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. The statistics department also has joined with the departments of computer science and mathematics to offer a course which provides an interdisciplinary approach to the study of mathematical sciences. (Please see "Mathematical Sciences" in this catalog.)

Statistics courses for graduate students and programs leading to the M.S. (with or without thesis) and Ph.D. degrees in statistics are described in the Graduate Catalog and in a special bulletin available from the department.

Bachelor of Science in Statistics

All statistics majors are required to own specified personal computers and software. Consult the department for details.

A special brochure describing the department and the B.S. program, intended for prospective entering freshmen, is available from the department upon request.

Students with sufficiently high GPA's may obtain permission to take graduate courses during the senior year. Graduate courses may serve as undergraduate free electives or as substitutes for required courses (e.g., 5104, 5114 for 4105, 4106). Under certain circumstances, students also may begin a graduate degree program during the senior year.

Cooperative Education positions are available in industry and government, offering valuable practical experience. The department encourages participation in the co-op program.

Minor in Statistics

Requirements: 18 hours

  1. Completion of either 3005-3006 or 4705-4706;
  2. 4204;
  3. 6-9 credit hours from 3104, 3504, 4004, 4214, 4444, 4504, 4514, 4524, 4534, 4804.
  4. 3 hours may come from 2004, 2404, 3604, 3615, 4604, 4714, providing it is the first statistics course taken.

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).

The Statistical Consulting Center

Associated with the statistics department, the consulting center provides statistical assistance for research projects throughout the university community. Faculty members, staff, and students are available to aid in statistical design and analysis for any authorized research study here at the university and at other state agencies.

Satisfactory Progress

University policy requires that students who are making satisfactory progress toward a degree meet minimum criteria toward the University Core (see "Academics" chapter in this catalog), toward the Arts and Sciences College Core (see first part of this chapter), and toward the degree in statistics. Satisfactory progress toward the B.S. in Statistics requires that:

  1. Upon having attempted 70 semester credits (including transfer, advanced placement, advanced standing, credit by examination, freshman rule), students must have completed with a course grade of C- or above:

  2. CS 10443
    MATH 1114, 1224, 1205, 1206, 222413
    STAT 3005, 3006: Statistical Methods6
    STAT 3104: Probability Theory and Stat. Inference3
    Credits(25)

  3. Upon having attempted 90 semester credits, students must have an in-major grade point average of 2.0 or above.

Undergraduate Courses (Stat)

Course Duplications: No credit will be given for more than one course in each of the following groups (in parentheses) of partially duplicated courses: (3005, 3615, 4604). (3006, 3616, 4706). (4105, 4604, 4705, 4714, 4724). No credit will be given for: 2004 if taken with or after any other statistics course; 2404 if taken with or after any of 3104, 4105, 4705, 4714, 4724; 3604 if taken with or after any statistics course except 2004, 2404, 3104. MSci 2405 may not be used as a substitute for credit as a statistics course. Exceptions to this rule may be granted if the student was officially registered as a Business major at the time MSci 2405 was taken. Exceptions to the duplications involving courses approved for the minor in statistics may be granted for students who are obtaining a minor in statistics, provided that the requirements listed under Minor in Statistics have been met.

Computer Literacy: Many statistics courses involve the use of statistics software; primarily MINITAB or SAS. 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. These courses are identified by "WIN/MAC" under prerequisites.

Course Projects: Many of the upper-division course descriptions below include the word 'Project.' Those courses will usually include a major term project, either individually or 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.
