The Field of Statistics offers two graduate degree programs: an MS/PhD degree in Statistics and a Masters of Professional Studies degree in Applied Statistics. The field does not offer a Masters degree in Statistics.

The PhD program is intended to prepare students for a career in research and teaching at the University level or in equivalent positions in industry or government. A PhD degree requires writing and defending a dissertation. Students graduate this program with a broad set of skills, from the ability to interact collaboratively with researchers in applied fields, through the formulation and computational implementation of novel statistical models and methods to demonstrating mathematically that these methods have desirable statistical properties. Cornell's PhD alumni have gone on to high profile positions in all of academia, industry and government.

The Master of Professional Studies (M.P.S.) degree in Applied Statistics is for persons interested in professional careers in business, industry or government. The M.P.S. program has three main components:

- A two-semester core course covering a wide range of statistical applications, computing, and consulting
- An in-depth statistical analysis project
- Elective coursework drawn from the resources of the Department of Statistical Science.

The program can be completed in one year by a well-prepared student with the equivalent of an undergraduate degree in statistics or applied mathematics. Students with less preparation can make up any missing prerequisites while at Cornell; in this case the program will take one to two years to complete.

M.P.S. or M.S./Ph.D.?

Statistics does not offer admission for those interested a terminal master's degree, but we do offer admission for those interested in pursuing a master's leading to a Ph.D. We also offer the M.P.S. in Applied Statistics, which is normally a one-year program that does not carry financial aid.

The M.P.S. is intended for persons who want a short-term (one year) master's degree so as to go into business, industry, or government statistical work. The M.P.S. is not equivalent to an M.S. on several counts: the M.P.S. has a project (a large-scale data-analysis project) rather than a thesis or a qualifying exam (which would be the case for an M.S.). The mathematical probability/statistics component of the M.P.S. is less than it would be for an M.S. (which would be considered the first part of a Ph.D.).

The admissions procedures are completely independent: at Cornell, if you want to go on for a Ph.D. after the M.P.S. you must to apply as a new student to the Ph.D. program; you would be considered as part of the "pool" of Ph.D. applicants and, if admitted, you might be able to apply some of your M.P.S. coursework, but there is no guarantee. The Ph.D. in Statistics at Cornell enrolls about 2 to 4 students each year; the M.P.S., about 20 to 25.

If you are applying for the M.P.S., please make clear your clear if you are applying for Option 1 or Option 2.

**Application:**

In their transcripts applicants must show strength in the mathematical sciences. Applicants must also demonstrate strong motivation for advanced study in statistics. Submission of GRE general test scores is recommended.

In the broadest possible terms, the purpose of the graduate program in the Field of Statistics is to prepare its students for a career in Statistical Science, with coverage that is sufficiently deep in its coverage of core principles and methods and sufficiently broad in its coverage of application areas to prepare its students for future employment and success in a diverse array of environments. Specific program goals include the following:

- Attract the best possible graduate students and provide those admitted to the program with the financial and research resources necessary for achieving their educational goals.

- Provide advanced training through coursework and mentored research to help graduate students gain the skills and experience needed to successfully pursue a career as a statistician in academia, government or industry.

- Prepare graduate students for future leadership in research and scholarship, challenging those students to reach the highest possible level of achievement.

- Facilitate completion of graduate degrees in a timely manner.

### Assessment for M.P.S. and PhD degrees:

The M.P.S. program consists of coursework and an applied project and assessment is conducted through course exams, assignments and performance on the project.

The PhD program requires coursework, completion of an Admission to Candidacy Exam and a Thesis Defence. Depending on a coursework performance, students may also be required to sit a qualifying exam.

Upon completion of the Ph.D. degree, students will have

- Demonstrated mastery of statistical theory and methods;
- Achieved breadth and diversity of knowledge through elective coursework and research/teaching experiences;
- Demonstrated the ability to work collaboratively across disciplines, communicating statistical principles, methods and results to a lay audience;
- Demonstrated a high level of proficiency in oral and written communication skills appropriate for a career in either (i) advanced research and/or teaching at a college or university; or, (ii) advanced research in government and industry;
- Demonstrated the ability to independently conduct, document and defend original research contributions having the potential to advance the field of statistical science.

### The M.P.S. program in Applied Statistics

The MPS program in Applied Statistics is a two-semester program designed to prepare students for careers as statisticians in industry. Incoming students are expected to have mastery of calculus, linear algebra, and basic statistics as well as some computer programming experience. Statisticians are in great demand by industry and nearly all of the program’s graduates obtain employment in their chosen field. A few of them decide instead to pursue a PhD in statistics or another field.**Expected Learning Outcomes**

Upon completion of the MPS degree, students will have

- Demonstrated mastery of basic statistical theory and methods;
- Developed proficiency in the use of statistical software;
- Achieved breadth and diversity of knowledge through elective courses;
- Demonstrated the ability to creatively use statistical methods to solve real-world problems.
- Demonstrated the ability to work in teams;
- Demonstrated a proficiency in oral and written communication skills appropriate for a career in industry.

**Assessment of Learning Outcomes**

The learning outcomes will be assessed by

- Completion of STSCI 5080 (Probability Models and Inference) or STSCI 4090 (Theory of Statistics) and STSCI 4030 (Linear Models and Matrices)
- Completion of STSCI 5010 (Applied Statistical Analysis), which teaches SAS, and STSCI 4030, which teaches R.

- Completion of the required oral and written reports in STSCI 5999.
- Performance in these tasks will be assessed through grades in each of the classes listed above, and average elective grade for Outcome c.
