Master of Applied Sciences

MAS

The MAS degree emphasizes practical methods in statistics, focusing on applications and computational aspects. 

The goal of this degree is to enable students to start working as practicing statisticians in industry, government or academia immediately after graduation. This degree is offered via traditional resident instruction (on-campus), as well as online.

MAS Capstone Consulting

The MAS program culminates with the Capstone Consulting Module, STAA556. The course runs for six weeks (mid-May until the end of June). Enrollment in STAA556 requires successful completion of all previous 28 credits of the MAS program.

Students are assigned a genuine client-based project. Working in groups, students are expected to perform a principled and thorough statistical analysis of client data in response to some well-defined questions posed by a client. The results of the analysis are documented into a formal technical report which constitutes the main assignment of the course. 

The module provides an authentic opportunity for students to apply and consolidate techniques and tools acquired over the preceding MAS courses.

Clients who have participated in the Capstone Consulting course include Elanco (a division of Eli Lilly and Company), United States Department of Agriculture, ChildSafe (a local non-profit organization) and University of Colorado Health.
