The University of Texas at Tyler Executive Health Care Administration MPA Program SPRING 2013 COURSE NUMBER EHCA 5367 COURSE TITLE Biostatistics INSTRUCTOR John J. Lefante, Jr., Ph.D. INSTRUCTOR INFORMATION REQUIREDTEXT Email: [email protected] Phone: 504-988-7874 Biostatistics: A Foundation for Analysis in the Health Sciences, 9th ed., Wiley Publishing Co., 2009. AUTHOR: Wayne W. Daniel ISBN: 978-0-470-10582-5 COURSEDESCRIPTION This is an introductory course in applied biostatistics. It covers both graphical and numerical methods of describing data sets, an introduction to probability and probability distributions, estimation and hypothesis testing, and regression and correlation analysis. COURSE LEARNING OBJECTIVES The student will be able to: 1. Distinguish between categorical variables without order, categorical variables with order and continuous variables. 2. Select the appropriate graphic presentation for a set of data and generate the graph. 3. Construct frequency distributions. 4. Compute measures of central tendency (mean, median, and mode) and variability (variance, standard deviation). 5. Use the binomial and normal distributions to assess the probability and uncertainty of health outcomes. 6. Construct and interpret confidence intervals around means. 7. Differentiate between the research, null and alternative hypotheses. 8. Construct one and two-sided hypotheses. 9. Identify type I and type II errors, significance level, p value and power. 10. Determine the sample size needed for one- and two-sample tests on means. Page 1 of 3 11. 12. 13. 14. 15. 16. 17. Perform and interpret one-sample, two-sample, and paired t tests on means. Perform and interpret the normal theory two-sample test of proportions. Perform and interpret the F test to compare two variances. Perform and interpret chi square tests of independence. Compute the least squares estimate of slopes and intercepts for simple linear regression. Test the hypothesis that a simple linear regression is significant. Compute and interpret Pearson product moment correlation coefficients.

Failure to do so will result in both the original and repeated grade being used to calculate your overall grade point average. Undergraduates will receive grade forgiveness (grade replacement) for only three course repeats; graduates, for two course repeats during his/her career at UT Tyler. DISABILITY SERVICES In accordance with federal law, a student requesting accommodation must provide documentation of his/her disability to the Disability Support Services counselor. If you have a disability, including a learning disability, for which you request an accommodation, please contact Ida MacDonald in the Disability Support Services office in UC 282, or call (903) 566-7079. STUDENT ABSENCE DUE TO RELIGIOUS OBSERVANCE Students who anticipate being absent from class due to a religious observance are requested to inform the instructor of such absences by the second class meeting of the semester. SOCIAL SECURITY AND FERPA STATEMENT It is the policy of The University of Texas at Tyler to protect the confidential nature of social security numbers.
