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.

Applying to the Major

Students interested in the BS in Statistical Data Science must apply for admission to the program. Applicants must meet the prerequisite course requirements below.

Spring 2025 Deadline: Friday, Sept. 20, 2024
Fall 2025 Deadline: Friday, Feb. 14, 2025

The application for the major is open year-round. We will notify students of their acceptance to the major prior to course registration.


Prerequisite Course Requirements

In order to apply to the BS in Statistical Data Science, students must have:

  • A GPA of 3.2 or higher in the following classes: MATH 1132Q, STAT 1000Q/1100Q, and an introductory programming course (CSE 1010, CSE 1729, or STAT 2255).
  • Completed at least 24 credits, 15 of which must be at UConn, with a cumulative GPA of 3.2 or higher.

Students not yet eligible to apply may declare a pre-statistical data science major. Pre-majors must formally apply to the BS in Statistical Data Science when they are eligible. They will be assigned an advisor in the meantime who will help them navigate course selections to work toward the statistical data science major.

Major Course Requirements

Students admitted to the statistical data science major are required to take a total of 36 credits consisting of:

  • One or more courses in each of the Core Area Requirements (full list below).
  • A nine-credit domain sequence (full list below).
  • STAT 3255. Introduction to Data Science.
  • STAT 4915. Data Science in Action (capstone) and STAT 4916W (information literacy competency and writing in the major requirement).

Note: Students completing a Biological Data Science domain may take any of the following to meet the capstone and W requirement: (i) STAT 4915 / STAT4916W, (ii) EEB 4896W, or (iii) MCB 4897W. Credits in EEB 4896W cannot simultaneously count toward both an Honors thesis in EEB and a Data Science capstone.

Core Area Requirements

  • Programming and Data Management: STAT 2255 (one course, 3 credits).
  • Basic Data Analysis: STAT 3025Q or STAT 3375Q* or MATH 3160; and STAT 3215Q (two courses, 6 credits).
  • Data Ethics: PHIL 3202 (one course, 3 credits).
  • Data Visualization: STAT 3675Q* or GEOG 3510 or EEB 4100** (one course, 3-4 credits).
  • Advanced Analysis: MATH 2210Q and STAT 4255 (two courses, 6 credits).


Please note:

  • *Students completing a statistics domain must take STAT 3375Q and STAT 3675Q to meet these requirements.
  • **EEB 4100 is recommended for students completing the Biological Data Science domain.

Domain Sequences and Requirements

Students must take at least three courses (9 credits) from one of the following domain areas. After completing the skill and domain area training, students will conduct a final research project which applies all the core data science skills to a practical problem in or related to their domain area.

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.

Academic Advising

Statistical data science majors work with both a staff advisor and faculty advisors throughout their undergraduate careers.

The staff advisor can help you with selecting classes, registration, general education requirements, and more.

Your faculty advisor can help you explore opportunities such as internships, research, and applying to graduate school. Learn more about the role of advising in the Department of Statistics.

Ready to Declare Your Major?

Students must apply for admission to the BS in Statistical Data Science program.

Current and prospective UConn students can indicate their intention to become a major by declaring as a pre-statistical data science major. Pre-majors must formally apply to the BS in Statistical Data Science program when they are eligible.

All eligible students may apply to the major. UConn students do not need to be pre-majors to apply. All applicants will be considered equally during application review.
