Data Science electives (9 units)

Data Science B.S. majors will have the opportunity to integrate the knowledge and skills acquired during their studies and think independently and creatively using the tools of the discipline during a capstone experience, which is an essential part of the undergraduate program. There are a variety of ways to complete the Capstone requirement, both within and outside Data Science. In particular, a number of the capstone experiences are shared across the B.S. and B.A. Data Science majors. 

Possible ways of satisfying the capstone requirement will include: 

1. Project-based classes where students work individually or in small groups to tackle real-life questions using data
2. A data science experience course that exposes students to the experiences of data scientists working in different fields and that facilitates a self-reflection on their own activities as data scientists
3. Individual research projects (which in some cases might be completed during a study abroad quarter, or might extend summer research carried out in the university)
4. Notation in science communication
