Objectives: At the end of this course, the students are expected to:
1. Apply statistical and epidemiologic knowledge to design a research proposal
2. Use SPSS for data management, data analysis and interpretation
Materials: A statistical program, called SPSS will be used for all statistical purposes. A scientific calculator will compliment the data analysis.
Cellular phone/pager: Please turn them off in the class.
Grading policy:

Your final grade will be determined by your performance in the following areas:
Tests on data analysis
and interpretation (4) 40 points
Research proposal (10 pages
excluding references) 20 points
Questionnaire development 10 points
Data management: creating variables,
data entry, data editing 10 points
IRB certification 10 points
Class
participation 10
points
Total: 100 points
Exams:
Tests: Mainly interpretation of the statistical analysis and short answers. You may need a calculator. There will be no makeup exams given. If you miss an exam for an inexcusable reason, you will receive no credits for that exam. If you have prior knowledge of a schedule conflict regarding an exam, please make arrangements to take it early with valid documents.
Assignments: Deadlines for the assignments will be honored. If you turn in an assignment in late without an excusable reason, 2 points will be deducted for each day being late.
Research Proposal: Your proposal need to be approved by the instructor. It includes the following sections:
1. Introduction: Public health importance of your topic. Previous information related to this topic. Any controversies, unsolved questions, or future directions. Aim of the project. Hypothesis if any. Use appropriate references in the text.
2. Methods and Materials: Population, site of the study, and study design. Selection criteria. Exclusion criteria. Methods of interventions (if any). Clinical/laboratory/community based procedures. Monitoring. Variable of interest. Any confounders. Sample size estimation. Statistical methods.
3. Data analysis plan: Show dummy tables and figures and rationale for the analysis.
4. Reference (in APA or Vancouver style).
Questionnaire Development: You will develop a questionnaire based on your research questions. The minimum length of variables is 20.
IRB certification:
Complete a computer-based training
module offered by NIH. The web site is: http://ohsr.od.nih.gov Click on
"Computer-Based Training" then "IRB Member" (although you
are not a member) and register. The module takes about an hour to
complete. You may exit the module at any time and reenter at your
convenience. Upon completion you may print out a "Certificate of
Completion". Please bring me a copy of your certificate, you get 10
points.
