(Mathematics, Statistics, and Computer Science)

With the growing abundance of data gathered in nearly every field, statistical methods have become invaluable for transforming data into useful information. As a subject, statistics is interdisciplinary, spanning the sciences (natural and social), the humanities, and even the arts. Examples of areas of applications include economics, biology, health, education, actuarial sciences, and law. An increasing number of majors and concentrations require or recommend a statistics course.

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 the Statistics program.

Concentrators are encouraged to participate in an experiential learning opportunity, such as those available with the Center for Interdisciplinary Research.

MATH 282 and MATH 384 may count toward the concentration when a relevant topic is being taught and the student obtains the permission of the program director.

Experiential Learning Component (Optional)

Each concentrator is encouraged to participate in experientially based research or employment that takes statistical methods beyond the traditional classroom. This can occur on- or off-campus. Prior approval by the director of statistics program and a letter after the fact from a supervisor are required to earn credit. Excellent opportunities for experiential learning in statistics are available through academic internships (STAT 294), the mathematics practicum (MATH 390), and the Center for Interdisciplinary Research (CIR) (MSCS 389). As a CIR fellow, students can work during the academic year or summer with faculty on research from a variety of disciplines.

STAT 110, STAT 212, and ECON 263 all provide an introduction to statistics, and students should not take more than one; they can all serve as a prerequisite for further courses, although ECON 263 is geared toward majors in economics. STAT 214 is also an introductory course that assumes no background in statistics, but it can also be taken by students coming from STAT 110, ECON 263 or AP Statistics who would like a transition into the statistics concentration.

STAT 110: Principles of Statistics

This is an introductory course for the liberal arts. Students learn study design principles and develop statistical literacy and reasoning. They learn to describe distributions, assess if known distributions fit their data, estimate population values with confidence intervals, and assess statistical significance with hypothesis tests (e.g., chi-square, z-, and t-tests, ANOVA, correlation, and regression). In addition to lectures, there is a weekly computer lab. Not recommended for students who have completed a term of calculus. STAT 110, STAT 212, and ECON 263 all provide an introduction to statistics, and students should not take more than one; they all can serve as a prerequisite for further courses. Offered each semester. Counts toward environment studies major (social science emphasis) and exercise science major.

STAT 212: Statistics for the Sciences

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. Offered each semester. Enrollment limited for seniors. STAT 110, STAT 212, and ECON 263 all provide an introduction to statistics and students should not take more than one; they all can serve as a prerequisite for further courses. Counts toward environmental studies major (natural science and social science emphases), exercise science major, management studies concentration, and mathematical biology concentration.

This course engages students with the material in STAT 212 in greater depth and breadth. Topics such as bootstrapping and multiple regression will be introduced in addition to core material from STAT 212. No previous experiences with statistics is assumed; this course provides an introduction to statistics, but it can also be taken by students coming from STAT 110, ECON 263, or AP Statistics who would like a transition into the statistics concentration. Counts toward environmental studies major (social science emphasis), exercise science major, and mathematical biology concentration.

This course focuses on the use of statistics in a social science context. Students investigate three essential questions: How can one reliably measure something? How does one design valid research? How does one analyze research results? Topics include ANOVA designs (for example, one-way and two-way with interaction), data reduction methods, and principles of measurement. Interdisciplinary groups work together on case studies throughout the term. Offered alternate years.
Prerequisites: STAT 110, STAT 212, or STAT 214, or ECON 263, or equivalent preparation, or permission of the instructor.

STAT 272: Statistical Modeling

This course takes a case-study approach to the fitting and assessment of statistical models with application to real data.
