Welcome to Math 225: Introduction to Biostatistics! This is a one semester course which will introduce
you to probability and statistical inference. At the end of this course, you will be able to:
1) Gain a solid understanding of the foundations of probability and statistical inference as applied
to clinical trials, medicine, and other applications of a biological nature
2) Describe data sets using both graphical tools and numbers, such as mean and standard deviation
3) Understand the variation inherent to a sample from a population
4) Make inferences about a variable in question (Hypothesis Tests and Confidence Intervals)

The course calendar that follows will briefly describe each of the topics that we will cover. The class will,
for the most part, follow the textbook, Biostatistics for the Biological and Health Sciences by Triola and
Triola. Although not enforced, class attendance and reading of the designated sections of the text prior
to class are highly recommended.

Should you ever need help with this course, there are several great options available to you:
1) Ask a classmate for help
2) Stop by my office during office hours or make an appointment to see me
3) Departmental Tutoring – Meet one-on-one with former Statistics students.
4) Meet with the TA for our course. Hours and location forthcoming.

Academic Integrity: A student found cheating on an examination or assisting others in the course of an
examination will receive an F for the course and will be subject to further sanctions. Copying another
student’s assignment is considered cheating and will result in receiving a 0 for that assignment. As
previously stated, you are encouraged to work together on homework assignments. However, each

Information for Students with Disabilities: Duquesne University is committed to providing all students
with equal access to learning. If you think you have a disability requiring accommodations, you must
register with the Office of Freshman Development and Special Student Services in 309 Duquesne Union
(412-396-6657) in order to receive reasonable accommodations in this course. Once a disability is
officially documented at Duquesne by this office, and with your permission, instructors will receive
letters outlining the reasonable accommodations they are required to make. Once I have received this
letter, you and I should meet to coordinate the way these will be implemented in this course. For more
information, go to http://www.duq.edu/special-students/policies.cfm

Calculators: A calculator is highly recommended but not required. You do not need to go out and buy a
graphing calculator - a basic calculator will be sufficient for our course. Using your cell phone as a
calculator is not permitted since phones are meant as communication devices (See Academic Integrity
above).
