Graduate Programs in Public Health
GPH 716 Biostatistics – Fall 2017
Credits - 3
Description
This course provides you with an introduction to the procedures used in the summarization, analysis, interpretation, and presentation of research data. Topics include sampling, experimentation, measurement, descriptive statistics, correlation, probability, confidence intervals, testing hypotheses, 2-way tables, and simple linear regression. This course is deliberately broad and not intended to give students an in-depth understanding of statistical testing, analysis of categorical data or regression analysis. Rather, its intent is to provide an overview of some of the main areas of statistics and a working knowledge of basic summary statistics, graphs, and simple statistical tests for hypothesis testing. At the end of the course a student should be able to evaluate simple statistical usage in everyday life and their own discipline, especially in relevant research publications; and interact knowledgeably with statisticians in planning, conducting, analyzing, and reporting research projects.

Assignments
Discussion Board:
Each student is expected to post at least twice each week. One post should be an original contribution to the discussion. A second or sequential post should be in response to a classmate’s post. Initial discussion posts must be submitted by Sunday at 11:59 pm. For most weeks, that means you must have completed the reading by this time. At least one response post must be completed by Wednesday at 11:59 pm of the week the question is assigned.
If the initial post and response are not submitted within the discussion week you will be given a zero. Posts submitted after the discussion week will not be graded.
Quiz:
In Week 4 you will complete a quiz. This quiz will cover information from Weeks 1 through 4. This quiz will be administered through the Blackboard quiz tool. You will have one chance to take this quiz. The quiz will be graded automatically.
Written Assignments:
In Weeks 2, 3, 5, 6, and 8 you will complete written assignments. For each assignment carefully read through the prompt in Blackboard and review the rubric. If you have any questions about these assignments, make sure to ask your instructor.
Final Project:
This course provides you with an introduction to the procedures used in the summarization, analysis, interpretation, and presentation of research data. The final project for this course will apply the skills you learn in these areas to a public health data set and integrate the results into a final report. This report will be similar to a research article that you would submit to a journal, except that you will not be performing original research.
Please review the Final Project Document for a full description of the assignment requirements and expectations. This assignment will be submitted in Week 7. Throughout the course you will work on pieces of your final project.
