Data Science

Data Science Major

Data Science is the field of the twenty-first century.  It sits at the nexus of business, computer science, and statistics and as such, is a blending of the three fields. The goal of the data scientist is to perform analyses and make predictions using disparate sources of data. These analyses and predictions can help organizations and governments run more efficiently. The overarching goal of the field is the better use of information to make a difference in the world.

A major in Data Science prepares students to understand and enter this exciting field that unearths new knowledge on a daily basis. Technical skill coupled with a strong liberal arts education makes Loyola data science graduates especially desirable to employers. Typically, graduates assume professional responsibilities in positions such as data analyst or data scientist. Graduates are also prepared to continue their studies in data science or allied fields in graduate school.

Students majoring in data science will divide their major level courses among computer science, information systems, and statistics. The capstone course brings the major together in a culminating experience. In this course, students work with a client to apply their skills to a real problem.

The Data Science program leads to a Bachelor of Science (B.S.) degree. Faculty advisors help students coordinate their elective courses with their career plans. A minor in Data Science is also available.

Notes

EC 102 and EC 103 are recommended to fulfill the Social Science Core.

MA 151 may be substituted for MA 251 with permission of the program director.

CS 212 is a prerequisite for CS 312. MA 351 is a prerequisite for ST 461.

Up to two graduate-level Data Science courses may be taken as a DS Elective with approval from the program director.

CS 485 and ST 465 are offered every other year.

The Data Science major cannot be combined with a minor in Computer Science, Information Systems, or Statistics. Students may double major with these programs.

An internship as DS 499 may be taken for university credit, but does not count as an elective in the BS DS. It is not anticipated that this course would substitute for the capstone as the ethical component in the capstone is particularly important. This aspect would not necessarily be present in the internship. Instead it is expected that the internship experience may enhance the capstone experience for the student by providing the relationship from which the student can develop the capstone project.
