1) (2) In Experiment A, there are three treatment conditions with M = 5, M2 = 10, and M3 = 15. In Experiment B, there are three treatment conditions with M1 = 8, M2 = 10, and M3 = 12. Assume that the samples sizes in both experiments are the same. Which experiment has a greater value for MS between? (You don't have enough information to compute precise answers.) a. b. d. there's not enough information to decide Experiment A Experiment B they have the same MSbetween C. 2) (2) When the null hypothesis is true in a one-factor ANOVA, the expected value for Fots is d. the critical value of F 2.0 b. 1 c. much greater than 1 3) (2) In an ANOVA, which of the following is most likely to produce a large value for the F-ratio? a. large mean differences and large sample (group) variances b. large mean differences and small sample (group) variances small mean differences and large sample (group) variances d. small mean differences and small sample (group) variances 4) (2) Pearson's correlation coefficient (r) for the data depicted in the scatterplot at right would be d between 0&-1 exactly - 1 a. exactly +1 b. between 0& +1 exactly o

Answer 1

Ans 1: the correct ans is Experiment A because MS between measures variability between group means and group means for experiment A are more scattered

Ans 2 When the null is true, the expected value for the F-ratio is 1.00 because the top and bottom of the ratio are both measuring the same variance
