OVERVIEW OF THE CONCENTRATION
At St. Olaf, students can combine their interests in statistics with any major and acquire a background that leads to graduate study and abundant career opportunities. To find out more about the statistics concentration, visit our website.
REQUIREMENTS FOR THE CONCENTRATION
Four courses: two required foundation courses in statistical modeling (plus prerequisites of Calculus I and Introductory Statistics), and two electives (as described below). Concentrators are encouraged to participate in an experiential learning opportunity, and to enroll in QWAC (Quantitative Work Across the Curriculum) modules when offered for courses they are taking.
1. Required Foundation
Statistics 272, Statistical Modeling
Statistics 316, Advanced Statistical Modeling
In addition, two courses are prerequisites for the required foundation: (1) Mathematics 120 or 121 (Calculus I), and (2) either AP Statistics, Statistics 110, Statistics 212, or Economics 263 (or permission of instructor)
Math-Economics double majors can substitute Economics 385 (Econometrics) for Statistics 316 (Advanced Statistical Modeling).

3. An Experiential Learning Component (Optional)
Each concentrator is encouraged to participate in experientially-based research experience or employment that takes statistical methods beyond the traditional classroom. This can occur on or off-campus. Prior approval by the director of Statistics and a letter after the fact from a supervisor are required to earn credit. Opportunities during the school year include independent study or consulting as a fellow in the Center for Interdisciplinary Research or during the summer as a member of an Interdisciplinary Research Team.
4. QWAC Course Credit (Optional)
Courses which offer a 0.25 course credit to add Quantitative Work Across the Curriculum (QWAC) credit should be taken by those concentrating in statistics when available.
Note: For students considering graduate school in statistics or a closely related field, the following courses are recommended: Calculus II, Multivariate Calculus, Linear Algebra, Real Analysis, Differential Equations, Modern Computational Mathematics.
Credit will not be given for more than one of Statistics 110, Statistics 212, or Statistics 263; credit will not be given for Statistics 110, Statistics 212 or Statistics 263 following Statistics 272.
This course is an introduction to basic concepts in statistics in the spirit of the liberal arts. Students will learn practical applications and the language and reasoning involved in analyzing behavioral and health science data. Topics include central tendency, dispersion, probability, random variables, binomial and normal distributions, estimation and hypothesis testing, contingency tables, analysis of variance, and correlation. Computer applications are integrated throughout. Not recommended for students who have successfully completed a term of calculus. Offered both semesters.
A first course in statistical methods for scientists, this course addresses issues for proposing/designing an experiment, as well as exploratory and inferential techniques for analyzing and modeling scientific data. Topics include probability models, exploratory graphics, descriptive techniques, statistical designs, hypothesis testing, confidence intervals, and simple/multiple regression. Prerequisite: Mathematics 120, 121, or equivalent, and an introductory science course. Offered both semesters.
This course emphasizes skills necessary to understand and analyze data. Topics include descriptive statistics, probability, random variables, sampling theory, estimation, classical hypothesis testing, and practical and theoretical understanding of simple and multiple regression analysis. Applications to economics and business problems use real data, realistic applications, and Minitab for Windows. Written reports link statistical theory and practice with communication of results. Prerequisite: Mathematics 120 or 121, and one of Economics 110-121, or consent of the instructor. Offered each semester.
This course takes a case-study approach to the fitting and assessment of statistical models with application to real data. Specific topics include two-sample comparisons, simple linear regression, multiple regression, model diagnostics, and logistic regression for binary response variables. Students focus on problem-solving tools, interpretation, mathematical models underlying analysis methods, and written statistical reports. Prerequisite: Statistics 110 or 212 or 263, or equivalent preparation or permission of instructor. Offered each semester.
This course explores methods of designing and analysing scientific experiments to address research questions, emphasizing statistical thinking and applications using real data as much as underlying mathematical structures and theory. Topics include completely randomized factorial designs, randomized block designs, split-plot designs, general linear models, and random effects models. Computer applications are integrated throughout. Prerequisite: Statistics 272 or permission of instructor. Offered during 2009-10 and alternate years.
The course focuses on investigating issues in global health from a quantitative, research- oriented perspective. Additional course material focuses on global public health issues and methods for analyzing health data. Students work on projects with researchers from the World Health Organization in Geneva, Switzerland, where they learn about the global burden of disease and how statisticians and epidemiologists can contribute to finding solutions. Students have the opportunity to tour the WHO facility, meet WHO researchers and learn about the work of statisticians and epidemiologists there. A visit to the International Cancer Research Centre (IARC) in Lyon, France provides an international perspective of issues associated with cancer research. Students also have the opportunity to explore the art and culture of Paris for a weekend while in France. Offered in 2010-11 and alternate Interims.
