Modern statistics is an exciting subject that affects most aspects of modern living. It has been developed to deal rationally and objectively with the uncertainty that accompanies variation in phenomena as highly complex as the interplay of the many factors that affect our environment. It derives vitality in coping with practical problems arising in all fields of scientific activity, including the social, business, biological, agricultural, medical, natural, and engineering sciences. Investigators' efforts to learn about a specific phenomenon, be it the response of a patient to a certain medical treatment or the effectiveness of a particular instructional program on a student's learning, are impacted by the presence of natural variation. The field of statistics is concerned with valid and efficient ways to learn more about these phenomena in the presence of such variation. It is an inductive science in which information is extracted from sample data in order to draw inferences. This process most often involves planning experiments or designing studies to ensure that valid answers to questions are obtained from the sample.

To declare the statistics major, student should set up an appointment with a statistics major advisor prior to attaining senior standing (86 credits). 

Prospective majors are strongly recommended to have completed the following classes before declaring the major:

  • MATH 221 Calculus and Analytic Geometry 1
  • MATH 222 Calculus and Analytic Geometry 2 
  • MATH 234 Calculus--Functions of Several Variables 
  •  STAT 302 Accelerated Introduction to Statistical Methods

  • Earn a 3.500 overall university GPA
  • Earn a 3.500 GPA for all STAT courses, and all courses accepted in the major
  • Complete one of the following:
    • Two courses, taken for Honors, with individual grades of B or better, from Linear Statistical Models, Mathematical Statistics, or Statistics Electives other than STAT 699 Directed Study, or
    • Complete an additional course worth 3 credits from the Statistics Electives list (for a total of 12 statistics electives)

University Degree Requirements 

Total Degree To receive a bachelor's degree from UW–Madison, students must earn a minimum of 120 degree credits. The requirements for some programs may exceed 120 degree credits. Students should consult with their college or department advisor for information on specific credit requirements.
Residency Degree candidates are required to earn a minimum of 30 credits in residence at UW–Madison. "In residence" means on the UW–Madison campus with an undergraduate degree classification. “In residence” credit also includes UW–Madison courses offered in distance or online formats and credits earned in UW–Madison Study Abroad/Study Away programs.
Quality of Work Undergraduate students must maintain the minimum grade point average specified by the school, college, or academic program to remain in good academic standing. Students whose academic performance drops below these minimum thresholds will be placed on academic probation.
  1. Students will be able to frame a scientific question with the appropriate mode of data analysis, to analyze such data correctly, and to summarize and interpret the results in a useful manner. They will master a number of key statistical techniques, certainly including significance testing, goodness-of-fit testing, and regression analysis, which are common tools in analyzing data. This will include a careful checking of assumptions that underlie the techniques.
  2. Students will be able to design experiments/studies —  in conjunction with scientists proposing the study — that will lead in an efficient manner to the collection of data that can be properly analyzed. They will be able to design studies with multiple factors taking variable reduction techniques into account. They will also be able to interpret and critique designs they encounter in analyzing data.
  3. Students will be able to use tools from mathematical statistics and probability to assess the quality of point estimators, confidence intervals, and hypothesis tests. They will also be able to demonstrate the skills to connect methods of application to their theoretical underpinnings.
  4. Students will be able to use a statistical language (with emphasis on R) to manipulate data and perform exploratory data analysis using basic statistical methods. They will be able to write structured R programs using conditional expressions, loops, and functions and to use regular expressions to extract data from text and make high-level visualizations.
  5. Students will be able to evaluate critically articles that use statistical argumentation. They will be able to assess whether or not the statistical arguments have been developed properly and the conclusions are reliable. If the arguments are not properly developed, they will be able to provide specific evidence for this.

So what can you do with a statistics major after you graduate?

Well-trained statisticians are in strong demand and have excellent employment prospects. Statisticians work in industry and business, in government, and in universities and other research institutions.

In most cases an undergraduate major in statistics can find employment as a quantitative analyst or other “generalist” position. A number of our graduates have been successful following this path. However, in most cases, positions aimed at “professional statisticians” require a master's (or Ph.D.) degree. As a professional statistician, typical employment in industry might be as a statistical consultant to biologists, engineers, and/or other scientists in a research and development branch of a large company.

The single, best place to look for statistics jobs is the American Statistical Association Career Center. Consult with a statistics undergraduate advisor about the best fit for you.

Statistical training is seen as very desirable in many other areas (e.g., agricultural, biological, engineering, and social sciences, business, and economics) where the primary activity may not be statistics. In view of this, statistics may often be a strong choice for a second or additional major.
