Data Science Major
Data Science is the study of how to extract insight from data using statistics and computing. It is a major within Computing & Information.
Data Science is the study of how to extract useful information and insights from data using statistics, mathematics, and computer programming. Students learn how to collect, organize, and analyze datasets to answer real-world questions and solve practical problems. The major focuses on developing skills such as identifying patterns in information, building models to make predictions, testing whether conclusions are reliable, and communicating findings clearly to different audiences. Rather than studying data in the abstract, students work with actual datasets across many fields to understand how data analysis applies to concrete situations.
Students typically enter this major with an interest in both mathematics and computers, and often want to understand how data influences decision-making in organizations and society. The curriculum generally begins with foundational courses in statistics, programming, and mathematical reasoning. As students progress, they move toward more specialized topics in data handling and analysis, learning tools and methods used by working professionals. Most programs combine classroom instruction with hands-on projects where students apply their developing knowledge to real datasets, building experience before graduation.
Typical coursework
Course requirements vary by school, but a Data Science program commonly includes topics such as:
- Statistics
- Machine learning
- Data visualization
- Programming for data
- Databases
- Big data systems
Most programs also include general-education requirements and, in many fields, a capstone project, internship, or research experience.
Degree levels
Data Science is commonly offered at these levels:
- Bachelor's
- Master's
Availability differs by institution, and program names can vary (for example, a Bachelor of Arts versus a Bachelor of Science track).
Common career directions
Graduates with a Data Science background pursue a range of paths. Some roles related to this field of study include:
- Data scientist
- Data analyst
- Machine learning engineer
- Business intelligence analyst
Many careers require additional steps beyond the major — such as a graduate degree, a license, or a certification — and many graduates work in fields unrelated to their major. What you study is one factor among many in where your career goes.
