SCHOOL OF NURSING MISSION STATEMENT: Consistent with the mission and purpose of the University, the School of Nursing is a Christian community of discipleship, scholarship, and practice. Its purpose is to advance the work of God in the world through nursing education, collaborative projects, and Church and community service that encourages those affiliated with the School of Nursing (whether faculty, staff, student, graduate, or colleague) to grow in faith and in the exercise of their gifts for service to God and humanity. COURSE DESCRIPTION: This course presents common nonparametric and parametric statistical techniques used in health care research. Assumptions of the techniques will be addressed. Specifically, the course will emphasize t-tests, ANOVA, ANCOVA, RANCOVA, correlation, odds ratio, regression, and power analysis. The course will provide the student experience in using SPSS for entering and analyzing data. Reporting results of the analyses will also be incorporated. Making appropriate decisions regarding which statistical techniques to use will be stressed. Critique of statistical analyses of published health care research will also be emphasized. Note: Each student will use the computer lab each week to become familiar with SPSS in relation to entering data, using statistical techniques, producing charts/graphs, and interpreting output. Students will use databases provided in textbook for analyzes of data using the various statistical techniques. Students will also have the opportunity to use other databases from current nursing studies. STUDENT OUTCOMES 1. Determine which statistical techniques are appropriate for selected research designs 2. Explain the assumptions of selected statistical techniques 3. Analyze data using the appropriate statistical techniques 4. Write the results of statistical analyses 5. Evaluate the appropriateness of statistical analyses reported in research publications 6. Perform power analyses for selected studies

If the student earns one course grade below B-, that one course may be repeated one time for a higher grade. The student is automatically placed on probation and is expected to repeat the course for a higher grade the next time the course is offered or within two semesters, whichever is sooner. Ph.D. students may have not more than one C in any course in the program. This course must be repeated at its next regularly scheduled offering, and passed with a grade of B or better. A second B- grade in this or any subsequent course will result in dismissal from the program even if the GPA is above the minimum. Note: C-, D, & F are unacceptable grades in the PhD program Course Policies Attendance to class is mandatory. Students should contact faculty member if unable to attend. No late assignments will be accepted; however, in the event of unusual circumstances, the student must inform
5 the instructor immediately the reason for not completing the assignment. A new due date will be negotiated with the student depending on the circumstances. Available Support Services for Students with Disabilities Students in this course who have a disability that might prevent them from fully demonstrating their abilities should contact an advisor in the Learning Enrichment Center (ext. 3849) as soon as possible to initiate disability verification and discuss accommodations that may be necessary to ensure full participation in the successful completion of course requirements. Written documentation of the disability, along with a request for accommodation, should be presented to the course instructor at the beginning of the course, or as soon as the disability has been diagnosed. HIPAA Compliance In order to avoid violations of HIPAA, you must not collect in your notes or include in any reports (e.g., patient care plans) any information that would permit a third party to identify a specific patient. Such information includes, but is not limited to, a patient s name, address, social security number, or the name of the hospital or clinic where you observed the patient. For example, the diagnosis alone or situation may be such as to permit others to identify the patient. If other information permits a third party to identify the patient, you should consult with your faculty member regarding the appropriate way to comply with your course assignment prior to preparing a report about that patient.
