## Overview

The department offers a program leading to the degree of Bachelor of Science in Statistics. The program provides a strong basis in both applied and theoretical statistics and prepares a student for the pursuit of graduate study in statistics or for employment by industry or government. In addition, the department serves many of the disciplines within the University through course offerings which provide basic statistical skills necessary to the pursuit of studies in these disciplines.

### General Statistics Courses

STAT 110 is a first course in statistics at the freshman level which is devoted to the basic concepts of statistical thinking, including techniques of collecting, organizing, and presenting statistical data.

STAT 201 emphasizes the concepts and methods of statistical inference. Any of STAT 110, MATH 111, or MATH 115 provide good preparation for STAT 201.

STAT 509 or STAT 515 provide thorough introductions to statistical methods, followed by advanced methods in STAT 506, 518, 519, 520, 525, 530. STAT 511, 512, 513 provide an introduction to the theory of probability and mathematical statistics.

### Degree Requirements

*(128 hours) *

The Bachelor of Science in Statistics degree program is designed to give the student a balance of skills in statistical theory and applied statistical data analysis. The program is broad, yet rigorous enough to prepare a student to work in business, industry, or government as a statistician, or to pursue graduate work in statistics.

### Integrated B.S./M.S. in Statistics

The integrated B.S./M.S. education plan is designed to permit outstanding statistics students to pursue both a B.S. degree and an M.S. degree in statistics in five years. During or after the semester in which the student completes 90 credit hours toward the B.S. degree in statistics, the student may apply to the department to participate in the integrated plan. The application will require the approval of the undergraduate advisor, the graduate director in statistics, and the dean of the College of Arts and Sciences. Provisional admission to and continuation in the integrated plan will require at least a 3.40 overall GPA and at least a 3.40 GPA in both undergraduate statistics and mathematics courses. Students opting for the plan should complete their B.S. requirements by the end of their eighth semester of study. Students admitted provisionally in the plan must take the general Graduate Record Examination before the end of their seventh semester. Continuation in the integrated plan after the eighth semester requires that the student be admitted into the graduate program in statistics through The Graduate School. Upon admission to the graduate program, the student may be eligible for financial assistance from the department. In the fifth year during the first or second summer of graduate study, the student may be eligible for a graduate teaching or research assistantship.

### Cognate or Minor for Nonmajors

Students with majors in other departments may supplement their major program of study by selecting a cognate or minor in the statistical sciences.

**Cognate in Statistics.** All courses in statistics numbered 500 and above may be used for cognate credit.

**Minor in Statistics.** The minor consists of 18 hours of 500-level statistics courses. Minor credit will be given for at most one of 509, 515.

**Minor in Actuarial Mathematics and Statistics.** The minor consists of the prerequisite courses MATH 141, 142, and 241 or 250, plus 18 hours of mathematics and statistics courses chosen as follows: MATH 511 {=STAT 511}, STAT 512, 513; and one course from three of the following four categories: 1) MATH 514 {=STAT 522}; 2) STAT 510, 520; 3) MATH 526, 544; 4) MATH 570, 574.
