Overview Statistics is a means of analyzing data to gain insight into real problems. It is focused on problem solving, rather than on methods that may be useful in specific settings. Statistics is unique in its ability to quantify uncertainty. Thus statistics has become a crucial tool in all aspects of modern society, providing insight in such fields as public policy, law, medicine, the social sciences, and the natural sciences.

The Department of Statistics shares the newly emerged consensus among statisticians that statistical education should focus on data analysis and statistical reasoning rather than the presentation of a coterie of methods. As importantly, the department believes that the mathematical tools underlying statistical inference are significant and necessary for statistics education, but those tools must necessarily remain secondary in the training of statisticians. Because of these views, the statistics program strongly emphasizes its consulting service, which provides statistical consultation to all branches of the University. Through this service, statistics students gain valuable insight into all branches of the field while acquiring practical training in problem solving.

The Department of Statistics offers a broad range of courses covering all areas of applied and theoretical statistics.

Faculty The faculty consist of six full-time, one half-time, and seven adjunct appointments. The half-time faculty has a joint appointment in the department of mathematics, and the adjunct faculty have primary appointments in the departments of biostatistics, economics, and systems engineering. This collection of disciplines, in addition to the interests of the full-time faculty, ensures that the department is able to cater to the interests of diverse students.

Students Students who graduate with in-depth training in statistics enjoy a large range of opportunities. Some pursue employment in the public or private sector, working as actuaries, consultants, data analysts, or teachers, among many fields. Others do graduate study in fields such as economics, finance, mathematics, operations research, psychology, and, of course, statistics.

Interdisciplinary Major in Applied Statistics The Interdisciplinary Major in Applied Statistics provides students with the opportunity to integrate the study of statistics with another quantitatively intensive discipline. Knowledge of statistics is becoming increasingly important in many disciplines, so that students completing this major will have many options available upon graduation.

Students completing this major will be well prepared to design experimental studies and analyze data, in both their emphasis field and other areas. They will also be well prepared for graduate study in statistics, and with a modest amount of advance planning will be able to complete an MS in Statistics at UVa with one additional year of study. Students interested in the 5-year B.A./M.S. program should contact the Department’s major advisor.

The major program has four tracks: Biostatistics, Econometrics, Engineering Statistics, and Mathematical Statistics. The prerequisite for all tracks: Single variable calculus through the second semester, fulfilled by one of Math 122, Math 132, APMA 111.

Minor in Statistics and Data Analysis The minor in statistics and data analysis is designed to meet the needs of several types of students: the student interested in applying statistics to some other field, the student interested in exploring a future career in biostatistics or applied statistics, the student interested in a career in actuarial statistics, or the mathematically minded student interested in graduate study in statistics.

Requirements for Minor in Statistics and Data Analysis Five (5) courses selected from: all STAT courses numbered 300 or above, MATH 312 and 511. These five courses must include STAT 512 and, at most, one of MATH 312 or STAT 500.

With consent of the statistics faculty, a student who has had an appropriate introductory statistics course in another department may be exempted from the MATH 312/STAT 500 requirement. Such a student still needs to take five courses from among MATH 511 and all STAT courses numbered 300 or above.

Courses used to satisfy the minor in statistics and data analysis cannot be used to satisfy the requirements of another major. For example, a student who takes MATH 310/312 to satisfy the requirements of the major in mathematics, must take five additional courses from MATH 511 and the STAT courses numbered 300 or above (excluding STAT 500).

Sample Programs The following are examples of programs for a student intending to pursue the minor in statistics and data analysis:

  • A general program in applied statistics: STAT 500, 512, 513, 516, 313.
  • A general program in biostatistics: STAT 500, 512, 531, 514, 301.
  • An actuarial preparatory program: MATH 312; STAT 512, 519, 540, 541.
  • A program for graduate study in statistics: MATH 312, 511; STAT 512, 513, 519. MATH 351 and 531 are also recommended.

Students should be aware that, except for MATH 312, 511; STAT 500, 512, 513, and 519, all courses for the minor in statistics and data analysis are offered in alternate years. Please consult the department’s Web site for the offering schedule.
