**STAT W 1000x and y Undergraduate Seminar in Statistics**

Prepared with undergraduates majoring in quantitative disciplines in mind,
the presentations in this colloquium focus on the interface between data
analysis, computation, and theory in interdisciplinary research. Meetings
are open to all undergraduates, whether registered for the courses or not.
Presenters are dawn from the faculty of department in Arts and Sciences,
Engineering, Public Health and Medicine. - D. Rabinowitz

*Prerequisites: Previous or concurrent enrollment in a course in
Statistics*

*1 point*

**STAT W 3997x and y Independent Research**

May be repeated for credit. This course provides a mechanism for students who
undertake research with a faculty member from the Department of Statistics to
receive academic credit; students should only register for this course with
permission of their project mentor. - Instructor to be announced

*Prerequisites: The permission of a member of the department. General
Education Requirement: Quantitative and Deductive Reasoning (QUA).*

The Department of Statistics offers three first introductory courses, STAT W1001, W1111, and W1211. All three may be taken without preparation in statistics. All three cover roughly the same concepts, but differ substantially in the mathematical maturity that is assumed and in the sophistication of the examples.

STAT W1001 is for students who have no more than the most basic algebra, and may be of interest to students in non-mathematical disciplines seeking to satisfy the Quantitative and Deductive Reasoning requirement. STAT W1111 is for students who have mastered basic algebra; practice is emphasized over mathematical theory. STAT W1211 is for students with competence in differential and integral calculus and emphasizes theory over practice.

STAT W1211 or W1111 may be substituted for ECON BC2411 in satisfaction of the major requirements in Economics. STAT W1211 is required for the major in Mathematics-Statistics, Economics-Statistics, and Statistics, and the for the concentration in Statistics. STAT W1001 and W1111 may be applied to the major requirement in Political Science-Statistics. Students that declared their major in Psychology prior to the 2008-2009 academic year may satisfy their major requirements with STAT W1111 or W1211 in lieu of PSYC BC1101.

STAT W2110 follows on the material of the three introductory courses, and is designed for students interested in developing practical skills. Applications of statistics to current issues in the sciences and social sciences are emphasized.
