# Statistics and Data Science

Statistics — as a core discipline focusing on data-driven discovery, understanding, and decision-making — is rapidly evolving and advancing in the data science era. The new Department of Statistics and Data Science (SDS) strives to be a world-class department with outstanding scholars who will transform the university's intellectual community not only through their own activities and achievements but also through synergistic collaborations with existing faculty and departments across Arts & Sciences, the McKelvey School of Engineering, and all of the other schools at the university.

SDS offers two master's degree programs in statistics and one doctoral degree in statistics. Our master’s and PhD graduates regularly secure competitive positions at universities, at government institutions, and as statisticians and data scientists in industry. One of the most attractive features of our program is the friendly and supportive atmosphere that develops among our graduate students.

**PhD in Statistics**

Students ordinarily complete the PhD program in five years, and those students may expect up to five years of support. Continuation of support each year is dependent upon normal progress toward the degree and the satisfactory performance of duties. Students typically spend their first two years (four semesters) taking graduate courses. At the end of this time, they will have completed requirements for the master's degree. Students ordinarily start the process of finding a dissertation advisor and start their research during their second year.

A student who comes to Washington University with advanced preparation may finish in less time. Alternatively, some students find that it is advisable for them to take some preparatory courses before attempting the qualifying courses. In special cases, the time schedule may be lengthened accordingly.

Washington University's graduate student stipends are in the top 25% of stipends at similar universities, and St. Louis has a low cost of living.

**Master of Arts**** in Statistics**

SDS offers two standalone Master of Arts (AM) programs. The Accelerated AB/AM in Statistics is available only to qualified Washington University undergraduates. The AM in Statistics is available to all qualified students from any field. These programs provide students with the analytical background needed to prepare them for diverse careers, from positions in government and business to further PhD studies.

The regular AM in Statistics consists of 36 units of course work to be completed in three to four semesters. After completing a well-designed and judiciously chosen set of core courses (currently five), AM students can choose from a wide range of electives that includes several courses from other departments. AM students can also challenge themselves to take the more advanced Statistics PhD qualifier courses to prepare them for further PhD programs upon graduation. High-achieving students may also choose to complete a master’s thesis.

Another distinctive feature of our program is a practical training experience, which will typically involve an internship off campus or working in a research group on campus.

The Accelerated AB/AM in Statistics allows highly qualified undergraduate majors to earn both the AB and AM degrees with two additional semesters of work (i.e., usually a total of five years). Participants can count up to 15 units of 400-/500-level course work earned during the four years of undergraduate study (with grades of B or better) toward the AM course requirements. Counting these 15 units makes it possible to finish the master's requirements in one additional year, but the program is still fast-paced and requires a lot of intense work and some careful planning. SDS expects applicants to have backgrounds comparable to the students admitted to the regular AM program.

**Overview of Faculty Research**
