Mathematics and Statistics

Mathematics is an art, a pure science, a language, and an analytical tool for the natural and social sciences, a means of exploring philosophical questions, and a beautiful edifice that is a tribute to human creativity. The mathematics curriculum is designed to provide essential skills for students in a variety of disciplines and to provide mathematics majors with a deep understanding of mathematics as it has evolved over the past two thousand years and how it is practiced today. The statistics curriculum provides students with opportunities to analyze real data and enhance their communication skills.

Students can major in Mathematics or Mathematics/Statistics (a double major is not allowed in both majors).

Mathematics Skills Center:

This Center offers extra assistance to students in lower-level mathematics courses and other courses requiring basic mathematical skills.

 

Requirements for the Mathematics Major

The course requirements are Mathematics 101 or 111, 120 or 121, 210 or 211, 232, 236 and six advanced courses from among: Mathematics courses numbered above 236 and Computer Science 252, 254. Potential majors with especially strong preparation may petition the department for exemption from the Mathematics 232 and/or 236 requirement(s). Mathematics majors are encouraged to take Computer Science 111.

At least three of the following five areas of mathematics must be represented by the six advanced courses.

  • Algebra: Mathematics 312, 332, 342, 352
  • Analysis: Mathematics 251, 261, 321, 331, 361
  • Applied Mathematics: Mathematics 241, 245, 255, 265, 275, 315, 341, 365
  • Discrete Structures: Mathematics 333, Computer Science 252, 254
  • Geometry and Topology: Mathematics 244, 344, 354

Of the six advanced courses, at most two may be from outside the Carleton Department of Mathematics.

In addition, each senior major must complete an integrative exercise, Mathematics 400 (3 or 6 credits) which can be either a group or individual project. Majors are required to participate in the mathematical life of the department by attending colloquia, comps presentations, and other activities.

There are many patterns of courses for the major depending upon a student's mathematical interests and career goals. A guide for majors, which supplies information about suitable patterns of courses, is available on the Mathematics department web site. Those planning to attend graduate school should consider acquiring a reading knowledge of at least one of the following languages: French, German or Russian.

Major under Combined Plan in Engineering:

In addition to completing requirements for the mathematics major listed above including Mathematics 241 and 341, the student should take the following courses required for admission to engineering schools: Two terms of 100-level Physics, Chemistry 123, 224, and Computer Science 111.

Requirements for the Mathematics/Statistics Major

Class of 2018 only

A Carleton student following this option must take the following courses: Mathematics 101 or 111, 121, 211, 232, 236, 245, 265, 275 and one of 255, 315 or 365, plus two Mathematics courses above 236 (one of which may be Computer Science 324); at least one of these two courses must be taken outside of the Applied Mathematics area. In addition, the Senior Integrative Exercise is required.

It strongly recommended that students on this track take CS 111 and engage in some data analysis learning experience outside of the classroom such as an internship involving data analysis, a research experience with a statistician, either on or off campus, or a comps project that is explicitly statistical in nature.

Students interested in graduate school in statistics should consider taking Mathematics 321 (Real Analysis I).
