Overview

    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.

Bachelor of Science in Statistics

    The Statistics major requires the completion of 38 credit hours in Statistics, 16 hours of Mathematics, 3 hours of Computer Science and 3 hours of Technical Writing. Specific requirements can be found on the department website.

    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.

    Cooperative Education and 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.

Minor in Statistics

    Requirements: 18 hours

    1. Completion of an introductory sequence: 3005-3006, 3615-3616 or 4705-4706; Note that 3604 may substitute for 3615 if taken before the minor was declared.
    2. 4204 or 4214; Note that 4214 can only count for part (2) or (3), not both.
    3. 6-9 credit hours from 3504, 4004, 4214, 4444, 4504, 4514, 4524, 4534, 4804, Math 4454, or ISE 4404; Note that Econ majors or minors may use Econ 4304 to substitute for Stat 4804.
    4. 3 hours for part (3) may come from 2004, 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).

Laboratory for Interdisciplinary Statistical Analysis (LISA)

    Associated with the statistics department, the Laboratory for Interdisciplinary Statistical Analysis (LISA) 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 Curriculum for Liberal Education (see "Academics"), toward the College of Science Core (see first part of this chapter), and toward the degree in statistics. Satisfactory progress toward the B.S. in Statistics requires that:

    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:

    1. Upon having attempted 72 semester credits (including transfer, AP, advanced standing, credit by examination, course withdrawal) majors must have completed the following courses with grades of C- or better: STAT 3005, 3006; MATH 1205, 1206, 1114, 1224, 2224, and not have taken any MATH or STAT designated course for the degree more than twice, including attempts ending in course withdrawal.
    2. Upon having attempted 90 semester credits, students must have an in-major grade point average of 2.0 or above.

Course Duplications

    No credit will be given for 2004 if taken with or after any other statistics course; MASC 1034, STAT 3604 if taken with or after any statistics course except 2004, 3104. BIT 2405 may not be used as a substitute for credit as a statistics course unless the student was officially registered as a Business major at the time BIT 2405 was taken.

Computer Literacy

    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.

Course Projects

    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.
