For which reason do many researchers prefer to write a hypothesis as a directional hypothesis?
 
  1. The use of the null hypothesis in a study demonstrates the researcher's lack of critical thought about the phenomenon under study.
  2. It clarifies the study's framework and demonstrates that the researcher has thought critically about the phenomenon under study.
  3. A research hypothesis should not specify the proposed relationship between the study variables.
  4. Occasionally the researcher writes a research hypothesis, which is the same as the null hypothesis.

Question 2

Which hypothesis is correctly stated?
 
  1. There will be a positive relationship between the amount of time nurses spend in patient rooms and the number of times patients use their call lights.
  2. Nurses' level of job satisfaction will influence their length of employment.
  3. Patients who use guided imagery have less pain than patients who do not use guided imagery.
  4. Is there a relationship between anxiety and ability to learn in new graduate nurses during their orientation?

Answer to Question 1

2
Rationale 1: Some researchers write hypotheses in the null form, but this does not mean that the researcher has not thoughtfully considered the relationship of the variables. The null hypothesis is always tested in experimental studies, no matter how the study hypothesis is written.
Rationale 2: A directional hypothesis is preferred when there is a reasonable basis to predict the relationship between the variables that is based on the researcher's critical thought and analysis of the phenomenon under study.
Rationale 3: The hypothesis should predict the relationship between the variables.
Rationale 4: The null hypothesis predicts that there is no relationship between the study variables. The research hypothesis states the predicted relationship. They are not the same.
Global Rationale:

Answer to Question 2

3
Rationale 1: This statement is written in future tense. Hypotheses are written in present tense.
Rationale 2: This hypothesis is not empirically testable as written. What does will influence mean?
Rationale 3: This hypothesis is written in the present tense, is empirically testable, and contains the variable and the population.
Rationale 4: Hypotheses are written as declarative statements, not questions.
