Homework Assignment Week 8 PSY/CJ 315 Due 6/4/17 1. Calculate SStotal, SSbetween, and SSwithin for the following set of data: Treatment 1 n = 10 T = 10 SS = 27 2. Name: ________________________ Treatment 2 n = 10 T = 20 SS = 16 Treatment 3 n = 10 T = 30 SS = 23 N = 30 G = 60 X2 = 206 The following values are from an independent-measures study comparing three treatment conditions. Treatment I II III n=8 n=8 n=8 SS = 35 SS = 42 SS = 70 a. b. Compute the variance for each sample. Compute MSwithin, which would be the denominator of the F-ratio for an ANOVA. Because the samples are all the same size, you should find that MSwithin is equal to the average of the three sample variances. 3. The following data were obtained from an independent-measures study comparing three treatment conditions. I n=6 M=1 SS = 60 a. b. 4. Treatment II n=6 M=2 SS = 65 III n=6 M=6 SS = 40 N = 18 G = 54 X2 = 411 Calculate the sample variance for each of the three samples. Use an ANOVA with = .05 to determine whether there are any significant differences among the three treatment means. (Note: In the ANOVA you should find that MSwithin is equal to the average of the three sample variances.) The following summary table presents the results from an ANOVA comparing four treatment conditions with n = 10 participants in each condition. Complete all missing values. (Hint: Start with the df column.) Source SS df MS Between Treatments _____ _____ 10 Within Treatments _____ _____ _____ Total 174 _____ 5. F = _____ The following scores are from an independent-measures study comparing two treatment conditions. Treatment I 10 8 7 9 13 7 6 12 _______________________ a. b. Treatment II 7 4 9 3 7 6 10 2 N = 16 G = 120 X2 = 1036 __ Use an independent-measures t test with = .05 to determine whether there is a significant mean difference between the two treatments. Use an ANOVA with = .05 to determine whether there is a significant mean difference between the two treatments. You should find that F = r2. 6. A published report of a repeated-measures research study includes the following description of the statistical analysis. \"The results show significant differences among the treatment conditions, F(2,26) = 4.87, pStep by Step Solution
