Online Master's in Data Science for Jobs in Minnesota

The field of data science is experiencing major growth around the world and across the country, and Minnesota is no exception. Based in the Twin Cities, non-profit MinneAnalytics was founded to serve the data science and emerging technology community in the state. Today it has more than 17,000 regional members, drawn from every level and type of analytics profession.

Some of them work at companies like Target, one of the largest retail chains in the United States. Headquartered in Minneapolis, the company is famous in data science circles for a well-publicized story in which the ad-targeting algorithms deduced that shoppers were pregnant based strictly on shopping and purchase patterns, sometimes even before the shoppers themselves knew. The algorithm was so accurate that it was able to identify which trimester the customer was in. This translated into a measurable increase in profits for Target, and better access to the products the store’s customers preferred.

All of that points to the importance of a well-educated, highly-trained data science workforce, with analysts who both understand how to evaluate data and how to use their insights responsibly and effectively with respect to customer privacy concerns.

Whether in retail and logistics, healthcare and biotechnology, or banking and finance, master’s-educated data scientists are emerging as key players to increasing the bottom line in the data-driven business environment of the 21st century.

Preparing to Enroll in a Master’s Program in Data Science

As data science emerges as key to identifying new revenue streams, today’s employers prefer applicants with the proficiencies and leadership skills that come with earning a master’s degree in data science.

Preparing for a Masters Program or Employment Through Data Science Bootcamps in St. Paul or Online

As long as you are thinking ahead about how to prepare yourself to be accepted into a data science master’s program, think about this: enrolling in a data science bootcamp can give you both the experience and the skills you need to meet those qualifications, or to move straight into the job market in only a handful of months.

Bootcamps are a relatively new concept that mixes fast-paced instruction with reasonable costs and exposure to cutting-edge tools. You’ll find yourself crunching real-world data for the kind of project-driven problem-solving exercises modeled after what data scientists do every day. Overseen by veteran instructors, you learn with a cadre of other students in a practical, hands-on environment that builds a portfolio and real skills that admissions committees will view favorably.

Bootcamps were once the domain of independent providers, but big-name colleges have been getting in on the act, giving students access to even more academic and career resources. The University of Minnesota Data Visualization and Analytics Bootcamp is one of these. Available on campus in St. Paul or in a virtual classroom experience, this 24-week, part-time program operates at an introductory level with a focus on analysis and presentation skills. You’ll pick up skills like:

  • Social media tracking
  • Statistical analysis of big data
  • Building out dashboards and websites through tools like Tableau, HTML, and CSS
  • Programming data algorithms in Python and Javascript

Market demand drives the technologies that you are trained in, and you don’t need anything more than a GED and to have hit your 18th birthday to get in. Other types of bootcamps aim at mid-career professionals and higher skill levels, but this is exactly what you need to prepare for a master’s degree. Comprehensive career support is available as well if you choose to head right for a professional position after completing the camp.

Filling Gaps in Functional Knowledge with MOOCs and Bridge Courses
