The researcher has reported a one-tailed analysis of variance to test the hypothesis, "Nurse intervention plus group sessions is more effective than nurse intervention alone or community intervention in improving Framingham coronary risk scores among rural dwelling women in the Promoting Heart Health in Rural Women study." Why is the choice of a one-tailed test versus a two-tailed test
appropriate?
1. It is easier to reject the null hypothesis using a two-tailed test.
2. There is only one true variable in this study.
3. The researcher has stated a directional research hypothesis.
4. The nurse wishes to develop a theoretical framework for further study.

Rationale 1: It is easier to reject the null hypothesis using a one-tailed test.
Rationale 2: There is more than one variable in this study.
Rationale 3: This is an appropriate use of a one-tailed test.
Rationale 4: This is a directional research hypothesis, which requires that a strong theoretical framework already be in place, not one that is being developed.
