Use of Regression Analysis in Clinical Practice

Order Instructions

Regression analysis provides the researcher with an opportunity to predict and explore future outcomes. Whether it is to determine prevention methods, promote opportunities for learning, or propose new treatments, looking towards the future can have a significant impact on patient care and sustained positive patient outcomes.


This week, you explore regression analysis, paying particular attention to linear regression. Linear regression is used to “estimate the value of a dependent variable based on the value of an independent variable” (Gray & Grove, 2020). In your Discussion, you will apply your understanding of this statistical technique as it concerns use in a research study.


For this Discussion, you will select an article on a study to examine the strengths and weaknesses in the use of linear regression. Consider how you might remedy the weaknesses associated with the application of linear regression and reflect on how the findings of the study that you selected might contribute to various areas of your practice.


o Prepare:

• Review the articles in this week’s Learning Resources and evaluate their use of linear regression. Select one article that interests you to examine more closely in this Discussion.

• Critically analyze the article that you selected and consider the strengths and weaknesses described.

• Reflect on potential remedies to address these weaknesses, and how the findings from this study may contribute to evidence-based practice, the field of nursing, or society in general.




Post a brief description of the article that you selected, providing its correct APA citation. Critically analyze the article by addressing the following questions:


• What are the goals and purposes of the research study that the article describes?

• How is linear or logistic regression used in the study? What are the results of its use?

• What other quantitative and statistical methods could be used to address the research issue discussed in the article?

• What are the strengths and weaknesses of the study?


Then, explain potential remedies to address the weaknesses that you identified for the research article that you selected. Analyze the importance of this study to evidence-based practice, the nursing profession, or society. Be specific and provide examples.
