Biostatistics
Statistics is a discipline which provides tools for making decisions under conditions of uncertainty. Biostatistics applies the discipline to medical and biological data. The study of biostatistics includes design and analysis of experimental studies such as clinical trials and non-experimental studies, theory of probability and statistics, mathematical and statistical modeling, and knowledge of methodology used to evaluate the properties of statistical procedures. It also includes a competency in computers, which encompasses programming, statistical software use, and database management. Biostatistical methods are utilized in almost all medical research.

Graduate Studies Committee
- The Department's Graduate Studies Committee
consists of one faculty member from each division, as well
as a faculty member chosen to act as Chair. The committee
oversees the department's curricula, academic and degree requirements,
and acts as a liaison between the department and the Office
of Graduate Studies.
- Academic Advisor
- The student will be assigned an academic
advisor to help the student throughout his/her program with
course selections and general advice.
- Research Advisor
- Also called a mentor, leads the student
through his/her thesis requirements. A faculty member may
be both an academic advisor and a mentor. The student may
change academic advisors and mentor at any time by notifying
in writing the present advisor and obtaining a letter of approval
from the new advisor.
- General Requirements
- Students must satisfy the requirements of
the School of Graduate Studies as stated in the University's
General Bulletin as well as those outlined by the specific
division. To complete the M.S. degree program under Plan A,
students must conduct a research project and write and defend
a thesis. Under Plan B, students must pass a written comprehensive
examination.
- Credit Hour Requirement
- The Master's degree requires 36 hours of
credit.
- Core Courses
- Nine hours of basic core courses are required
of all students. All courses are 3 credit hours unless noted
otherwise.
- Courses within the Divisions
- Each student selects one of the following
divisions: Epidemiology, Genetic and Molecular Epidemiology,
Health Services Research (all Plan A only) or Biostatistics
(Plan B or optional Plan A).
- General Electives for All Divisons
- Electives should be chosen in consultation
with the student's academic advisor to arrive at the required
number of semester hours when combined with core requirements.
- Waiver Procedure
- To waive a prerequisite the student will
need to submit a written request to their advisor. Upon approval
of the advisor, a memo should be sent to the director of the
division outlining the reason(s) for the request. If approved
by the division director, the memo should be forwarded to
the secretary of the Graduate Studies Committee, Joan Marold,
for the committee's review and formal approval. On approval
by the full committee, the committee chair will write a formal
letter of approval to the student and their advisor. A copy
of this letter will be placed in the student's file, and the
waiver will be noted in the student's progress report.
To waive a core course, the student must provide material
(i.e., a syllabus) to show that the course requirements have
been met by the completion of either another course or through
relevant work experience. This material should be submitted
with a memo to the academic advisor who will then forward
it to the division director. If approved by the division director
the request must be approved by the instructor of the course
to be waived. A waived course will need to be replaced by
another approved course to fulfill the credit hour requirement.
- Transfer of Credit
- A student may petition to transfer credit
from another university to reduce the credit hours of course
work necessary to receive his/her degree. Transfer of credit
from another university toward a master's degree is limited
to six semester hours of graduate-level course work taken
in excess of degree requirements at that university. No thesis
credit may be transferred.
Transfer of credit requires approval from the student's academic
advisor, the chairperson, and the dean of graduate studies.
The course work must have been taken within five years of
matriculation at Case Western Reserve University and passed
with a grade of B or better.
- Masters Thesis (Plan A)
- Students in Plan A (Epidemiology, Genetic
and Molecular Epidemiology, and Health Services Research)
are required to register for at least six hours of EPBI 651
(M.S. Thesis Research). A thesis committee, consisting of
three faculty members, customarily chaired by the student's
research advisor with the other members appointed upon his/her
recommendation by the Graduate Studies Committee. To complete
this requirement, the student must submit and successfully
defend a thesis.
- M.S. Degree with Thesis
- M.S. students pursuing the thesis option
(Plan A) must:
1) Present a thesis proposal to their thesis committee, consisting
of the mentor and two other department faculty members who
have agreed and been approved to serve on the thesis committee.
The proposal must be approved unanimously.
2) Register for thesis credit (EPBI 651
- M.S. Thesis Research). A student must continue such registration
each succeeding semester until the thesis is accepted. The
minimum acceptable registration for thesis credit is three
credit hours per semester until the thesis is complete.
However, a master's candidate who has already completed
six credit hours of EPBI 651 may, with the approval of his/her
research advisor, enroll in EPBI 651 for one credit hour,
for a maximum of two semesters. Thereafter, the student
must resume registration for a minimum of three credit hours
each semester until the thesis is accepted.
3) Defend the thesis in an oral examination
which is open to the public. The student is responsible
for distributing the announcement of the oral exam to the
department faculty at least two weeks prior to the exam.
