Nurs 8201 Week 8 Discussion: Statistical Analysis In Nursing

Nurs 8201 Week 8 Discussion: Statistical Analysis In Nursing

The article chosen for this discussion is an article by Leigh et al.(2020). The goal and purpose of this article were to explore the predictors of emergency nurses’ protection motivation during the West African Ebola outbreak. This is an example of an article where nonparametric tests were used. For example, the Kruskal-Wallis H test was used in the analysis of the connection between the categorical independent variables like employment, licensure, education level, race, age groups, gender, and other variables related to protection motivation theory. The analysis gave important results. An example is the relationship between gender and psychological variables, which were analyzed.  From the Kruskal-Wallis H test, the self-efficacy χ² value was 11.74, indicating a significance at p<0.005. Male respondents also have a substantially higher self-efficacy as shown from post hoc Dunn-Bonferroni tests.

It is evident that this research did not use parametric methods such as ANOVA and t-test since they were inappropriate for the statistical analysis of the research study’s data. One of the reasons is that parametric tests assume that data usually follow normal distribution; as such, in case the data fails to follow such a trend (Grey & Grove, 2020), then parametric tests can lead to inaccurate results. A typical example from the paper is the case where the Kruskal-Wallis H test was used to explore the distribution of psychological variables in different age groups, as it doesn’t have to make an assumption that the data is normally distributed. ANOVA also assumes homogeneity of variance; hence, it may not be reliable when such an assumption does not hold (Orcan et al.,2020).

This study has various strengths. One of them is the sample size. The sample size was 388, which is sufficient, hence enhancing generalizability. There is also diversity in educational levels and age groups. The use of nonparametric tests such as Spearman rho correlation and Kruskal-Wallis H test in data analysis shows a robust approach (Juang, 2021). One weakness is that the cross-sectional design used limits the ability to explore the causal relationships between variables. It is also vulnerable to response bias as data collection relies on self-reported information. The findings and recommendations of this research study can contribute to EBP for nursing in that stakeholders can formulate tailored preparedness strategies by identifying factors that influence nurses’ perceptions.

WEEK 8 DISCUSSION: STATISTICAL ANALYSIS IN NURSING

 

“An essential component of nursing education is ensuring students develop the competencies in the use of empirical evidence in their clinical practice. The fundamental goal of statistics courses is to teach healthcare professionals the proper uses of statistical thinking to enable them to effectively evaluate the literature and integrate evidence into their practice” (Baghi & Kornides, 2014).

How are research methods used in nursing? What particular methods are used in your area of nursing practice? Over the last few weeks, you have been exploring these questions, and you will continue this exploration examining the specific tests and methods that may be used in your particular area of nursing practice. Why might different methods be used based on an area of practice? Why is it important for DNP-prepared nurses to be familiar with various research methods?

For this Discussion, reflect on the tests and methods utilized in research studies, presented over the last eight weeks of the course, to consider the approach, impact, and purpose of these in conducting nursing research. Using a selected article, consider the approach used and reflect on how that approach might fits within your area of nursing practice.

WEEK 8: LEARNING RESOURCES

Required Readings

 

TO PREPARE:

  • Review the articles presented in this week’s Learning Resources and analyze each study’s use of statistical and nonparametric tests.
  • Select an article to focus on for this Discussion.
  • Ask yourself: Which method is most commonly used in research studies that pertain to my area of nursing practice, and why this might be so?

BY DAY 3 OF WEEK 8

Post a critical analysis of the article that you selected by addressing the following:

  • What are the goals and purpose of the research study described by the article you selected?
  • How are nonparametric tests used in the research study? What are the results of their use? Be specific.
  • Why are parametric methods ( tests and ANOVA) inappropriate for the statistical analysis of the research study’s data? Be specific and provide examples.
  • What are the strengths and weaknesses of the research study (e.g., study design, sampling, and measurement)?
  • How could the findings and recommendations of the research study contribute to evidence-based practice for nursing?

BY DAY 6 OF WEEK 8

Read a selection of your colleagues’ responses and respond to at least two of your colleagues on two different days in one or more of the following ways:

  • Ask a probing question, substantiated with additional background information, evidence, or research.
  • Share an insight from having read your colleagues’ postings, synthesizing the information to provide new perspectives.
  • Offer and support an alternative perspective using readings from the classroom or from your own research in the Walden Library.
  • Validate an idea with your own experience and additional research.
  • Suggest an alternative perspective based on additional evidence drawn from readings or after synthesizing multiple postings.
  • Expand on your colleagues’ postings by providing additional insights or contrasting perspectives based on readings and evidence.
