Patient BMI and Cholesterol Level at Screening - Nursing Assignment Help

Assignment Task

Question 1 (Difference Between Means):
a) Is there a significant difference in Cholesterol change from screening to follow up for patients who have taken Drug A compared to Drug B for patients aged 22-25? (Create a new data column for the change in cholesterol, for example CHOL3-CHOL.)
Question 2 (Chi-Square):
a) Is there an association between patient BMI and cholesterol level at screening? Consider overweight, normal and underweight categories for BMI
Question 3 (Regression):
Is there a relationship between weight and LDL level at screening for male patients aged 22-25?
Report 2:
Inferential statistics and completed report (see “Statistical Inference” section below)
Apply statistical methods used in class to answer the project questions.
Produce a formal/professional report including descriptive statistics. Appendix ‘B’ provides some report guidelines.
Description of the Data and Problem:
You are a group of statisticians who provide consulting services to small biotechnology and life science companies. A client has performed an exploratory pilot study to investigate the relationships between two cholesterol lowering drugs, lifestyle information, and blood lipid levels. Data were collected from each patient at a screening visit and at a follow-up visit three months later. At the screening visit, demographics, lifestyle information, and blood lipid readings were collected. At the follow-up visit, weight and blood lipid readings were collected as well as information as to whether or not the patient experienced stomach pain while taking the cholesterol lowering drug.
Assignment Details:
Your group will select three questions of interest from the instructor's list of assigned questions and then define an appropriate subset of the data to investigate these questions. Three statistical analyses will determine the questions you analyze, and they are:
(1) A Hypothesis Test and Confidence Interval for Two Means (Chapter 11)(2) A Hypothesis Test using the Chi-Square Distribution (Chapter 12)(3) Analysis of the Relationship between Two Continuous Variables (Chapters 4 & 14)
Your report will contain the following sections:
(I) Introduction – Provide an overview of the project, the questions that were studied (and why you chose these particular questions), and analyses that were performed. Define the data that were used, details about any transformations performed on the data, and discussion on existing outliers.
(II) Statistical Analysis of Each of the Three Questions – Each question being analyzed should include descriptive and inferential data. Details of each are as follows:
· Descriptive Statistics & Graphical Displays (Chapters 2 and 3) – Provide some meaningful descriptive statistics about the data such as mean, median, standard deviation, range, quartiles, IQR, fences, outliers, etc. and put this data in a table. Include charts that will best display the data – usually bar graphs, histograms, regression plots, are effective, but other types of charts
presented in the textbook may also be helpful. Make sure your tables and charts are appropriately labeled and clearly discussed in your text. Large data tables showing transformations, if necessary, should be placed in an appendix so as not to interfere with the flow of the report. Refer to Appendix 'A' for examples of what is expected.
· Statistical Inference – For each of the analyses state the question of interest which was investigated, analysis method that was used, mathematical/statistical details, your conclusion,and an interpretations statement. Each of these should be presented in the same way as theexamples in the book showing the steps – hypotheses, critical values, formulas, test statistics, decisions/conclusions, and summary interpretation statement. It is necessary to showintermittent calculations, and show enough of your work so that numbers can be evaluated. Present both the “classical” and “p-value” approaches and provide an interpretation statement for the
confidence intervals. The p-values can be obtained using the tables (and estimating if necessary) or by using a calculator or software.
The question involving regression should include a scatter plot of the data and the least-squares regression line on a single graph, calculation of the correlation coefficient, and the equation of the least-squares regression line. Comment on the relationship that appears to exist based on the results of the scatter plot and correlation coefficient and coefficient of determination. Interpret the slope and y-intercept of the least-squares regression line. Test whether a linear relationship exists between the explanatory and response variables and calculate a confidence interval for the slope of the regression line. Remember to provide an interpretation statement for your tests.
(III) Conclusion – Summary of your analyses and recommendations for further study.
