How to Research and Prepare for NRS 394 Correlation and Regression SOLVED

Whether one passes or fails an academic assignment such as the Chamberlain University NRS 394 Correlation and Regression SOLVED depends on the preparation done beforehand. The first thing to do once you receive an assignment is to quickly skim through the requirements. Once that is done, start going through the instructions one by one to clearly understand what the instructor wants. The most important thing here is to understand the required format—whether it is APA, MLA, Chicago, etc.

After understanding the requirements of the paper, the next phase is to gather relevant materials. The first place to start the research process is the weekly resources. Go through the resources provided in the instructions to determine which ones fit the assignment. After reviewing the provided resources, use the university library to search for additional resources. After gathering sufficient and necessary resources, you are now ready to start drafting your paper.

How to Write the Introduction for NRS 394 Correlation and Regression SOLVED

The introduction for the Chamberlain University NRS 394 Correlation and Regression SOLVED is where you tell the instructor what your paper will encompass. In three to four statements, highlight the important points that will form the basis of your paper. Here, you can include statistics to show the importance of the topic you will be discussing. At the end of the introduction, write a clear purpose statement outlining what exactly will be contained in the paper. This statement will start with “The purpose of this paper…” and then proceed to outline the various sections of the instructions.

How to Write the Body for NRS 394 Correlation and Regression SOLVED

After the introduction, move into the main part of the NRS 394 Correlation and Regression SOLVED assignment, which is the body. Given that the paper you will be writing is not experimental, the way you organize the headings and subheadings of your paper is critically important. In some cases, you might have to use more subheadings to properly organize the assignment. The organization will depend on the rubric provided. Carefully examine the rubric, as it will contain all the detailed requirements of the assignment. Sometimes, the rubric will have information that the normal instructions lack.

Another important factor to consider at this point is how to do citations. In-text citations are fundamental as they support the arguments and points you make in the paper. At this point, the resources gathered at the beginning will come in handy. Integrating the ideas of the authors with your own will ensure that you produce a comprehensive paper. Also, follow the given citation format. In most cases, APA 7 is the preferred format for nursing assignments.

How to Write the Conclusion for NRS 394 Correlation and Regression SOLVED

After completing the main sections, write the conclusion of your paper. The conclusion is a summary of the main points you made in your paper. However, you need to rewrite the points and not simply copy and paste them. By restating the points from each subheading, you will provide a nuanced overview of the assignment to the reader.

How to Format the References List for NRS 394 Correlation and Regression SOLVED

The very last part of your paper involves listing the sources used in your paper. These sources should be listed in alphabetical order and double-spaced. Additionally, use a hanging indent for each source that appears in this list. Lastly, only the sources cited within the body of the paper should appear here.

Sample Answer for NRS 394 Correlation and Regression SOLVED

Congrats to all for surviving this course! Wasn’t this like trying to lean a new language in 8 weeks?

I found an excellent article in our library that compared different regression models for the best approach to predicting BMI: “Factors associated with overweight: are the conclusions influenced by choice of the regression method?” (Juvanhol et al., 2016). The bottom line was the authors recommend using a combination of different approaches, as these furnish complementary information to the multifactorial predictors of obesity. The article was a little over my head as it discussed gamma regression, which I couldn’t find in our textbook, and quantiles, which also is not in our text but seems a lot like quartiles. But thanks to this course, I was able to understand more of this article than I would have before this course.

In this article, BMI distribution percentiles is on the x-axis of the following charts. The along the y-axis were the values of the estimated coefficients for age, physical inactivity, years of night-shift work, BMI at age 20, domestic overload (cleaning/cooking/laundry factored by number of residents at home) and self-rated health. According to Juvanhol et al., (2016), these were the explanatory variables. This is still a little confusing to me, as Holmes et al. (2018) stated that a multivariate model or system is where more than one independent variable is used to predict an outcome, and there can only be one dependent variable, but unlimited independent variables. So why did the authors refer to age, etc., as explanatory variables, which would made them independent variables, but not put them on the x-axis?

Anyway, the independent variables are along the y-axis, and are shown in units of the values of the coefficients estimated. Coefficients provide an estimate of the impact of a unit change in the independent variable on the dependent variable (Holmes et al., 2018). The coefficient we use in a linear regression is the slope, or the rise over the run. However, this week we learned about another kind of coefficient, the coefficient of determination which is the explained variation over the total variation (Chamberlain University, 2021). I am not sure which coefficient the authors are referring to in the article.

The grey shaded areas around each line show the 95% confidence interval for the quantile estimates. It is interesting to note the narrowness of the spread of the confidence interval around the line in the “Age” graph and the “BMI at age 20” graphs in comparison to the other four graphs even though they are all at the 95% confidence level. We all know now that a narrow confidence interval is preferred over a wide one (Holmes et al., 2018).

To answer the final question, which statistic would show the value of that regression line in understanding BMI, I’d give more weight (pardon the pun) to the statistics of “Age” and “BMI at age 20” due to the narrowness of the confidence intervals, but also interesting is the way the “Years worked at night” regression line jumps at about the 80th quantile showing a suddenly stronger association in the upper quantiles. That would be an interesting area to investigate.

Sample Answer 2 for NRS 394 Correlation and Regression SOLVED

Correlation and regression analysis are parametric, inferential statistics are often applied in the processes of data analysis. Correlation has helpful in the determination of the relationship that exist between two continuous variables in the dataset. For effective computation of the correlation coefficient, there is always the need for the data to be normally distributed. In other words, there is always the assumption of normality. Correlation can be computed between independent and dependent variable, both the variables need to be normally distributed (Kasuya, 2019). While correlation is only applied in the determination of the relationship that exist between one independent and one dependent variable, regression analysis can be applied in the determination of the relationship that exist between one dependent variable and one or more independent variables. In other words, regression analysis is important in the analysis of more variables in a given dataset.

When a regression analysis was to be completed on the body mass index (BMI), there are several independent variables that could be included in the processes of analysis. In other words, for the regression analysis on the body mass index, the independent variable can be activity level or frequency in undertaking physical activities. The activity level can be measured in terms of the amount of time taken while undertaking physical activities (Zhang et. Al., 2019). From the theoretical perspectives and from the previous research processes, it has been established that continuous physical exercise can lead to the reduction in weight. In other words, physical activities have direct impacts on body weight. For effective outcomes of the regression analysis, there is the need for the independent variables to have a normal distribution, also, they need to be continuous variables.

Another independent variable that may relate to the Body Mass Index is the amount of fatty food intake. In most cases, increased intake of fatty foods is one of the major contributors to increase in body mass index. Individuals who consume high amount of fatty foods often tend to experience increase in body weight. As a result, their body mass indices are likely to increase. While using amount of fatty foods intake as an independent variable, there is a need ensure that it is continuous and normally distributed. Finally, height may be considered as one of the independent variables in the regression analysis whereby BMI has been used as dependent variable. The determination of body mass index often involve the incorporation of the height of an individual. The body mass index is determined through dividing the weight of an individual with the square if the height. Therefore, height is an important determinant of the body mass index.

From the regression analysis, there is ANOVA outcomes that can be applied in the determination of whether the model is fit. From the ANOVA table, the significant values can always show if there is the relationship between the dependent and independent variables. The significant values can be tested against the alpha value at 0.05. Also, the mean square as well as the F-values obtained can be used to determine the values of body mass index. Also, the unstandardized coefficients can be applied in the determination of the correlation coefficient in the process of determining the relationship between the dependent and independent variables in the process of analysis.

If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
