# Courses and Requirements

*The goal of Hamilton’s Mathematics and Statistics Department is to enable students to analyze and organize information using quantitative and statistical tools, to reason and argue logically, to employ appropriate problem-solving strategies, and to communicate complex ideas clearly and efficiently.*

Concentrators may not take any course in the Mathematics and Statistics Department numbered 224 or higher on a CR/NC basis. Concentrators may apply at most one course taken on a CR/NC basis towards the concentration.

Beginning with the class of 2020, students concentrating in mathematics must satisfy the Social, Structural, and Institutional Hierarchies requirement by completing one of Math 152, Math 498, Econ 166, Hist 226 or, for those interested in pursuing a career in education, Educ 204, Educ 206, Educ 339 or Educ 415. Students who have not completed one of these courses may petition the department to accept a course in another department as fulfilling the SSIH requirement by providing a written rationale explaining how the proposed course will help them gain an understanding of social, structural, and institutional hierarchies that is relevant to mathematics and their post-graduation plans.

Students may earn departmental honors by completing courses that satisfy the concentration with an average of 3.6 or higher, by taking a fourth full-credit elective that is at the 300 level or higher, and by making a public presentation to the department on a mathematical or statistical topic during their junior or senior year.

A minor in mathematics consists of 116, 216, 224 and two electives. Minors in mathematics may not take any course in the Mathematics and Statistics Department numbered 224 or above on a CR/NC basis. Minors in mathematics may apply at most one course taken on a CR/NC basis towards the minor.

A minor in statistics consists of five courses: 116, 216, 152, 254 and 351. Students may substitute Econ 166, Govt 230 or Psych/Neuro 201 for 152. Students may use Advanced Placement, International Baccalaureate, or A-level courses to count for only one of the five courses. Students with two or more such courses, or who want to count Econ 166, Govt 230 or Psych/Neuro 201 towards a concentration or another minor can complete the minor in statistics by selecting from the following additional courses: 352, 355, 503 or 551 for a minimum of 4 courses from the Mathematics and Statistics Department. A student with a concentration in mathematics may not minor in statistics. Minors in statistics may not take any course in the Mathematics and Statistics Department numbered 224 or above on a CR/NC basis. Minors in statistics may apply at most one course taken on a CR/NC basis towards the minor.

While all courses offered by the department satisfy the QSR requirement, students seeking an entry-level course only for this purpose are encouraged to consider COLEG 105S: A World of Impending Disaster.
