Q.6 Which of the following is NOT a source for generating a hypothesis?
Review of literature
Research problem
Personal beliefs without evidence
Observation of clinical practice
Explanation - Hypotheses should be based on evidence or theory, not solely on personal opinion.
Correct answer is: Personal beliefs without evidence
Q.7 Which type of hypothesis is formulated after data collection and analysis?
Working hypothesis
Post hoc hypothesis
Research hypothesis
Null hypothesis
Explanation - A post hoc hypothesis is generated after analyzing data, often to explain unexpected findings.
Correct answer is: Post hoc hypothesis
Q.8 Which hypothesis would be used to test the effect of two variables without specifying the direction?
Directional hypothesis
Non-directional hypothesis
Null hypothesis
Alternative hypothesis
Explanation - A non-directional hypothesis predicts a relationship exists but does not specify whether it is positive or negative.
Correct answer is: Non-directional hypothesis
Q.9 What is the relationship between null and alternative hypotheses?
Both predict no relationship
They are mutually exclusive
Both are directional
They are unrelated
Explanation - If the null hypothesis is rejected, the alternative hypothesis is accepted, showing they are mutually exclusive.
Correct answer is: They are mutually exclusive
Q.10 Which component is essential in a testable hypothesis?
Abstract theory
Operational definition of variables
Author's opinion
Background history
Explanation - Variables must be clearly defined in measurable terms to make the hypothesis testable.
Correct answer is: Operational definition of variables
Q.11 Which of the following best defines a research hypothesis in nursing?
A proven fact about nursing practice
A tentative statement predicting a relationship between variables
An assumption based on personal experience
A summary of research findings
Explanation - A research hypothesis is a statement that predicts an expected relationship between variables to guide the study.
Correct answer is: A tentative statement predicting a relationship between variables
Q.12 Why is it important for a hypothesis to be specific?
To make it difficult to test
To ensure it can be clearly tested and measured
To allow personal interpretation
To avoid using variables
Explanation - Specificity allows operational definitions and precise testing of variables.
Correct answer is: To ensure it can be clearly tested and measured
Q.13 Which type of hypothesis predicts a difference or effect between groups?
Research hypothesis
Null hypothesis
Post hoc hypothesis
Statistical hypothesis
Explanation - A research hypothesis predicts a relationship or difference that can be empirically tested between variables or groups.
Correct answer is: Research hypothesis
Q.14 Which hypothesis is often used in experimental research?
Null hypothesis
Directional hypothesis
Non-directional hypothesis
All of the above
Explanation - Experimental research may use null, directional, or non-directional hypotheses depending on the study design.
Correct answer is: All of the above
Q.15 A hypothesis should be __________ to allow empirical testing.
Subjective
Falsifiable
Vague
General
Explanation - A falsifiable hypothesis can be tested and potentially proven false through evidence, making it scientifically valid.
Correct answer is: Falsifiable
Q.16 Which of the following is an example of a null hypothesis?
There is no difference in patient satisfaction between hospitals using traditional and modern nursing methods.
Higher nursing experience leads to better patient outcomes.
Stress negatively affects nurse performance.
Increased training improves knowledge scores.
Explanation - The null hypothesis predicts no relationship or difference between variables.
Correct answer is: There is no difference in patient satisfaction between hospitals using traditional and modern nursing methods.
Q.17 Which of the following is an example of a directional hypothesis?
Nurses with higher education levels demonstrate higher patient care competency.
There is a difference in patient recovery times between two hospitals.
There is no relationship between nurse experience and patient satisfaction.
All nurses work in shifts.
Explanation - A directional hypothesis specifies not only the existence but also the expected direction of the relationship.
Correct answer is: Nurses with higher education levels demonstrate higher patient care competency.
Q.18 Formulating a hypothesis is important because it:
Eliminates the need for a research question
Provides direction for data collection and analysis
Replaces literature review
Is optional in qualitative research
Explanation - The hypothesis guides the study by specifying what relationships to examine and measure.
Correct answer is: Provides direction for data collection and analysis
Q.19 Which of the following best describes a testable hypothesis?
One that can be evaluated using scientific methods
One that cannot be measured
One based solely on theory without operational definitions
