Course Number: OSH 637
Credit Hours: 3
Bassam H. Atieh, Sc.D.
Biostatistics and Probability
Course Description and Prerequisite(s)
The study and application of biostatistics and probability distributions in environmental and
health related sampling. Emphasis is given to hypothesis testing and graphical determination of
confidence intervals. This course will also cover the use of log scales and their application in
log-normal distributions. This course is offered to graduate students only.
Prerequisites: MAT 135 or PSY 300, or instructor's approval.
Course Objectives (1,3)
By the end of this course:
- Students will be able to choose the appropriate method to analyze collected data.
- Students will be able to graphically analyze data and draw conclusions.
- Students will be able to apply statistics in health science related fields, and to determine
employers' compliance with OSHA standards and guidelines.

Academic Honesty Policy
Murray State University takes seriously its moral and educational obligation
to maintain high standards of academic honesty and ethical behavior. Instructors are
expected to evaluate students' academic achievements accurately, as well as ascertain
that work submitted by students is authentic and the result of their own efforts, and
consistent with established academic standards. Students are obligated to respect and
abide by the basic standards of personal and professional integrity.
Violations of Academic Honesty Include
Cheating - Intentionally using or attempting to use unauthorized information such as
books, notes, study aids, or other electronic, online, or digital devices in any academic
exercise; as well as unauthorized communication of information by any means to or from
others during any academic exercise.
Fabrication and Falsification - Intentional alteration or invention of any information
or citation in an academic exercise. Falsification involves changing information whereas
fabrication involves inventing or counterfeiting information.
Multiple Submission - The submission of substantial portions of the same academic
work, including oral reports, for credit more than once without authorization from the
Plagiarism - Intentionally or knowingly representing the words, ideas, creative work, or
data of someone else as one's own in any academic exercise, without due and proper
Instructors should outline their expectations that may go beyond the scope of this policy at the
beginning of each course and identify such expectations and restrictions in the course syllabus.
When an instructor receives evidence, either directly or indirectly, of academic dishonesty, he
or she should investigate the instance. The faculty member should then take appropriate
Disciplinary action may include, but is not limited to the following:
1) Requiring the student(s) to repeat the exercise or do additional related exercise(s).
2) Lowering the grade or failing the student(s) on the particular exercise(s) involved.
3) Lowering the grade or failing the student(s) in the course.
If the disciplinary action results in the awarding of a grade of "E" in the course,
The student(s) may not drop the course.
Faculty reserve the right to invalidate any exercise or other evaluative measures if substantial
evidence exists that the integrity of the exercise has been compromised. Faculty also reserve
the right to document in the course syllabi further academic honesty policy elements related
to the individual disciplines.
A student may appeal the decision of the faculty member with the department chair in
writing within five working days. Note: If, at any point in this process, the student alleges
that actions have taken place that may be in violation of the Murray State University
Non-Discrimination Statement, this process must be suspended and the matter be directed to
the Office of . Any appeal will be forwarded to
the appropriate university committee as determined by the Provost.
