The Departments of Mathematics and Computer Science have collaboratively mapped out a data science pathway for an IDM (interdepartmental major) between the two departments. This pathway makes it easier for you to identify courses relevant to a career in data science, and to plan and optimize your program of study accordingly.

Note that this IDM is intended for students interested in data science and its mathematical foundations, but not necessarily all the lower-level computational aspects. Depending on your interests, the other options include:

- The
**Data Science Concentration**within the COMPSCI BS major, which requires fewer courses on the mathematical and statistical foundations, but focuses more on the computational aspect and practical issues that arise in applying data science. - The IDM in
**STA+CS on Data Science**, which covers more topics on statistical data analysis.

### Prerequisites:

- COMPSCI 101L or 102 or 116 or equivalent
- MATH 111L and 112L or equivalent
- MATH 212 or 222 (but not 202)

These courses/credits will not count towards the 14 required courses below.

### From Computer Science:

- COMPSCI 201 - Data Structures and Algorithms
- One of COMPSCI 316 - Introduction to Databases or COMPSCI 516 - Data-Intensive Systems
**NOTE:***We are in the process of changing this requirement to COMPSCI 210 or COMPSCI 250, as COMPSCI 210 or 250 is now a prerequisite for COMPSCI 316. COMPSCI 316 will now be one of the elective choices. We will allow COMPSCI 316 or COMPSCI 210 or 250 for this requirement for anyone who matriculated before Fall 2022.*

- COMPSCI 330 - Design and Analysis of Algorithms
- One of COMPSCI 371 - Elements of Machine Learning, COMPSCI 370 - Intro. Artificial Intelligence, COMPSCI 570 - Artificial Intelligence, or COMPSCI 671 - Machine Learning
**NOTE:***COMPSCI 370 was renumbered from 270 in Fall 2019, and COMPSCI 671 from 571 in Spring 2019.*

- 3 Electives from the following (or others approved by the Director of Undergraduate Studies):
- COMPSCI 370, 371, 570, or 671
*(If not taken for the requirement above)* - COMPSCI 216 - Everything Data
- COMPSCI 230 - Discrete Math for CS
- COMPSCI 210 - Intro to Computer Systems or COMPSCI 250 - Computer Architecture
- COMPSCI 316 - Introduction to Databases
**NOTE:***COMPSCI 316 can be an elective if you take COMPSCI 210 or 250 in place of the COMPSCI 316 requirement above.*
