(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.

Mathematics/Economics double majors may substitute ECON 385 for STAT 316 as one of the core courses.
Or permission of instructor
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.
