Which section of the report allows a nurse researcher to review critical summary numbers for each test?
Methods.
Results.
Literature review.
Discussion.
The Correct Answer is B
Choice A rationale
The methods section details the study design, setting, sample characteristics, and data collection procedures used by the researcher. It explains how the study was conducted so that other scientists can evaluate its rigor or replicate the findings. While it may mention the statistical tests intended for use, it does not contain the actual data, summary numbers, or the final results of those tests. It focuses on the process rather than the final quantitative output.
Choice B rationale
The results section is dedicated to presenting the data collected and the outcomes of statistical analyses. This is where researchers provide critical summary numbers, such as p-values, mean scores, standard deviations, and correlation coefficients. For example, a p-value < 0.05 typically indicates statistical significance. This section focuses purely on the findings without interpretation, allowing the reader to see the raw mathematical evidence generated by the tests performed during the study.
Choice C rationale
The literature review provides a comprehensive summary of existing research and knowledge related to the study topic. It identifies gaps in current evidence and provides the background necessary to justify the current investigation. While it may discuss summary numbers from previous studies conducted by other authors, it does not report the specific data or statistical test results produced by the current study being described in the report. Its role is strictly contextual and foundational.
Choice D rationale
The discussion section interprets the results and explains their clinical or theoretical significance. It compares the findings to existing literature and discusses limitations and implications for future practice. While the discussion references the results, it focuses on the meaning behind the numbers rather than providing the primary report of summary statistics. It transitions from the quantitative data found in the results section to a qualitative interpretation of what those findings mean for nursing.

Correct Answer is D
Explanation
Choice D rationale
Reliability refers to the degree to which a research instrument produces stable and consistent results over time when administered repeatedly under the same conditions. If a tool yields the same data every time it is used on the same subject, it is considered reliable. This is essential for ensuring that the findings are not due to random error or fluctuations in the measurement process. Reliability is often measured using coefficients like Cronbach's alpha, where a value ≥ 0.70 is standard.
Choice A rationale
Predictability is a concept often related to the ability of a study or model to forecast future outcomes based on current data. While a reliable instrument provides a stable base for making predictions, the term itself does not define the consistency of a measurement tool. In research terminology, we focus on whether the tool measures the same thing consistently, which is reliability, rather than the predictive power of the results themselves. Predictability is more relevant to longitudinal trends.
Choice B rationale
Validity refers to the extent to which an instrument actually measures what it is intended to measure. A scale might be highly reliable, giving the same weight every time, but if it is not calibrated correctly, it is not valid. While reliability and validity are related, they are distinct concepts. A tool must be reliable to be valid, but a reliable tool is not automatically valid. Validity ensures the accuracy of the data in relation to the specific construct.
Choice C rationale
Consistency is a descriptive term often used synonymously with reliability in general conversation. However, in the formal language of nursing research and statistics, reliability is the specific technical term used to describe the stability of an instrument. While a reliable instrument is consistent, the correct scientific classification for an instrument that obtains the same results upon repeated administration is reliability. Using the precise term is necessary for professional critique and methodological reporting in clinical research studies.
Correct Answer is A
Explanation
Choice A rationale
A professional critique of a quantitative research report involves a balanced and objective evaluation of the study's strengths and weaknesses. The critic examines the logic of the problem statement, the appropriateness of the design, the rigor of the methods, and the validity of the conclusions. This process is not merely about finding faults but about determining the overall quality and utility of the evidence. It requires a deep understanding of the research process to judge scientific merit.
Choice B rationale
Summarizing the major steps of the research process is a descriptive task often done in the initial phase of a review, but it does not constitute a critique. A critique must go beyond a simple summary to provide an analytical judgment of how well those steps were executed. Merely repeating what the researcher did does not evaluate the quality of the work or its contribution to the field of nursing science. Critiquing requires critical thinking and appraisal.
Choice C rationale
Applying findings in clinical practice is the goal of evidence-based practice and follows the critique process, but it is not the critique itself. Before findings can be applied, they must be rigorously evaluated for their validity and reliability. If a nurse skips the critique and goes straight to application, they risk implementing interventions based on flawed or weak evidence. The critique serves as the essential filter that determines if the research is robust enough for implementation.
Choice D rationale
Determining if a phenomenon is recognized by participants as their own is a criterion for evaluating the credibility of qualitative research, often called member checking. In quantitative research, the focus is on objective measurement and statistical significance rather than participant validation of the results. Quantitative reports are critiqued based on internal and external validity, instrument reliability, and the appropriateness of the statistical tests used, which are entirely different standards than those used in qualitative paradigms.
