Welcome to Virginia Tech! We are excited that you are here planning your time as a Hokie.
Statistics courses are offered at both the undergraduate and the graduate levels for students preparing for professions in statistics, for students who need statistical tools to engage in scientific research, and for students who want to acquire knowledge of the important concepts of probability and statistical inference.
Statistics courses for graduate students and programs leading to the M.S. and Ph.D. degrees in statistics are described in the Graduate Catalog and in a special bulletin available from the department.
All statistics majors are required to own specified personal computers and software. Consult the department for details.
Internship positions are available in industry and government, offering valuable practical experience. Students participating in such an experience can receive academic credit which will count towards graduation requirements.
The graduation requirements in effect during the academic year of admission to Virginia Tech apply. Requirements for graduation are listed on checksheets. Students must satisfactorily complete all requirements and university obligations for degree completion. The university reserves the right to modify requirements in a degree program.
Please visit the University Registrar's website at https://www.registrar.vt.edu/graduation-multi-brief/checksheets.html for degree requirements.
Please visit the University Registrar website at http://registrar.vt.edu/graduation-multi-brief/index1.html to view requirements for the minor.
The department reserves the right to withhold credit if a student takes a course, the content of which is partially duplicated in a course already taken (see "Course Duplications" below).
Associated with the Department, the Statistical Applications and Innovations Group (SAIG) provides assistance for research projects to participating members of the University community and outside organizations. Statistics Department faculty members and students collaborate to design studies, analyze data, and interpret results for Virginia Tech affiliated clients and external clients in business, industry, government, and non-profit organizations. SAIG provides both experiential learning for statistics students and service to the University and beyond. To learn more, visit https://saig.stat.vt.edu/.
University policy requires that students who are making satisfactory progress toward a degree meet minimum criteria toward the Pathways to General Education and toward the degree.
Satisfactory progress requirements toward the B.S. in Statistics can be found on the major checksheet by visiting the University Registrar website at https://www.registrar.vt.edu/graduation-multi-brief/checksheets.html.
Many statistics courses involve the use of statistics software, primarily MINITAB, SAS, JMP or R. Experience with the software is not expected, but students should have familiarity with either the Windows or Macintosh operating system and have access to a computer.
Many of the upper-division courses include a project, generally to be completed in small groups. These projects are designed to give students the kind of insight and experience in realistic statistical practice that cannot be obtained in classroom lectures or short-term homework assignments.
