Online Master's in Data Science for Jobs in Illinois

Home to 36 Fortune 500 companies and countless startups, Illinois is among the top states in the U.S. when it comes to jobs for qualified data scientists. With teams of analysts turning the terabytes of data that come spiraling out of financial services firms and investment banks, healthcare providers, and every other kind of major industry into actionable business intelligence, Crain’s Chicago Business wasn’t just bragging when it referred to Chicago as the top big data hub in the U.S. behind only Silicon Valley, Seattle and New York.

From its headquarters in Northbrook, Allstate Insurance has been marshalling the power of big data to reduce costs and create innovative solutions. According to Fortune, in recent years, the company identified  hundreds of cases of insurance fraud through deep claims history analyses, and put predictive algorithms to work to cut down on unnecessary home inspections, reducing the number by 20% and saving the company some $3 million.

And outside the city, industrial juggernauts like Caterpillar Inc. in Deerfield and Deere & Company in Moline are turning data scientists loose on every aspect of their businesses, providing all kinds of opportunities for qualified analysts who might be more interested in how big data plays a role in everything from industrial supply chain management to agriculture.

In the public sector, the city of Chicago has put a team of data scientists to work to improve the efficiency of a number of city-run operations, and is passing on the benefits of what they learn. Municipal government has plans to make the city’s databases accessible to the public and create a suite of business intelligence tools accessible to small businesses, while also offering solutions for enterprise data management.

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

If you want to land on the top of the stack when the selection committee is reviewing applications, then there is no substitute for 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 demonstrate the kind of strong communication skills that are critical in conveying the results of data science efforts.

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, you 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 also tend to give extra consideration to applicants who have demonstrated exceptional quantitative and analytical reasoning capabilities and strong communications skills through work experience. Data science is a rapidly evolving field, and sometimes the most cutting-edge insights come directly from the coal face rather than cold academic assessments. 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

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

Using a Data Science Bootcamp in Chicago or Online to Prepare for a Masters Degree or to Transition Straight Into a Job

Bootcamps are hardcore, compressed, real-world data science training that happens in a short timespan of between one and nine months. They usually focus on working with real-world data, and use tools and techniques that are actively in play in the industry, with less time spent addressing the theoretical world of data analysis and more focus on results.

As a less expensive and more focused option than other courses of preparation, bootcamps have typically been offered by private training companies. They’ve become so popular, however, that many big-name universities are getting in on the trend, including Chicago’s Northwestern University.

At the Northwestern Data Science and Visualization Bootcamp, students get an immersive 24 week course, conducted on evenings and weekends, that puts them through essential aspects of data science including:

  • Python and Javascript programming
  • Data visualization with Tableau, HTML, and CSS
  • Data storage in SQL and Hadoop stores

It’s all done with data sets drawn from industries like finance, healthcare, and government to give you real experience in the challenges of real-world quantitative analysis. You have the support of a comprehensive tutor network and one-to-one career coaching and portfolio and resume reviews to help you land a job in the field if going on to a master’s is not in your immediate plans.

Other bootcamps cater to more advanced users, but you can get into Northwestern’s with only a phone interview and a critical-thinking and problem-solving assessment if you are 18 and have at least a GED. It’s a solid course in the fundamentals to get your skills ramped up for a data science master’s degree, or to make the transition directly into a data science job in the field.

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

Another route to beefing up your skills before enrolling is to proactively enroll in relevant MOOCs, or to participate in bridge courses offered by the school itself as a precursor to graduate-level coursework.

Bridge courses are either current or specially designed college classes that can help you fill gaps in functional knowledge that the master’s program will demand. They usually cover topics such as:

  • 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 who 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, although many are backed by large universities and offer identical coursework to some of their most popular classes. MOOCs are a good choice for self-motivated, self-studiers who want to pick and choose their coursework before applying to master’s programs.
