Course Goals, Learning Objectives, and relationship to Program Outcomes 2.1. Goals: The overall goal of BME 223 is to introduce statistical methods for making inferences in engineering, biology and medicine. You will learn a number of essential statistical techniques for use in analyzing data from different types of experiments and you will apply them to data from biological experiments and clinical studies. In the course you will learn about: descriptive statistics; elementary probability; discrete and continuous random variables and their distributions; hypothesis testing involving continuous and categorical (nominal and ordinal) variables, two and more treatments; linear regression; analysis of survival data; design of clinical trials. 2.2 Learning objectives and relationship to program outcomes: After successfully completing this course, you should be able to: explain and apply descriptive statistics (including measures of central tendency and dispersion) to summarize experiment data (BME Program Outcomes 1 and 3 - see last page); know what a random variable is (discrete and continuous), some common probability distributions and how to calculate expected values (Outcomes 1 and 3) explain and implement methods for testing differences between treatment groups when the measurements are continuous, including: F-test; unpaired and paired t-test; analysis of variance; repeated measures ANOVA (Outcomes 1 and 3) 1 explain and implement methods for testing differences between treatment groups when the measurements are categorical, including: Chi square analysis; Mann Whitney test; KruskalWallis statistic; Wilcoxin signed-rank test; McNemar’s test (Outcomes 1 and 3). describe and implement methods for assessing the relation between two variables using linear regression analysis (Outcomes 1 and 3); explain and implement analysis of survival data and tests for evaluating the effects of treatments using survival data (Outcomes 1 and 9); select and implement the appropriate statistical procedure needed for a particular experiment paradigm, data collected and question to be answered (Outcomes 1 and 9); design a clinical trial to test whether a treatment produces an effect (type of experiment, number of subjects, etc.), considering ethical issues of human trials (Outcomes 2 and 4); use the GLANTZ software to implement and perform the statistical tests presented in class using biomedical (laboratory and clinical trial) data sets (Outcomes 1, 3 and 9); prepare written reports that document solutions to homework projects and present simulations results and analyses (Outcome 5); supplement through independent study of reference readings, the statistical concepts presented in class and their biomedical applications (Outcome 7). 3. Course Plan The course plan detailed below reflects the course goals and the learning objectives. The lectures emphasize different statistical methods, while the homework projects require an understanding of the appropriate statistical procedure required as well as the procedure to perform the particular test, given the experiment data and question posed. The class material is covered in the following order: Aug. 26: Sept. 2: Sept. 9: Sept. 16: Sept. 23: Sept. 30: Oct. 7: Oct. 14: Oct. 21: Oct. 28: Nov. 4: Nov. 11: Nov. 18: Nov. 25: Dec. 2: Dec. 9: Introduction; Descriptive Statistics Basic Probability; Random Variables (HW#1 assigned) Hypothesis Testing – Differences Between Groups Hypothesis Testing – Special Case of Two Groups Methods for Proportions & Nominal Variables (HW#1 due, HW#2 assigned) Methods for Proportions & Nominal Variables Confidence Intervals (HW#2 due) Midterm Exam Linear Regression (HW#3 assigned) Linear Regression Analysis of Variance for Multiple Treatments Nonparamteric Methods (HW#3 due, HW#4 assigned) Survival Analysis Thanksgiving Vacation Ethical Issues in Clinical Trail Design (HW#4 due) Final Exam (2:00 - 3:30. ZHS 252) 2 4. Textbooks: Required: Primer of Biostatistics (with software). Stanton A. Glantz, McGraw Hill, 5th or 6th edition, 2002/2005. 5. Grading: Midterm Exam Final Exam Homework (4) 40% 40% 20% All homework assignments are to be turned in at the beginning of class on the day they are due. For every day (or portion of a day) an assignment is late, 25% will be subtracted from its maximum point total. You may discuss strategies for solving the homework with your classmates; however, outright plagiarism of other’s work will be treated following the University’s guidelines for violations of academic integrity. 6. Web Page: This course uses the USC TOTALe system (aka Blackboard) and can be accessed via http://totale.usc.edu. To get started with TOTALe, point your browser to http://totale.usc.edu and then select BME 423. Be sure to CHANGE YOUR EMAIL to the one you use most frequently as we will send out e-mail messages during the semester using your e-mail address that is associated with TOTALe. 7. Special Accommodations: Any student requesting academic accommodations based on a disability is required to register with Disability Services and Programs (DSP) each semester. A letter of verification for approved accommodations can be obtained from DSP. Please be sure the letter is delivered to me (or to TA) as early in the semester as possible. DSP is located in STU 301 and is open 8:30 a.m. – 5:00 p.m., Monday through Friday. The phone number for DSP is (213) 740-0776. 3 BME Program Outcomes 1.
