Course Description and Objectives
G652 is an advanced biostatistics course designed for students with an interest in the health
sciences. Students are expected to have completed at least one semester course of basic
biostatistics. Knowledge of probability and probability distributions, concepts of estimation and
hypothesis testing are assumed. Topics covered in this course include multiple linear regression,
multi-factor analysis of variance, analysis of covariance, analysis of repeated measures, logistic
regression model, and survival analyses.

Upon completion of the course, students are expected to understand the appropriate statistical
models for various outcomes and be able to interpret results using statistical techniques covered
in this course. Students are also expected to conduct simple analyses using SPSS on personal
computers.

Textbook
Principles of Biostatistics, 2nd Edition, by Pagano and Gauvreau
Lecture notes will be accessible from the following web site:
       http://www.biostat.iupui.edu/~sgao

Prerequisite
G651

Meeting Time and Place
Tuesdays, 5:45 – 8:25 pm, Regenstrief 4th floor, Classroom (RG4147).

Office Hours
Thursday, 2:30 – 4pm.

Homework and Grading
There will be 12 homework assignments (10 best grades will be used for final grade), one
midterm test and one comprehensive final examination.

Class materials and homework assignments will be posted on Oncourse website. No late
homework will be accepted. The final course grade will be determined using the following
weighting scheme:
       homework       40%
       Mid term       30%
       Final exam     30%
