Schneider, a Green Bay-based logistics and transportation company, uses the expertise and insights of data scientists in order to create new and innovative solutions. These data scientists develop algorithms and use quantitative reasoning to interpret statistics and analyze large data sets in order to help the company run at optimum efficiency. Rocket Industrial, a small business located in Wausau, uses master’s-educated data scientists to help optimize all areas of the company and increase revenue.
As companies compete for talent, the demand for master’s-prepared data scientists is increasing dramatically. According to Butch Works, an executive recruiting firm, the median annual salary for data scientists is $120,000. This is only fitting, considering that data scientists are helping companies solve complex problems and increase revenue.
Preparing for a Master’s Degree in Data Science
With so many high tech professionals eager to enter the field of data science, new graduate programs are being created to keep up with the growing demand. Students can prepare by making sure they meet the standards that are commonly upheld by graduate program admissions departments in terms of undergraduate education, work experience, functional proficiencies and high scores on entrance exams.
Undergraduate Degree and Master’s Prerequisite Courses
Due to the rigorous nature of these programs, graduate schools often maintain rigorous requirements for admission. In many cases, applicants must meet the following undergraduate requirements in order to gain entry into a data science graduate program:
- Completion of a bachelor’s degree in a quantitative field such as statistics, engineering, computer science, or mathematics
- An undergraduate GPA of at least 3.0.
- Undergraduate courses in related topics like statistics, calculus, and computer programming
- Three letters of recommendation from professional references or undergraduate faculty
Relevant Personal and Work Experience
Graduate admissions departments typically seek applicants who have significant professional experience in a field related to data science. Most programs require the following for entry into the program:
- At least five years of technical work experience
- Significant experience demonstrating proficient quantitative abilities such as data analysis, data management, computer programming, and other related skills
- Basic understanding of programming languages such as R, JAVA, C++, or Python
Graduate program applicants generally come from a professional background in database administration, math/statistics, network security, programming or data analytics.
How to Prepare for Success on the GMAT/GRE Exams
Applicants are expected to achieve high scores (at least in the 85th percentile) on the quantitative reasoning section of the GRE or GMAT exams in order to gain admission into a data science graduate program. Admissions departments also consider strong scores in the verbal and writing sections.
Students may take a free practice test online to prepare for the GRE or GMAT.
Bridging Gaps in Functional Knowledge Through Bridge Courses and MOOCs
Bridge Courses – Students that have been accepted into a graduate program in data science based on having met all enrollment criteria, but who may lack extensive professional experience or education in either fundamental math and statistics or programming, are often given the opportunity to take prerequisites before transitioning to master’s-level coursework. The need to fill gaps in functional knowledge in one or more areas before enrolling in a graduate program is common. These 15-weeek pre-master’s programs would be offered directly through the graduate school.
MOOCs (Massive Open Online Courses) – MOOCs provide aspiring data scientists with the chance to fill gaps in their knowledge through a blend of filmed lectures, online coursework, and student-professor communication. MOOCs are for prospective graduate students who wish to gain the necessary proficiencies before applying to a master’s program in data science and are available completely independent of graduate school.
Earning a Master’s Degree in Data Science in Wisconsin
Currently, there are residential graduate programs in data science available in Madison and Milwaukee. With most students seeking a more flexible program format, online options are even more widely used. A master’s program in data science consists of 30-32 credits and result in degrees with titles that include.
- Master of Science in Data Science (MSDS)
- Master of Information and Data Science (MIDS)
Curriculum and Core Coursework
Graduate students in data science programs will take courses covering the following topics:
- Analyzing data
- Applied machine learning
- Data visualization and communication
