Sort; By Sex Culture;
Proc ANOVA; Class Crime;
Model Sentence = Crime;
By Sex Culture; run;

9. The Comparisons Made
Compare length of sentence for burglars versus swindlers when
Juror is female, defendant is American
Juror is female, defendant is Chinese
Juror is male, defendant is American
Juror is male, defendant is Chinese

10. Prepare an Interaction Plot
Enter the appropriate means into Excel (2010)
These are for the female jurors

11. Insert, Charts, Line

12. Select “Line With Markers”

13. Tweak the Vertical Axis

14. Gee Whiz

15. Add Axis Titles

16. Enter Text in Title Box
Then do the same for the Vertical Axis

17. Enter Chart Title

18. Other Tweaks Resize the chart Change fonts Remove or change grid lines
Et cetera
Then copy the chart to Word, PowerPoint, or other application.

20. Prepare the Second Plot
We need a plot for the male jurors too.
Enter the appropriate data into Excel.
Tweak the plot so it has the same dimensions as the previous plot.
If you do not, Excel may scale it in a way that distorts the differences between the two plots.
