The Department of Statistical Science offers the Doctor of Philosophy and the Master of Science degrees in statistics. The degree program provides a balance between statistical theory and applications of statistical methods. Emphasis is placed on acquiring research, consulting, and teaching skills that are applicable to the biomedical sciences, the natural sciences, academe, business and industry, and behavioral and social sciences.
Applications from students with undergraduate degrees in business, computer science, engineering, mathematics, natural or life sciences,or behavioral or social sciences are welcome. Applicants should have a foundation in multivariable calculus and linear algebra. The GRE General Test (verbal and quantitative) is required.
The Department offers financial assistance for its doctoral degree candidates. An assistantship provides a stipend at a competitive level and tuition remission. An application to the graduate program in statistics is also considered an application for an assistantship. Special awards are available for outstanding students.
