A 2×3 experimental study was conducted to examine the degree to which Room Color affectslearning across two different class Topics. The data are provided on the next page. Three roomcolors were used (red, green, and blue) and performance was assessed across two class topics(math and history). Learning was measured by inspecting final exam scores.
Part IAnalyze the data as though the design was a 2×3 between-subjects (independent groups)
design in which N = 120. You will find pages 410-414 in your text to be helpful with this.
[After data entry: Analyze †’ General Linear Model †’ Univariate †’ Select dependent variable &the “fixed factors” (independent variables) to analyze †’ Under “options” you can get means for theinteraction by checking “descriptive statistics” †’ CONTINUE †’ OK]
Part IIAnalyze the data as though the design was a 2×3 within-subjects (repeated measures) design
in which N = 20. Again, pages 410-414 of your text will be helpful.
