Undergraduate Coordinator: D.D. Wackerly Graduate Coordinator: A.I. Khuri Office: Griffin-Floyd 102 (392-1941) An undergraduate major in statistics is offered in both the College of Liberal Arts and Sciences and the College of Agriculture. Students planning to major in statistics should have a strong interest in mathematics and some interest in computing. A student majoring in statistics can also work toward a minor in Actuarial Science. Details of this program may be obtained from the Department of Statistics. All stu- dents who wish to major in statistics must consult a departmental adviser early in their program. ADMISSION TO THE MAJOR: Requirements for a student to be admitted to the undergraduate statistics program are as follows: the satisfactory com- pletion of MAC 3311 & 3312 or equivalent with a grade of C+ or better. The admission of all other stu- dents will be determined on an individual basis and any such admission will be conditional. The condi- tions of admission for each individual student will be established by the Department of Statisitics. Immediately after admission to the program, students are urged to consult with an undergraduate adviser in the Department of Statistics. THE MAJOR: All majors in statistics are required to complete the following core requirements: STA 4210-12; STA 4321-22 MAC 3311-13 or MAC 3472-74 MAS 3113 or MAS 3114 or MAS 4105 This is a total of 30-31 semester hours. Elective Requirements: At least 12 semester hours, in addition to the core requirements, must be completed from a variety of elective possibilities. The statistics electives include STA 4173, 4222, 4821 or Industrial Statistics. Other electives may be selected from mathematics, computer and information sci- ences, and from industrial and systems engineering. The individual program must be worked out with an adviser from the Department of Statistics. The student must receive a grade of C or better within two attempts in every core requirement course and in every course counted toward the 12 hour elec- tive requirement. The grades from all attempts to sat- isfy core requirements will be averaged together and this grade average must be at least 2.0 for all attempts to satisfy the core requirement and 12 hour elective requirement combined. Of the 42 hour core and elective credits that are required for the degree, at least 18 credits must be earned with the grade of C or better while the student is enrolled at the University of Florida. At least 12 of the 18 STA credits in the core requirement must be included in this 18 hour requirement. HONORS: For graduation with honors a student must attain a 3.5 overall upper division average. To earn high or highest honors a student majoring in statistics must: (1) obtain a 3.5 GPA in all upper division work. (2) complete a project sanctioned by a committee of advisers. This project will comprise at least 6 hours of course work outside of the core and elective requirements and will be designed to advance the stu- dent significantly towards his/her career goal. THE MINOR: A minimum of 15 hours (5 cours- es) of 4000-level statistics courses are required of all students desiring a minor in statistics. Of these, no more than 3 hours may be transfer credits. All statistics minors are required to complete STA 4210 and STA 4211. Each statistics minor whose major requires the completion of MAC 3311-13 is required to complete STA 4321-22. In addition, all students minoring in statistics are required to: complete all 4000-level statis- tics courses with a grade of C or high, take no courses counting toward the minor on an S/U basis, and count no individual study courses toward the minor. OVERSEAS STUDY: Students interested in study abroad should consult with a department advis- er or the Overseas Studies Office in 123 Tigert. GENERAL EDUCATION: The quantitative por- tions of the general education and Gordon Rule requirements obligate all students to a minimum of 6 hours of "quantitative" course work. At least 3 of these 6 hours of quantitative courses must be earned through the Mathematics Department. The remaining 3 hours of this requirement may, at the discretion of the student, be fulfilled by earning a grade of "C" or better in any of the following statistics courses.
