Courses may be chosen in related fields (economics, mathematics, finance, management, computer science, engineering, public health) with approval of the advisor.
Doctor of Philosophy in the field of statistics—Prerequisite: A master’s degree in statistics or a related discipline. The main requirement is a strong background in mathematics, including courses in advanced calculus, linear algebra, and mathematical statistics. Some deficiencies may be made up concurrently during the student’s first year. In some instances, a student may enter the Ph.D. program with a bachelor’s degree.

In addition to its degree programs, the Statistics Department offers a graduate certificate in survey design and data analysis.
With permission, a limited number of 100-level courses in the department may be taken for graduate credit; additional course work is required. See the Undergraduate Programs Bulletin for course listings.