All faculty members and students are invited to attend the
oral examination. The oral examination will be conducted
within the context of the University regulations and scheduled
at the completion of the M.S. thesis. The examining committee
is to consist of the mentor and the faculty members on the
thesis committee. A final bound copy of the thesis should
be placed in the department's library. Plan A graduation
materials, including thesis signature sheets may be obtained
from the Office of Graduate Studies.
4) Be registered during the semester in
which any part of the oral examination (master's defense)
is taken. If not registered for other courses, the student
will be required to register for one credit hour of EXAM
600 - Master's Comprehensive Exam - prior to taking the
examination.

to pass the Ph.D. general examination.
-
- Biostatistics General
Examination
- The exam is administered by three faculty
members of the department and chaired by the student's academic
advisor. The examination covers Ph.D. course work within the
discipline and should include at least three areas of concentration.
The General Examination may also cover areas of weakness in
Master's level core courses.
- EPBI 701 - Dissertation Research,
Ph.D.
- Upon written notification to the Dean of Graduate
Studies, via the Ph.D. "checklist," identifying the
university faculty member selected as a doctoral student's principal
research advisor, and with the endorsement of the department
chair, the student in pre-candidacy status will be eligible
to register for one, but not more than six, credit hours of
EPBI 701 (Dissertation Research, Ph.D.), and must
continuously maintain the limited registration for EPBI
701 until advancement to candidacy occurs.
- Advancement to Candidacy
- A literature review in the proposed
area of research and a written dissertation proposal must be
defended before a Dissertation Examination's Committee consisting
of the student's dissertation advisor, two additional members
of the department, and one member from outside the department.
Once the proposal is approved, the student advances to candidacy
(with the exception of Epidemiology) and may commence independent
research on his/her topic, leading to a written dissertation
which must represent a significant independent contribution
to existing knowledge.
In the semester following advancement to candidacy, the student
is permitted to register for up to nine credit hours of 701.
A student must register for at least 18 credit hours of EPBI
701. When a cumulative total of 18 credit hours of 701
is earned, the student may subsequently register for a minimum
of one credit hour of EPBI 701 each semester until
the dissertation is complete and defended. Once registered for
EBPI 701 hours a student must continue such registration
each succeeding regular semester until the dissertation is complete
unless granted a leave of absence.
- Leave of Absence
- The student must request in writing a leave
of absence for a period not to exceed one calendar year. This
request must be submitted to the dean of graduate studies with
the written endorsement of the student's academic department.
During the leave of absence the student must avail himself/herself
of neither aid from faculty members nor use the facilities of
the university. A leave of absence does not extend the maximum
time permitted for the completion of the degree requirements.
At the expiration of the leave the student must resume registration
unless formally granted an extension.
A doctoral student who is granted a maternity or paternity leave
of absence related to infant care will receive an extension
of the five-year limit associated with completion of the doctorate.
The length of the extension will correspond to the length of
the leave.
-
Final Oral Examination (Dissertation Defense)
- The final oral examination, chaired by the Ph.D.
mentor, consists of a defense of the dissertation in the presence
of the members of the Dissertation Examination Committee. The
defense must be scheduled with the Office of Graduate Studies
no later than three weeks before the date of the examination.
The candidate must provide a copy of the completed dissertation
to each member of the committee at least 10 days before the examination.
The student is also required to submit at least one article to
a peer-reviewed journal from their dissertation research prior
to the chairperson's authorization for awarding of degree. All
faculty and students are encouraged to attend and participate
in a student's Ph.D. examination. Scheduled defenses are announced
through the Campus
News.
The candidate will be certified as passing the final oral examination
if no more than one member of the Committee dissents. Additional
work or corrections may be required based on the results of the
examination.
- Residency
Requirement
- The doctoral residency
requirement is intended in insure a period of intensive academic
interaction with faculty and peers, and of sustained independent
research.
Graduate students are considered to be in residence when they
are fully engaged in academic work. The student's regular presence
at the university is required during fulfillment of the residency
requirement.
The formal fulfillment of residency requires
continuous registration in at least six consecutive academic
terms (fall, spring and/or summer) from the beginning of matriculation
to a period not exceeding five years after the first credited
hour(s) of dissertation research (701).
- Time Limitation
- Doctoral students have five consecutive calendar
years from the semester of the first credited 701 registration
to complete all requirements for the doctorate. Those who fail
to complete the requirements within five years may petition
for an extension of a maximum of one academic year upon recommendation
of the research advisor and the approval of the department chairperson
and the Dean of Graduate Studies. The minimum acceptable registration
during this extended period is three credit hours of 701 in
each of the two semesters.
- Graduation
- A candidate for a degree awarded by the School
of Graduate Studies must make application for the degree to
the Office of Graduate Studies by the deadline established for
that semester, which is approximately two months before the
commencement date at which the degree is expected to be awarded.
The candidate must meet all the deadlines for completion of
degree requirements set forth in the calendar. All candidates
must be registered for credit and in good standing during the
semester in which the degree is awarded.
