2×3 Experimental Room Color Study and Repeated Measures Analysis

2×3 Experimental Room Color Study and Repeated Measures Analysis

A 2×3 experimental study was conducted to examine the degree to which Room Color affects learning across two different class Topics. The data are provided on the next page. Three room colors 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 I
Analyze 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 the interaction by checking “descriptive statistics” → CONTINUE → OK]

Part II
Analyze 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.

[After data entry: Analyze → General Linear Model → Repeated Measures → Define the independent variables (enter levels) → Define: Highlight appropriate column [on left] to match expected label [on right] and press arrow to move it over → Under “options” you can have it display means for the interaction by checking “descriptive statistics” → CONTINUE → OK]
