NUR 3405 Quiz #3 Coursepoint Questions, 100% Accurate. 2022/2023. A nurse researcher is deciding whether or not to utilize a mixed methods (MM) research design for an evidence-based practice p... roject. Which statements about an MM research design are true? (Select all that apply.) - ✔✔MM research can be used to generate and test a hypothesis., MM research can be used to help to confirm a theory. A researcher studied the impact that stress had on students in a nursing program. One hundred bachelor of science in nursing students completed the Perceived Stress Scale. Twenty students then volunteered to discuss the issue of stress as part of a focus group. The data sets were analyzed separately, and then the results were combined and interpreted. Which is the correct term for the design used for this MM research? - ✔✔Convergent parallel design A nurse researcher is reading an MM-designed research article. The nurse researcher would know which notation identifies a study as MM with equal qualitative and quantitative sections? - ✔✔QUAL/QUAN A nurse limits researching evidence-based articles to quantitative studies only. What does this approach do? - ✔✔Prevents a holistic view of the issue. Researchers should offer an interpretation of their findings. Which statements concerning the interpretation section of a study are correct? (Select all that apply.) - ✔✔Implications for nursing should be clearly stated., Limitations should be clearly stated. To be a good interpreter of research results, it is a good idea to start with a null hypothesis. A null hypothesis indicates: - ✔✔There are possible errors in the design of the study. A researcher reports that the results of a study are statistically significant. The nurse reading the report correctly interprets this statement as indicating: - ✔✔The results are not likely due to chance. A study yielded nonsignificant results. The nurse reading this study correctly interprets this as - ✔✔The null hypothesis may be correct. A researcher is studying self-efficacy in a population of mothers with newborn babies. Due to the length of time of data collection, data is collected from mothers anywhere from 5 days after giving birth to 4 weeks after giving birth. What threat to internal validity does this situation represent? - ✔✔Maturation A quantitative instrument can be reliable without being valid. - ✔✔TRUE Which of the following measures of validity concerns whether an instrument has the appropriate sample of items for the construct being measured? - ✔✔Content validity External validity refers to the ability to generalize results from a research study sample to a larger population. - ✔✔TRUE Identify common threats to internal validity. (Select all that apply) - ✔✔Selection, History, Mortality, Maturation Internal validity measures the research: - ✔✔results for accuracy. What important aspects of validity should an instrument or scale examine? (Select all that apply.) - ✔✔Construct validity, Criterion-related validity, Content validity Identify common threats to external validity. (Select all that apply.) - ✔✔Reactivity, Novelty, Experimenter External validity is important to evidence-based practice (EBP) because it allows researchers to: - ✔✔generalize evidence from controlled settings to real-world practice settings. A nurse researcher has developed and tested a new instrument. Which of the following coefficient alpha results indicates that the researcher's instrument is highly reliable? - ✔✔0.82 Reliability is the consistency in which an instrument measures an attribute. Which of the following are aspects of reliability that are important to researchers? (Select all that apply.) - ✔✔Test-retest, Internal consistency, Stability Which measurement is used when determining the internal consistency of a new instrument? - ✔✔Cronbach's alpha [Show More]
