PhD in Statistical Science Southern Methodist University - Moody School of Graduate and Advanced Studies

Introduction
The Department of Statistical Science began offering a Ph.D. in Statistical Science in 1968. Since that time it has awarded over 185 Ph.D. degrees. The courses in the Ph.D. curriculum in Statistical Science at SMU provide our students with the strong theoretical foundation in mathematics, statistical inference, and probability needed for students pursuing a research-oriented Ph.D. degree. They also acquire extensive experience in statistical applications and practice that will enable them to take leadership roles in innovative uses of statistical science in industry, government, and many other diverse fields. The emphasis in the Ph.D. program is on developing fundamental breadth and depth in both theory and applications.
Admissions
Admission Requirements
The minimum requirements for admission to the Ph.D. program in Statistical Science are as follows:
- Applicants must hold a Bachelor's degree and must have taken mathematics courses through advanced calculus and linear algebra.
- A degree in a major such as mathematics, statistics, or engineering is preferred.
- Excellent English communication skills (both speaking and writing) are required.
Applicants must provide:
- Transcripts from all institutions attended (post-high school; unofficial documents can be uploaded to your application).
- 3 Letters of Recommendation.
- Résumé.
- Statement of Purpose.
- GRE Scores.
- International applicants must provide English Language Proficiency scores if their degree does not meet our waiver requirements.
- A Video Essay is also required for all international applicants to any master’s or doctoral program in the Department of Statistical Science, regardless of English Language Proficiency score.
Curriculum
Degree Requirements
The Ph.D. in statistical science requires a minimum of 60 credit hours, no more than 12 of which can be in dissertation research. Students must complete a minimum of three years of graduate academic work, at least one of which is in full-time residence on the campus of SMU or at a research facility approved by the departmental faculty and the dean of Moody School. Students must satisfy all curricular requirements as specified by the University and by the departmental faculty. Students must pass the Comprehensive Exams and the Ph.D. Qualifying Exam, and the prospectus exam, and complete and defend a dissertation.
