Statistical Data Science Major

The new Bachelor of Science (BS) in Statistical Data Science will give you a strong foundation in statistics, programming, and mathematics, as well as the flexibility to tailor your degree to your interests.

Majors take 36 credits of coursework, where they learn core skills and how to apply those skills to a domain area of their choice. They also take advantage of research and internship opportunities.

Program Overview

Statistical data science majors are trained in basic and advanced data analysis ranging from introductory statistics and calculus to statistical machine learning and linear algebra. Students learn how to use data ethically; the importance and effectiveness of visualization in communicating results; and programming skills in both R and Python. They also dive deep into an area of interest that forms the basis of their culminating capstone project.

To complete the BS in Statistical Data Science, students are required to only take one sequence of lab courses, along with an additional science course that does not need to be a lab course. This differs from most BS degrees in the College of Liberal Arts and Sciences, which require two sequences of lab courses along with an additional lab course.

Graduates of the major can expect to find work in almost all occupational realms. Alumni are prepared to serve in a number of roles in which they will operate and design analytical systems, prepare data, coordinate analysis, visualize output, and support data-driven decision making.

Major Requirements

Admitted students are required to take 36 major credits that include courses in five core areas; a nine-credit domain sequence; an introduction to data science course; and a capstone course. Students can meet the Writing in the Major requirement in a statistics W course or a capstone W course. Majors must maintain a 3.2 cumulative GPA.

The five core areas provide you with the foundation necessary to work as a data scientist in any field or professional area. They include:

  • Computer programming and data management.
  • Basic data analysis.
  • Advanced analysis.
  • Data visualization.
  • Data ethics.

A domain sequence is a sequence of courses designed to help you apply core data science skills to a professional area that interests you most. The statistical data science major domain sequences include:

  • Advanced Statistics.
  • American Political Representation.
  • Biological Data Science.
  • Financial Analysis.
  • Marine Science.
  • Population Dynamics.

Domain Descriptions

Advanced Statistics

Faculty Advisors: Elizabeth Schifano, Department of Statistics and Haim Bar, Department of Statistics

The Advanced Statistics domain provides students with more advanced statistical and data scientific tools applicable to a wide range of disciplines.  Students in Advanced Statistics take one additional methodological course to more fully appreciate data-driven decision making in the context of statistical inference, whereas the remaining two courses have more applied emphasis in terms of experimental design, biostatistics, modeling of dependent (time-series and/or spatial) data, and/or internship experience relating to data science.  Graduates from Advanced Statistics will be well-prepared to tackle a diverse range of a data types and analytic problems in the realms of business and marketing, sports analytics, medicine and public health, government, and beyond.

American Political Representation
Faculty Advisor: Jason Byers, Department of Political Science

Political representation is at the core of democratic governance. It includes the multifaceted interests, incentives, opinions, and relationships among the public, politicians, and campaigns central to elections and policies. In the United States, it is also structured by the layered and complicated institutions of the federal, state, and local governments.   

The study of American political representation necessitates extensive theoretical and contextual skills. Contemporary American politics students also need empirical training. Understanding hypothesis development, research design, data collection, coding, analysis, and presentation is essential to understanding and contributing to knowledge about American politics. This domain within the Applied Data Analysis Major provides the insights and skills necessary for students to address some of the most important questions confronting the United States.

Biological Data Science

Faculty Advisors: Jonathan Klassen, Department of Molecular and Cell Biology and Yaowu Yuan, Department of Ecology and Evolutionary Biology

Recent technological advances have made large datasets widespread throughout the biological sciences. Although the types of input data differ, their analysis shares a common logic based on the scientific method and frequently uses an overlapping suite of analytic and visualization tools. This is reflected by the many computational courses available in the Biological Data Science Domain, which include course subsets centered around a particular data and analysis types that can be readily intermixed and combined with independent research projects. Graduates from the Biological Data Science will be well-prepared to analyze similar datasets while supporting research in the biotechnology and pharmaceutical industries, as well as in the academic, government, and not-for-profit sectors.

Financial Analysis
Faculty Advisor: Min Seong Kim, Department of Economics

The Financial Analysis Domain provides students with essential skills and knowledge in financial economics and relevant quantitative analysis methods. Students are required to complete three out of the following four courses:

ECON 3313 Elementary Economic Forecasting: This course focuses on economic forecasting for macroeconomics and financial economics. Students learn econometric analysis techniques for time-series data to forecast and predict economic trends and financial market behaviors.

ECON 3315 Financial Econometrics: This course is an Introduction to the mathematical foundations of finance. Topics covered include theoretical reasoning, modeling, useful simplifying approximations, and computing. Students also learn to write basic programs in R.

ECON 3413 Financial Economics: This course explores basic principles used in investment decisions and their applications to pricing financial assets and portfolio management. Students learns asset pricing models including the Capital Asset Pricing Model and Arbitrage Pricing Theory. The courses also covers fixed-income securities, options and futures.

ECON 4323 Convex Optimization with Python: This course introduces methods of convex optimization, including linear, quadratic, and general constrained and unconstrained problems. Students learn how to solve optimization problems in economics and finance applications using Python.


By completing the Financial Analysis Domain, students develop a solid foundation in financial theory, quantitative methods, and data analysis techniques essential for careers in finance, investment banking, and financial consulting.

Marine Science
Faculty Advisor: Heidi Dierssen, Marine Sciences

(Coming Soon)

Population Dynamics
Faculty Advisor: Jeremy Pais, Department of Sociology

Population Dynamics examines society through demographic processes. The curriculum provides an overview of the theory, data, and methods used by demographers and other population scientists—like sociologists, public health researchers, labor economists, environmentalists, epidemiologists, and social geographers—to understand how population change through fertility, mortality, and migration impacts our societies. Knowledge of ongoing population dynamics is critical to promoting healthy social institutions that shape everyday living, from doctor’s appointments, consumer products, and classroom experiences to dating and even your vacations or a peaceful walk in the woods.  


The coursework for this domain will introduce students to the diversity of data sources used by population scientists and the modern methods used to analyze these data. Data exposure will cover a gambit from traditional sources like Census data and nationally representative longitudinal surveys to more modern applications of administrative data, network data, spatially referenced data, and computationally intensive unstructured data from social media platforms.

Questions to consider when choosing a domain:


Would you like to apply data science to a specific area or sector, or would you prefer to be as broad as possible?

What classes have you taken and enjoyed? Is there a domain in those areas? If not, is there one that seems related to those areas?

What are you passionate about and how do you want to apply that in a career?

Additional Degree Options

Double Majors, Dual Degrees, and Minors

Students can enrich their college experience by adding a double major, a dual degree, and/or a minor.

Statistical data science majors who wish to add another major in the College of Liberal Arts and Sciences (CLAS), a major outside of CLAS, or a minor should consult with the statistics staff advisor about which option might work best based on their career goals, interests, and graduation timeline.

Students interested in a major or minor outside of statistics should also meet with that department to get a full understanding of the requirements for the major or minor, and the timeline for graduation.

Students interested in adding statistical data science as a double major can meet with the statistics staff advisor to discuss the major, requirements, and timeline for graduation.

Honors Program

Highly motivated students seeking a more intensive workload have the option of enrolling in the UConn Honors Program, which involves completing challenging coursework and an honors thesis. Learn more about the program.
