Hays (5 th ed) p. 520 A study involved children of three age groups: A1=5yrs, A2= 6 years, A3 = 7 years. Second Factor was formal preschool experience B1=none, B2=1 year, B3 = more than 1 year Five children were sampled from each combination and given a score on ‘social maturity’ (high scores are more mature)
B1B2B3 A A11085 A19103 A A A29710 A28812 A A A A3106 A3149
Enter the data into SAS Print the data to be sure they are correct Be sure the data are arranged in the way SAS needs to analyze the problem
Run a 2-Way ANOVA on the data What terms are significant What is the interpretation at the level of main effects and interactions from the printout?
Graph the means What is the interpretation of the means according to the graph? You can use a program other than SAS for the graph if you want.
What is the magnitude of effect What is R-square for A, B, and A*B? What is estimated omega-squared for each?
