Purpose Statement
Because the amount of global information collected is increasing rapidly due to technological advances, businesses and organizations that can utilize that information stand to benefit. Those organizations need people with the unique skillsets to store, access, and manipulate large sets of data; visualize and model relationships present; and draw actionable inference to make data-informed decisions.
Our students learn the fundamentals of computer science to facilitate the automation of tedious tasks, data storage, and algorithmic problem solving. They also learn statistical science foundations to inform data collection methods, model linear and non-linear relationships, and create predictive models. Students will be exposed to real data drawn from many different fields and have hands-on experience in how data insights are made.
Students with a Bachelor of Science degree in data science could pursue jobs as a business analyst, actuary, and data scientist for both public and private organizations in a diverse set of fields such as research, engineering, finance, marketing and public health.
Student Learning Outcomes
