For a two-factor experiment with 2 levels of factor A and 3 levels of factor B and n = 5 subjects in each treatment condition, how many participants are in one level (i.e. row) of factor A? On = 30 n = 10 On=5 On = 15

A two-factor research study is used to evaluate the effectiveness of a new blood- pressure medication. In this two-factor study, Factor Ais 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. Which pattern of results should be obtained if the medication works as predicted? a significant main effect for factor A (medication) The answer is not provided. a significant interaction O a significant main effect for factor A and a significant interaction

For an independent-measures experiment, the F-ratio is 4.1. If dfbetween = 2, and dfwithin = 12, the researcher... fails to reject the null both with a = .01 and a = .05. rejects the null both with a = .01 and a = .05. rejects the null with a = .01, but not with a = .05. O rejects the null with a = .05, but not with a = .01.

A two-factor research study has 3 levels of factor A and 3 levels of factor B with n = 8 participants in each treatment condition. For this study, what is the value for df between treatments? O 3 O 8 9 5
