The curriculum in mathematical sciences promotes understanding of the mathematical sciences and their structures, uses and relationships to other disciplines. To this end, the scholarly growth of the faculty and students in the mathematical sciences is nurtured through study, research and a high standard of teaching. The curriculum provides a sound foundation for the student seeking to enter a career with a technological orientation or for the student who wishes to pursue graduate study in applied mathematics, biomathematics, mathematics, operations research, statistics, teaching mathematics in secondary schools or related fields.

A Bachelor of Science is offered jointly by the Department of Mathematics and Applied Mathematics and the Department of Statistical Sciences and Operations Research. In the Department of Statistical Sciences and Operations Research, students pursuing the Bachelor of Science in Mathematical Sciences can choose a concentration of statistics, which teaches students how mathematical models used in the investigation of uncertain phenomena are developed and applied to experimental and nonexperimental data.

## Student learning outcomes

**Upon completing this program, students will know and know how to do the following:**

- Understand basic statistical concepts and terms
- Perform data collection
- Analyze data
- Use statistical software packages
- Understand probability and inference
- Understand calculus and linear algebra

## Special requirements

The B.S. in Mathematical Sciences requires a minimum of 120 credits. Along with the general education requirements of the College of Humanities and Sciences and the undergraduate degree requirements, students are required to take core courses and fulfill specific requirements for the degree.

Based on the results of the Mathematics Placement Test, students may be required to take MATH 151. No more than one course in mathematics (MATH) at the 100 level can count for the general requirements toward the degree. Credit for 100-level mathematical sciences courses cannot be applied toward the mathematical sciences courses required for the major in mathematical sciences.

### Double major

Students who meet the requirements for two of the concentrations within the mathematical sciences curriculum can receive a double major. To initiate a double major, students must obtain the appropriate form from the Office of Records and Registration.

### Second baccalaureate degree

For students possessing a bachelor’s degree and wishing to gain undergraduate preparation in an area of mathematical sciences, second baccalaureate degrees are offered through the department. For detailed information about these programs, refer to the “Academic regulations and general degree requirement” section of this bulletin

## Accelerated B.S. and M.S.

The accelerated B.S. and M.S. program allows qualified students to earn both the B.S. and M.S. in Mathematical Sciences with a concentration in statistics in a minimum of five years by completing approved graduate courses during the senior year of their undergraduate program. Students in the program may count up to nine hours of graduate courses toward both the B.S. and M.S. degrees. Thus, the two degrees may be earned with a minimum of 141 credits rather than the 150 credits necessary if the two degrees are pursued separately.

Students holding these degrees will demonstrate a comprehensive understanding of basic statistical concepts, probability and inference, general linear modeling, calculus, and linear algebra. They will know how to select appropriate samples and conduct appropriate experimental data collection methods. Additionally, students will be able to use statistical software packages to perform appropriate analysis of data, including knowledge of the assumptions associated with the procedures and how to determine the appropriate procedure to use. Students will know how to clearly and concisely present technical information in writing and through oral presentations. The program will also provide students with opportunities to participate in research projects, internships and other training programs where they develop the skills to evaluate, refine and apply what they learn in the classroom.

## Admission to the program

Minimum qualifications for admittance to the program include completion of 90 undergraduate credit hours including STAT 212, STAT 305, STAT 321, STAT 309 and STAT 310; an overall minimum GPA of 3.0; and a minimum GPA of 3.3 in mathematics and statistics course work. Successful applicants would enter the program in the fall semester of their senior year. (Optional: Students who do not meet the minimum GPA requirements may submit GRE scores to receive further consideration.)

Undergraduate students must have departmental approval to participate in an accelerated program and must apply for admission to the master’s program prior to beginning their final year of full-time undergraduate study. The entry term for the master’s program will be the next available admission term following the last semester of undergraduate study. Admission to the master’s program is provisional until the undergraduate degree has been conferred. Upon completion and conferral of the undergraduate degree, students are fully admitted to the master’s program.

Candidates should submit applications for admission immediately following the spring of their junior year, but no later than the M.S. program admission deadline. Three reference letters (at least one from a statistics faculty member) must accompany the application. The adviser of graduate studies for the mathematical sciences master’s program with a concentration in statistics will provide guidance of students in this program. Students who are interested in the accelerated program should consult with the faculty adviser to the statistics concentration of the M.S. program before they have completed 90 credits.

Once admitted into the accelerated program, students must meet the standards of performance applicable to graduate students as described in the “**Satisfactory academic progress**” section of the Graduate Bulletin, including maintaining a 3.0 GPA. Guidance to students admitted to the accelerated program is provided by both the undergraduate mathematical sciences adviser and the faculty adviser to the graduate program.

## Degree requirements

The Bachelor of Science in Mathematical Sciences degree with concentration in statistics will be awarded upon completion of a minimum of 120 credits and the satisfactory completion of all undergraduate degree requirements as stated in the Undergraduate Bulletin.

A maximum of 12 graduate credits may be taken prior to completion of the baccalaureate degree. These graduate credits may be used to satisfy required major electives or open elective credits for the undergraduate degree. Nine of these credits are shared credits with the graduate program, meaning that they will be applied to both undergraduate and graduate degree requirements.

The graduate statistics courses that may be taken as an undergraduate, once a student is admitted to the program, are in the table below.

Course | Title | Hours |
