Online Master's in Data Science for Jobs in Illinois

Home to 34 Fortune 500 companies and dozens of innovative startups, Illinois is among the top states in the U.S. for qualified data scientists. According to Crain’s Chicago Business, the city of Chicago is “emerging as a data-science hub” and is the “top market behind only Silicon Valley and perhaps Seattle and New York.” Outside of the city, corporate juggernauts such as Caterpillar Inc. in Peoria and Deere & Company in Moline are actively implementing data science into every aspect of their business, providing ample career opportunities for qualified professionals throughout the state.

Allstate Insurance headquartered in Northbrook, is just one major company using data science to reduce costs and create innovative solutions. In recent years, the company has detected hundreds of cases of insurance fraud through massive data analysis using the software platforms Hadoop and Tableau, according to Fortune. Additionally, through predictive algorithms based on historical data, the company has cut down on unnecessary homeowner inspections by 20%, saving some $3 million.

In the public sector, the city of Chicago has employed a data science team to improve the efficiency of a number of city-run operations. Among the goals the city hopes to accomplish through the use of data science in the coming years:

  • Make the city’s databases accessible to the public
  • Create a suite of business intelligence tools to connect the city’s users
  • Deliver options for enterprise data management

As the field of data science grows at unprecedented rates, professionals in Illinois are pursuing a master’s degree in data science to learn the advanced skills sought after by global powerhouses and cutting-edge startups alike. To gain admission, students must meet highly selective requirements, with schools considering applicants’ past education, work history, and competency in a variety of areas related to the field.

Undergraduate Degree and Master’s Prerequisite Courses

To earn admission to graduate schools with data science programs, students would typically be expected to meet the following undergraduate requirements:

  • Applicants must earn a 3.0 GPA or higher during undergraduate studies
  • Applicants must possess a bachelor’s degree in a field such as computer science, engineering, applied math, or statistics
  • Applicants must complete prerequisite courses, which typically include the following:
    • Statistics
    • Calculus I & II
    • Programming
    • Linear algebra

Applicants must have working knowledge of fundamental concepts in the following areas:

  • Data structures
  • Linear algebra
  • Algorithms and analysis of algorithms

How to Succeed on the Quantitative Reasoning Sections of the GRE/GMAT Exams

Applicants can position themselves for top consideration into master’s degree programs by scoring in the top 15 percent of the quantitative section of the GRE or GMAT. Programs may also evaluate applicants’ scores in the Verbal and Writing sections, which can show strong communication skills.

GRE – The Graduate Record Exam (GRE) revised general test quantitative reasoning section evaluates the following:

  • Algebraic topics such as expressions, linear equations, quadratic equations, graphing, and functions
  • Data analysis topics such as statistics, interquartile range, permutations, probabilities, graphs, and standard deviation
  • Geometry topics including the properties of triangles, quadrilaterals, circles, polygons, and the Pythagorean theorem
  • Arithmetic topics such as integers, roots, exponents, and factorization

To prepare for the GRE, students may take two sample tests by downloading a free program through Educational Testing Service (ETS). Additionally, students may sign up with the Princeton Review to take a practice exam.

GMAT – Consisting of 37 questions, the quantitative section of the Graduate Management Admissions Test (GMAT) is designed to evaluate students’ data analytics skills, particularly in problem solving and data efficiency. To prepare for the GMAT, students may take practice exams through Veritas Prep and the Princeton Review.

Relevant Personal and Work Experience for Admissions

Admissions departments may give top consideration to applicants who have demonstrated exceptional quantitative and analytical reasoning capabilities and strong communications skills through work experience. Relevant skills would include:

  • Database administration proficiency
  • Total relevant work experience (five years is preferred)
  • Data mining skills
  • Programming proficiency in languages such as JAVA, C++, and Python
  • Coding skills
  • Hacking skills

Just a few examples of qualifying work experience and employers in Illinois might include:

  • Statistical analysis at The Boeing Company
  • Cyber security at Walgreens
  • Working in data management at Mondelēz International

Bridge Courses and Massive Online Open Courses (MOOCs) for Applicants Who Do Not Meet Admission Criteria

To obtain any outstanding qualifications required for admission to a master’s program in data science, students may opt to proactively enroll in relevant MOOCs prior to applying. Those that have already gained acceptance into a graduate program based on other merits may participate in bridge courses as a precursor to graduate-level coursework:

Bridge Courses allow students to fill gaps in functional knowledge in the following fundamental areas:

  • Programming in languages such as JAVA, Python, and C++
  • Data structures
  • Analysis of algorithms
  • Linear algebra

Bridge courses are made available to students that have met all enrollment criteria and that have been accepted into the graduate program, but that just need to gain proficiency in a particular area before transitioning to master’s-level coursework. Bridge courses are typically completed in about 15 weeks time.

MOOCs – Massive Open Online Courses – allow students to develop diverse new skill sets through a blend of online data sets, filmed lectures, and student-professor communication. MOOCs are offered through industry organizations and are completely separate from graduate school.
