Question 1
What is the correct definition of validity in research measurement?
A. The consistency of results over time
B. The extent to which an instrument measures what it is intended to measure
C. The ease of administering a research tool
D. The number of items in a questionnaire
Correct Answer: B. The extent to which an instrument measures what it is
intended to measure
Rationale: Validity refers to how accurately an instrument reflects the concept being
studied. Reliability (A) is consistency over time, not accuracy. Ease of use (C) and
number of items (D) do not define validity.
Question 2
What question best assesses content validity of a research instrument?
A. Does the instrument produce consistent results?
B. Do the items reflect what is being measured?
C. Is the instrument easy to score?
D. Does it reduce researcher bias?
Correct Answer: B. Do the items reflect what is being measured?
Rationale: Content validity ensures items fully represent the concept. Consistency (A)
is reliability, not validity. Ease of scoring (C) and bias reduction (D) are unrelated.
Question 3
What is the test-retest method used to assess?
A. Validity
B. Reliability
C. Sampling error
D. Content accuracy
Correct Answer: B. Reliability
,2026/2027
Rationale: Test-retest measures stability over time. Validity (A) is accuracy, not
consistency. Sampling error (C) and content accuracy (D) are unrelated.
Question 4
Which statement best defines reliability?
A. The degree to which a tool measures the correct concept
B. The consistency of results over repeated measurements
C. The ability to generalize findings
D. The clarity of questionnaire items
Correct Answer: B. The consistency of results over repeated measurements
Rationale: Reliability refers to consistency. Validity (A) is accuracy. Generalization
(C) relates to external validity, and clarity (D) is instrument design.
Question 5
Which qualitative method is best for developing an intervention to reduce youth
tobacco use?
A. Phenomenology
B. Ethnography
C. Community-based participatory research
D. Case study
Correct Answer: C. Community-based participatory research
Rationale: This approach involves communities in creating solutions. Phenomenology
(A) explores lived experience. Ethnography (B) studies culture. Case studies (D)
focus on single cases.
Question 6
Which situation is best studied using qualitative research?
A. Blood pressure trends in adults
B. Drug effectiveness comparison
C. Lived experience of losing a parent to HIV/AIDS
D. Incidence of diabetes in a population
Correct Answer: C. Lived experience of losing a parent to HIV/AIDS
Rationale: Qualitative research explores lived experiences. The others involve
measurable quantitative data.
Question 7
, 2026/2027
What is the level of evidence for a single qualitative study?
A. Level 1
B. Level 3
C. Level 5
D. Level 6
Correct Answer: D. Level 6
Rationale: Single qualitative studies are lower in evidence hierarchy. Higher levels
involve systematic reviews or meta-analyses.
Question 8
In qualitative research, participants are referred to as:
A. Subjects
B. Respondents
C. Participants
D. Samples
Correct Answer: C. Participants
Rationale: Qualitative research uses “participants” to reflect active involvement.
“Subjects” is quantitative terminology.
Question 9
What conclusion suggests a qualitative study?
A. Statistical correlation between variables
B. Themes about experiences in diabetes management
C. Blood glucose averages
D. Randomized trial outcomes
Correct Answer: B. Themes about experiences in diabetes management
Rationale: Themes reflect qualitative analysis. The others are quantitative measures.
Question 10
Which best describes ethnographic research?
A. Focuses on statistical testing
B. Studies lived experiences
C. Studies culture using emic and etic perspectives
D. Tests hypotheses
Correct Answer: C. Studies culture using emic and etic perspectives
Rationale: Ethnography examines cultural meaning from insider and outsider views.
