# Statistics M.S.

The Master of Science in Statistics program is designed for students who wish to pursue careers as practicing statisticians in industry, government, or academia. It is also designed to prepare students for community college teaching or entry into a Ph.D. in Statistics degree program. The degree is also valuable for people working in other fields who need mastery of a broad range of statistical methods.## Admission

### Program prerequisites

Transcript(s) must show successful completion of at least the following undergraduate courses: Advanced Statistical Methods, Introductory Analysis/Advanced Calculus, Linear Algebra, and Differential Equations. These courses are equivalent to PSU's Stat 452 or higher, Mth 311, Mth 261, and Mth 256.

In addition to program prerequisites, applicants must meet the university's minimum admission requirements including English language proficiency.

This program admits once per year for fall term only. See instructions on how to apply: https://www.pdx.edu/math/graduate-application-instructions.

## Degree Requirements

Candidates must complete an approved 45-credit program, which includes at least 33 core credits in courses with the Stat prefix. In addition, students must pass two examinations, one in Mathematical Statistics and one in Applied Statistics.

A student must have a minimum 3.00 GPA on the courses applied to the program of study, as well as a minimum 3.00 GPA in all graduate-level courses taken at PSU. Although grades of C+, C, and C- are below the graduate standard, they may be counted as credit toward a master’s degree with the specific written approval of the department if taken at PSU after the term of formal admission to the graduate program.

Students are responsible for knowing University-level graduate policies and procedures for obtaining the degree. These policies and procedures are in the Graduate School section of the PSU Bulletin. Several of the most frequently asked about University-level graduate policies and procedures can also be found on the Graduate School website.

Other statistically oriented courses outside the Department and other mathematics courses may be substituted, but must be approved as electives by the statistics graduate program adviser. "Approved as elective" means that it is approved inside the 12 elective credit hours **but not** inside the 33 statistical credit hour core requirements. A course or sequence cannot be counted both within the 33-hour core and as an elective course or sequence.

## MS Examinations

Students must pass two examinations, one in Mathematical Statistics which covers Stat 561, Stat 562, Stat 563 and one in Applied Statistics which includes the core topics covered in Stat 564, Stat 565, and Stat 566 . Examinations are offered twice a year, the week prior to the start of fall term and during the first week of spring term. Students may take any examination at most two times. Students must be registered for and complete at least one graduate credit during the term(s) in which they take an exam. For complete details see the full MS Exam Policy (https://www.pdx.edu/math/ms-exam-policy).Grading Policy for the MS Exam in Applied Statistics

The Applied Statistics Exam is comprised of two components:

- Applied regression analysis
- Design of experiments and ANOVA

Both components consist of a written exam portion and a separate, in-laboratory, statistical computing applications portion. The Applied Statistics Exam may be repeated once; that is, a maximum of two tries is permitted.

A Pass (P) or Fail (F) is given on each component.

- Two P's equal a PASS on the exam.
- One P equals a CONDITIONAL PASS on the exam. The Examination Committee will inform the student of the requirements for removal of the Conditional.
- Two F's equal a FAIL on the exam. In this case the entire exam must be retaken.
