A two-factor ANOVA produces an F-ratio for factor A with df = 1, 36 and an F-ratio for factor B with df = 2, 36. Which of the following describes the experiment producing these F-ratios?

Select one:

a. 1 level of factor A and 2 levels of factor B

b. 2 levels of factor A and 3 levels of factor B

c. 2 levels for both factors

d. 3 levels for both factors

A two-factor research study is used to evaluate the effectiveness of a new blood-pressure medication. In this two-factor study, Factor A is medication versus no medication and factor B is male versus female. The medicine is expected to reduce blood pressure for both males and females, but it is expected to have a much greater effect for males. What pattern of results should be obtained if the medication works as predicted?

Select one:

a. A significant main effect for factor A (medication)

b. A significant interaction

c. A significant main effect for factor A and a significant interaction

d. None of the above

A two-factor, independent-measures research study is evaluated using an analysis of variance. The F-ratio for factor A has df = 1, 40 and the F-ratio for factor B has df = 3, 40. Based on this information, what are the df values for the AxB interaction?

Select one:

a. df = 2, 40

b. df = 3, 40

c. df = 4, 40

d. df = 7, 40

For a two-factor experiment with 2 levels of factor A and 3 levels of factor B and n = 10 subjects in each treatment condition, how many participants are in each level of factor A?

Select one:

a. 10

b. 20

c. 30

d. 60

For a two-factor study with 2 levels of factor A, 2...
