In the discussion, the researcher presents conclusions about the meaning and implications of the findings, i.e., what the results mean, why things turned out the way they did, how the findings fit with other evidence, and how the results can be used in practice.

The criterion used by quantitative researchers involving the soundness of the evidence is which of the following? A) Reliability B) Validity C) Credibility D) Generalizability

Ans: B Validity is a more complex concept that broadly concerns the soundness of the study's evidenceóthat is, whether the findings are cogent, convincing, and well grounded. Reliability (a key challenge in quantitative research) refers to the accuracy and consistency of information obtained in a study. Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretations. Generalizability in a quantitative study concerns the extent to which the findings can be applied to other groups and settings.

Ans: C An inference is a conclusion drawn from evidence presented in the research study. Statistically significant means that the study has a high probability of being ìreal.î Validity is the soundness of the study. Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretation.

In a qualitative research article, the thematic analysis of the data would be presented in which section? A) Introduction B) Method section C) Results section D) Discussion section

Ans: C In qualitative reports, researchers often organize findings according to the major themes, processes, or categories that were identified in the data. The results section of qualitative reports sometimes has several subsections, the headings of which correspond to the researcher's labels for the themes. The introduction to a research article acquaints readers with the research problem and its context. The text presents a narrative summary of key findings, often accompanied by more detailed tables.

Ans: C Validity is the soundness of the study the quality of evidence about the relationship between the independent variable and the dependent variable. The accuracy and consistency of information that is obtained from a study is its reliability. Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretation. Trustworthiness in qualitative research encompasses several difference dimensions, including credibility, dependability, confirmability, transferability, and authenticity.

In a research report, limitations of the study are normally discussed in which section? A) Introduction B) Method section C) Results section D) Discussion section

Ans: D A discussion section that presents the researcher's grasp of study limitations demonstrates to readers that the authors were aware of the limitations and probably took them into account in interpreting the findings.

Which of the following is an aspect of trustworthiness used in evaluating the strength of evidence in a qualitative study? A) Triangulation B) Reflexivity C) Reliability D) Credibility

Ans: D Credibility is achieved to the extent that the methods engender confidence in the truth of the data and in the researchers' interpretations. Triangulation, the use of multiple sources or referents to draw conclusions about what constitutes the truth, is one approach to enhancing credibility. Reliability (a key challenge in quantitative research) refers to the accuracy and consistency of information obtained in a study. Reflexivity, the process of reflecting critically on the self and of scrutinizing personal values that could affect data collection and interpretation, is an important tool in qualitative research.

Ans: D In the discussion, the researcher presents conclusions about the meaning and implications of the findings, i.e., what the results mean, why things turned out the way they did, how the findings fit with other evidence, and how the results can be used in practice. The method section describes the methods used to answer the research questions including the sampling plan. The introduction to a research article acquaints readers with the research problem and its context. The results section presents the findings that were obtained by analyzing the study data. The text presents a narrative summary of key findings, often accompanied by more detailed tables.

A nurse researcher compared men's and women's level of stress following cardiac surgery and made sure that both groups were comparable with regard to length of stay in hospital. Length of stay in hospital is which of the following? A) Independent variable B) Dependent variable C) Mediating variable D) Confounding variable

Ans: D Researchers seek to control confounding (or extraneous) variablesóvariables that are extraneous to the purpose of a specific study but that might contaminate the results because they may be the actual cause or influence on the dependent variable. In this case, length of stay in the hospital may be the actual cause or at least one cause of the level of stress, instead of the cardiac surgery. The dependent variable is the behavior, characteristic, or outcome the researcher is interested in explaining, predicting, or affecting, which in this case is level of stress. The independent variable is the presumed cause of or influence on the dependent variable, which is cardiac surgery, in this case. The independent variable corresponds to the ìIî and the ìCî components in the PICO scheme. A mediating variable is a factor through which another factor has an effect on a dependent variable. In this case, for example, the effect of cardiac surgery on stress is mediated by length of stay, making length of stay the mediating factor.

The statement "the results of this study are statistically significant" means which of the following regarding the findings? A) Passed a Chi test B) Are clinically important C) Are the strength of the study D) Are probably true and replicable

Ans: D The statement ìthe results of this study are statistically significantî means that the findings are probably true and replicable. Findings that are statistically significant have a high probability of being ìreal.î Statistically significant does not mean that the study findings passed a Chi test, are clinically important, or are the strength of the study.

The use of multiple data collection methods to draw conclusions about the area being studied is called which of the following? A) Bias B) Statistical test C) Research control D) Triangulation

Ans: D Triangulation is the use of multiple sources or referents to draw conclusions about what constitutes the truth. A bias is an influence that results in an error in an inference or estimate. Researchers use statistical tests to test their hypotheses and assess the probability that the results are accurate. Research control usually involves holding constant influences on the outcome variable so that the true relationship between the independent and outcome variables can be understood.

When a research report undergoes a "blind" review for a journal, it means which of the following? A) The journal editors do not know who submitted the report. B) The authors of the report do not know who the editor of the journal is. C) The report is published without indicating the authors' names. D) The reviewers making recommendations about publication are not told who the authors are.

Ans: D Usually, manuscripts are reviewed by two or more peer reviewers (other researchers) who make recommendations about whether to accept or reject the manuscript, or to suggest revisions. Reviews are usually ìblindîóreviewers are not told researchers' names, and authors are not told reviewers' names. As a result of peer review, consumers have some assurance that journal articles have been critiqued by other nurse researchers.
