An independent-measures t test produced a t statistic with df = 20

Question 1   An independent-measures t test produced a t statistic with df = 20. If the same data had been evaluated with an analysis of variance, what would be the df values for the F-ratio? Answer a. 1, 20 b. 2, 20 c. 1, 19 d. 2, 19 Question 2   An analysis of variance comparing three treatment conditions produces dftotal = 24. For this ANOVA, what is the value of dfwithin? Answer a. 3 b. 2 c. 21 d. 22 Question 3   A researcher uses analysis of variance to test for mean differences among four treatments with a sample of n = 6 in each treatment. The F-ratio for this analysis would have what df values? Answer a. df = 3, 15 b. df = 4, 24 c. df = 3, 5 d. df = 3, 20 Question 4   For an analysis of variance comparing four treatments, MSbetween = 12. What is the value of SSbetween? Answer a. 4 b. 48 c. 36 d. 3 Question 5   An analysis of variance produces SSwithin = 40 and MSwithin = 10. In this analysis, how many treatment conditions are being compared? Answer a. 4 b. 5 c. 50 d. 30 Question 6   An analysis of variance comparing three treatment conditions produces dftotal = 24. For this ANOVA, what is the value of dfbetween? Answer a. 2 b. 3 c. 22 d. 21 Question 7   An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this study, the three sample totals are, T1 = 5, T2 = 10, and T3 = 15. What value would be obtained for SSbetween? Answer a. 15 b. 5 c. 1 d. 10 Question 8   An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this study, the three sample totals are, T1 = 5, T2 = 10, T3 = 15, and 2 = 75 for the entire set of scores. What value would be obtained for SStotal? Answer a. 15 b. 5 c. 10 d. 1
