Assignment 2: Interpreting Data Written Assignment
Instructions: Answer each problem and present your report as though it were sections from a manuscript in a peer-reviewed journal (i.e., using full sentences and statistical language).
1) Under the heading “Purpose” state the purpose of the research question and the hypotheses (i.e., what you are looking for).
2) Under the heading “Statistical Methods”, describe the statistical methods you applied to answer the research question (i.e., what you did). This should include a description of the descriptive statistics you conducted, what inferential statistical test was selected (and why), the significance level, and statistical software used
3) Under the heading “Results” present your findings (i.e., what you found) and 1 figure. Include at least one measure of central tendency and variability. An assumption check (describe what you did and what you found, as needed), check for potential outliers, and present the findings of your inferential test (i.e., your critical value and p value), as appropriate. You may use tables in your results section if it helps your explanation. If you find you find outliers, you must elaborate on what you did with them (i.e., whether you removed or kept them), in the results section.
4) Finally, under the heading “Interpretation” provide a brief interpretation of your results, including a description of the figure. Discuss whether you reject or fail to reject the null hypothesis and what that means.
The answers to each problem should be approximately 1 - 1.5 pages, 12-point Times New Roman font; 1.5 spaced. Upload the report as a PDF.
Statistical output should be provided as a supporting document (not included in page count). SPSS output should be merged into one PDF and uploaded to the assignment dropbox. If using Excel to build graphs, please upload an Excel document to the assignment dropbox as well.
Refer to the assignment description & rubric for additional guidance on assignment expectations.
Problem #1
A clinician was interested in exploring functionality in patients following a stroke rehabilitation program. Participants were recruited through the rehabilitation unit at Providence Care Hospital. Functional status was evaluated at baseline (immediately following stroke), and 8 weeks later. Patients’ functional outcomes were rated on the following 5-point scale: 1 – poor, 2- fair, 3 – moderate, 4 -good, 5 – excellent. The clinician wants to know whether patients improved their functioning over the 8-week period.
Problem #2
A respiratory therapist reviewed patient records in four family practices for a period of 1 year. Newly diagnosed cases of asthma were noted, and whether the case was referred to hospital or not. The research team wants to know whether the practices differ in their proportions of hospital referrals for patients suffering from asthma.
Problem #3
A researcher was interested in studying the best way to teach suturing and casting to surgical residents. To study this, all incoming orthopaedic residents were divided into three groups: a standard training group scheduled to work in the emergency department (n=8), an instructor- led surgical skills boot camp group (n=8), and student-led surgical skills boot camp group (n=8). After 7 days of the intervention, suturing and casting skills were measured through a simulation-based exam. The researcher wants to know whether average exam scores differ between the three groups.
Problem 4
Recall from Module 01 you learned about Dr. Harold Shipman. A researcher is interested in reviewing the public inquiry data from Dr. Shipman’s case and exploring whether the age of his victims differed based on gender.
