Week 7: Quantitative Analysis and Interpretation: Regression
How might you predict future events in your practice? Why is it important, as a future DNP-prepared nurse, to consider such future events?
For a DNP-prepared nurse, future predictions might lead to better patient outcomes and care. Therefore, analyzing factors to predict or evaluate can assist in transforming nursing practice or healthcare delivery. The “statistical procedure most commonly used for prediction is regression analysis” (Gray & Grove, 2020).
This week, you will examine the application of linear regression. You will analyze the strengths and weaknesses of the findings in a research study determined with linear regression, as well as explore alternatives to strengthen the aims of the study. You will also begin work on an Article Critique Assignment. While this Assignment is not due until Week 10, you are encouraged to begin this Assignment this week.

Discussion: Use of Regression Analysis in Clinical Practice
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.

To 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.
By Day 3 of Week 7
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.
By Day 6 of Week 7
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.
Note: For this Discussion, you are required to complete your initial post before you will be able to view and respond to your colleagues’ postings. Begin by clicking on the “Post to Discussion Question” link and then select “Create Thread” to complete your initial post. Remember, once you click on Submit, you cannot delete or edit your own posts, and you cannot post anonymously. Please check your post carefully before clicking on Submit!
