Evaluating Research for
Practice
Pre - Assessment Guide
Q&S
2024
,1. What is the primary purpose of a systematic review in evidence-based
practice?
- A) To provide a summary of literature
- B) To evaluate the quality of research studies
- C) To establish clinical practice guidelines
- D) To identify gaps in research
Answer: C) To establish clinical practice guidelines
Rationale: Systematic reviews synthesize findings from multiple studies
to inform practice guidelines.
2. In a randomized controlled trial (RCT), what does blinding refer to?
- A) The use of placebos
- B) Keeping participants unaware of the group allocation
- C) The statistical analysis method
- D) The process of randomization
Answer: B) Keeping participants unaware of the group allocation
Rationale: Blinding minimizes bias by preventing participants from
knowing which intervention they receive.
3. Which of the following best describes internal validity?
- A) The extent to which results can be generalized to other settings
, - B) The accuracy of measurements within the study
- C) The degree to which the study results are attributable to the
intervention
- D) The consistency of results across different populations
Answer: C) The degree to which the study results are attributable to
the intervention
Rationale: Internal validity indicates how well the study demonstrates a
causal relationship between variables.
4. What is a confounding variable?
- A) A variable that is held constant throughout the study
- B) A variable that the researcher manipulates
- C) An extraneous variable that correlates with both the dependent
and independent variables
- D) The outcome variable of interest
Answer: C) An extraneous variable that correlates with both the
dependent and independent variables
Rationale: Confounders can provide alternative explanations for the
observed relationships in a study.
5. In qualitative research, what is the role of thematic analysis?
- A) To quantify the frequency of themes
- B) To identify patterns within the data
, - C) To test hypotheses
- D) To determine cause-and-effect relationships
Answer: B) To identify patterns within the data
Rationale: Thematic analysis is used to interpret and make sense of
qualitative data by identifying recurring themes.
6. What does 'peer review' in the context of research publication ensure?
- A) The article is free of plagiarism
- B) The research is funded by reputable sources
- C) The study findings are statistically significant
- D) The research meets academic and ethical standards
Answer: D) The research meets academic and ethical standards
Rationale: Peer review is a quality control process where experts
evaluate the research for its rigor and integrity.
7. Which statistical test would be most appropriate for comparing mean
blood pressure readings between two independent groups?
- A) Chi-square test
- B) T-test
- C) ANOVA
- D) Regression analysis
Answer: B) T-test
