About the Program


The Doctor of Philosophy program in Statistics prepares students for careers in university teaching and research or in government or industrial research. Students entering the program spend four semesters acquiring a basic background in probability, mathematical statistics, and applied statistics and take general examinations on these subjects. More specialized study follows with the thesis research, which usually begins in the third year. This research may be concentrated in any area of statistics or probability in which a faculty member is interested. Students also have the opportunity to gain experience in applied statistics through participation in statistical consulting. Completion of the Ph.D. program normally requires three to five years.

A thesis must be submitted in final form, presenting new results of sufficient importance to merit publication. These results may be theoretical advances in probability or statistics, or methodological advances in the application of probability or statistics. The thesis must be accepted by the advisory committee. The student must present the contents of the thesis in an open examination.

Additional Information


Qualifying Examination: There are four Ph.D. qualifying examinations that cover material in methodology, probability, mathematical statistics, and computational statistics and are based on the core courses of the first year of graduate study in statistics.

Preliminary Examination: A student who has submitted an approved plan of study and passed the qualifying exams is required to take a preliminary exam. The purpose of the preliminary exam is to test the preparedness of the student for research. The preliminary exam is an oral exam that is administered by the student’s Ph.D. advisory committee. The student will then be recommended to the Graduate School for admissions to candidacy for the Ph.D degree.

Teaching Experience: Every doctoral candidate is required to teach at least quarter-time for one semester unless decided otherwise by the department.
