    Request Description

    Hello,

    I need professional assistance completing Chapter 4 (Data Analysis and Results) and Chapter 5 (Discussion, Conclusions, and Recommendations) for my doctoral dissertation.

    I have attached several important files that must be carefully reviewed before starting the work.

    Attached Files

    1. Chapter 13 file
      This file contains the background of the study, research problem, conceptual framework, variables, hypotheses, and research methodology.all the first three chapter of dissertaion in this file
    2. Excel dataset file
      This file contains the dataset that will be used for the statistical analysis.
    3. Word file with data source links
      This file contains the original data source links used to collect the dataset.
    4. Instruction file for Chapter 4 and Chapter 5
      This file contains detailed instructions that must be followed when performing the statistical analysis and writing Chapter 4 and Chapter 5.

    Important:
    The instruction file must be followed exactly when conducting the statistical analysis and preparing the chapters.

    What I Need From You

  • Carefully review Chapter 13 to understand the research design and study variables.
    Carefully review the instruction file and follow it step-by-step.
    Review the Excel dataset and confirm that the data is correct and ready for statistical analysis.
    If any corrections are needed in the dataset, fix them properly before conducting the analysis.
    Use the data source links provided to verify the dataset if necessary.
    Perform the statistical analysis correctly and professionally according to the instructions.
    Ensure that the statistical tests, tables, and results are consistent with the methodology described in Chapter 3.

    Step 2: First Draft

    • Commit a good-faith effort to address each item in the Prompt section below.
    • Please be sure to number your responses and include “white space” between problem numbers. This improves the readability and flow of your work. I cannot give feedback and grade jumbled work.
    • Use either of the following options to submit your work.
      OPTION 1: You can submit a text-entry assignment (i.e. typing your answers in Canvas). To learn how to submit a text-entry assignment, use these (opens in a new tab).
      OPTION 2: You can upload your paper-and-pencil work (or the digital equivalent). To learn how to upload your paper-and-pencil work, use these (opens in a new tab). WARNING – some file types may not be visible on my end. So to learn which files you can upload, be sure to use the directions link I provided for this option.
    • Not ready to submit a good-faith effort yet?

    Step 3: Optional Final Draft

    • After you submit your good-faith attempt to fully respond to the questions in the Prompt section below, advance to the ANSWER(S) page.
    • You can use the ANSWER(S) page to correct your work and resubmit this assignment any time before I begin grading the problems. However, to earn full credit, you are not required to submit a final draft for this assignment. But if you do submit a final draft, I will only grade it if you submitted a good-faith effort on your first draft.
    • Warning – I will only grade your most recent submission. So if you choose to submit a final draft, please do not leave anything out, and please do not direct me to read an earlier submission. To maximize your score, your most recent submission (at the time I begin grading) must be complete.

    Context

    Clinical depression is a recurrent illness requiring treatment and often hospitalization. Nearly 50% of people who have an episode of major depression will have a recurrence within 2-3 years. Being able to prevent the recurrence of depression in people who are at risk for the disease would go a long way to alleviate the pain and suffering of patients.

    During the 1980s the federal government, through the National Institutes of Health (NIH), sponsored a large clinical trial to evaluate two drugs for depression. There were 3 treatment groups. Patients received either Imipramine (Imip), Lithium (Li), or a Placebo (Pl). Researchers randomly assigned patients to one of the 3 treatment groups and followed them for 2-4 years to track any recurrences of depression.
    (Prien et al., Archives of General Psychiatry, 1984).

    Variables

    • Hospt: Which hospital the patient was from: Labeled 1, 2, 3, 5 or 6
    • Treat: 0=Lithium; 1=Imipramine; 2=Placebo
    • Outcome: 0=Success 1=Failure (recurrence of depression)
    • Time: Number of weeks until a recurrence (if outcome=1) or until study ended (if outcome=0)
    • AcuteT: How long the patient was depressed before the start of the current study, measured in days
    • Age: Age in years
    • Gender: 1=Female 2=Male

    Data

    • If you have not already done so, open the depression data set in the Stats at Cuyamaca College group on StatCrunch ( – opens in a new tab).

    Prompt

    We will analyze the data to answer the second research question: Which of the drugs (if either) delayed the recurrence of depression longer relative to the placebo?

    In the previous lab-preparation activity, we identified Treat as the explanatory variable and Time as the response variable. We also determined that we will analyze the data using side-by-side boxplots and descriptive statistics (i.e. 5-number summaries since the graphs are boxplots).

    1. Make graphs and tables:
      1. Use StatCrunch to produce side-by-side boxplots. ()
        Embed your graphs into the textbox, and be sure to include the Alt Text. To recall how to embed a picture into a textbox, see the StatCrunch directions below.
      2. Use StatCrunch to produce the descriptive statistics (a single table containing the 5-number summaries for each comparison group). ()
        Copy and paste the StatCrunch output table into the textbox.
    2. Analyze the data: Compare the distributions for the treatment groups as demonstrated in Unit 2. For example, compare medians and intervals of typical values. Describe the shape and any outliers. Be sure to write your comparisons so the reader can understand the context of the numbers. For example, don’t just say the median is 30; instead, say something like this: on average patients taking the placebo relapsed in 30 days (Q2=30 days).
    3. Draw a conclusion: What can we conclude from your analysis? Did one drug successfully delay a relapse of depression better than the others? What evidence supports your conclusion?
    4. Summarize your conclusions in response to both research questions: In this lab, you compared three treatments (two drugs and the placebo) using two different variables. In Part 1 you compared whether or not a relapse into depression occurred for each of the two drugs and the placebo. In Part 2 you compared the length of time until the next relapse for the two drugs and the placebo. What can you conclude in light of both analyses? Is one treatment better than the other? How does the data support your conclusion?
