Statistics Major Requirements
Major in Statistics Requirements
Required Related Courses (3-7 units)
Required Major Courses (9 units)
The STAT courses for the Statistics major require prior training in calculus and linear algebra. Students do not have to complete all the related Math courses before starting the main Statistics course sequence (STAT 320); however, courses in the main Statistics sequence do require some of these Math courses as either prerequisites or co-requisites. See the Full Course List on our website or the Undergraduate Course Catalog for course-specific requirements.
Related Math Courses (3-7 units)
Pre/Co-requisites for the 300 level courses in the Statistics Major
- MATH 220-1, MATH 220-2 or MATH 218-1, MATH 218-2, MATH 218-3
- MATH 226*
- MATH 230-1, MATH 230-2*, and MATH 240-0, or one of the following equivalent series: MATH 228-1, MATH 228-2, and MATH 240-0, or the MATH 281 series - Accelerated Mathematics for ISP, or the MATH 285 series - Accelerated Mathematics for MMSS, or the MATH 290 series - MENU: Linear Algebra and Multivariable Calculus, or the MATH 291 series - MENU: Intensive Linear Algebra and Multivariable Calculus, or ES_APPM 252-1, ES_APPM 252-2, and GEN_ENG 205-1
See https://www.math.northwestern.edu/undergraduate/first-year-focus/index.html for the Math department’s detailed information about placement in calculus and non-calculus courses.
*Statistics majors/minors are not permitted to take STAT 228/MATH 235-0 as a replacement for MATH 226 and MATH 230-2. If a student is a Statistics major and a Data Science Major, they will follow the related Math course requirements for the Statistics major instead of the Data Science Major; see https://statistics.northwestern.edu/undergraduate/data_science_major/ds_major_close_major_minor.html#statmdsm
Please note the Department of Mathematics made changes to their calculus courses that started in the 2019-2020 academic year. You can access a document with the related courses prior to 2019-2020 here.
Major Course Requirements (9 courses)
Introductory Statistics course (1 unit)
1 of the following courses:
- STAT 202-0 Introduction to Statistics and Data Science
- STAT 210-0 Introduction to Probability and Statistics
- STAT 232-0 Applied Statistics
Note: Most students with a score of 4 or a 5 on the AP Statistics exam will have received credit for either STAT 202-0 or STAT 210-0 and thus do not need to take an introductory Statistics course. Please review the credit table corresponding to the year in which you completed the AP Statistics exam to see how your credit will apply: https://weinberg.northwestern.edu/undergraduate/first-year-transfer/first-year/placement-and-credit/ap-and-ib-exams/index.html
STAT 202 includes a brief introduction to the statistical programming language R, while STAT 210 instead spends more time covering the basic elements of mathematical probability.
Foundational courses (4 units)
- STAT 320-1 Statistical Theory & Methods 1* (Co-requisites: STAT 202-0 or STAT 210-0, MATH 226-0, and MATH 230-2)
- STAT 320-2 Statistical Theory & Methods 2 (Prerequisite: STAT 320-1 or equivalent; see* below)
- STAT 320-3 Statistical Theory & Methods 3 (Prerequisites: STAT 320-2, MATH 240-0)
- STAT 350-0 Regression Analysis (Prerequisite or co-requisite: STAT 320-1 or equivalent see* below)
*NOTE: Students may not receive credit for both STAT 320-1 and any of the following: STAT 383-0, MATH 310-1, MATH 311-1, MATH 314-0, MATH 385-0, ELEC_ENG 302-0, or IEMS 202-0. Although in some cases not ideal, any of these seven courses can be used to satisfy the STAT 320-1 requirement for the Statistics Major or Minor (subject to the WCAS “no double counting” rule, see https://weinberg.northwestern.edu/undergraduate/degree/double-counting-faq.html). If you take a STAT 320-1 equivalent course, please see this pdf for information on the topics that may not be covered in the equivalent course but that you will be required to understand for STAT 320-2. Students who have not taken STAT 320-1 are responsible for independently learning these topics prior to starting STAT 320-2.
Standard methods course (1 unit)
1 of the following courses:
- STAT 348-0 Applied Multivariate Analysis (Prerequisites: STAT 320-2, MATH 240-0, and STAT 350-0)
- STAT 351-0 Design and Analysis of Experiments (Prerequisite: STAT 320-1 or MATH 310-1 or MATH 314)
- STAT 354-0 Applied Time Series Modeling (Prerequisites: STAT 320-1, Co-requisite: STAT 350-0)
- (or STAT 325-0 Survey Sampling, if taken in 2020-2021 or earlier)
STAT elective courses (3 units)
3 additional 300-level elective courses offered by the department and approved for the Statistics major – Note: MATH 310-2, IEMS 315-0, IEMS 351-0, IEMS 365-0, or IEMS 373-0 may substitute for 1 of the 3 STAT 300-level elective courses. Only 1 substitution is permitted.
See Electives Approved for the Statistics Major for the list of approved STAT courses.
Additional Math and Computing Recommendation for Students Considering a PhD
Students who are considering eventually obtaining a PhD in statistics should take additional mathematics coursework. Since modern statistical work relies heavily on computers, students are also encouraged to develop skills in programming and the use of advanced statistical software. The Director of Undergraduate Studies and other members of the faculty can recommend courses that are likely to be most valuable for those considering graduate studies.
Statistics Major Requirements for Closely Related Majors
The department has identified the following as closely related major/minor programs that require modification to the major requirements for students to do both programs:
- Statistics Major + Mathematical Methods for the Social Sciences (MMSS) major
- Statistics Major + Data Science Major
- Statistics Major + Data Science Minor
See Statistics + Closely Related Major/Minor for more information about which requirements are modified when doing these major/minors together.
Honors in Statistics
Honors in Statistics gives outstanding senior Statistics majors an opportunity to design and carry out a research project of their choice, which forms the basis of the Honors Thesis. Read more
