Doctor of Philosophy
The Department of Statistics offers programs leading to a Ph.D. in statistics. The program is flexible enough to be individually planned around prior experience and in accord with professional goals.
During the first year of the program, students are strongly encouraged to meet with each individual faculty member to discuss possible research topics. The student should select an advisory and examining committee by the end of the first year.
Ph.D. Program in Statistics:
To be admitted with full status into the Ph.D. program, the applicant must:
- Hold a baccalaureate degree from an educational institution of recognized standing.
- Have had four courses in Math at the university calculus level or above.
- Have had several courses in statistics.
- Have had at least one programming language.
Must have at least a 3.0 or equivalent cumulative grade point average (GPA) on all related courses at the baccalaureate level.
Students not holding a master's degree in statistics or a closely related field will not be admitted to the Ph.D. program in statistics. These students must first apply to the M.S. program in applied statistics and complete the M.S. degree.
Preferably, applications should be submitted to the Graduate School before March 15 of the upcoming academic year.
Official transcripts (transcripts having an appropriate seal or stamp) of all previous undergraduate and graduate records must be received by the Graduate School before the application is complete. When a transcript is submitted in advance of completion of undergraduate or graduate studies, an updated transcript showing all course credits and grades must be provided prior to initial registration at NDSU.
Three letters of recommendation are generally required before action is taken on any application.
The TOEFL examination is required of international applicants.
The student must first apply in our program through the Graduate School and be accepted in full or conditional status before he/she is eligible for an assistantship in the Department of Statistics.
Teaching assistantships are available. To be considered for an assistantship, a completed Graduate School application, official transcripts, and three letters of reference must be submitted to the Graduate School no later than March 15. International students must also submit a TOEFL score.
The program for the Ph.D. degree requires an additional 30 credits of course work beyond the M.S. degree and 30 hours of research. An oral defense of a dissertation is required.
