As a home to large telecom, health care and pharmaceutical companies, New Jersey has been at the forefront of innovation and technology for many years. In 2012, the New Jersey Big Data Alliance (NJBDA) was formed, with participants including top universities in the state that offer graduate programs in data science. Governor Chris Christie recognized this alliance in 2014 as New Jersey’s official Advanced Cyberinfrastructure Consortium. The NJBDA gives New Jersey’s colleges and universities the opportunity to work with government and industry to identify industry needs, as well as to isolate knowledge gaps among prospective students. This has allowed these schools to then tailor their programs to prepare students in a way that fits the needs of the state’s major employers.
Master’s-educated data scientists in New Jersey work for companies like Janssen Research and Development, LLC, the pharmaceutical arm of Johnson & Johnson in Raritan. Here, they mine data to help research and development professionals come up with new treatments for a variety of conditions and disorders, including diabetes, neurologic disorders, and immunologic disorders.
The telecommunications company, Verizon, in Basking Ridge, is also home to data scientists who use their problem solving and critical thinking skills along with the latest technology to analyze large and increasingly complex data assets. They contribute to investigating and fighting fraud in the company, identifying control gaps in processes, and analyzing root causes of problems.
Quest Diagnostics in Madison employs data scientists as well. These scientists extract and mine relevant data from biological laboratory samples. In an age where medical records are going exclusively electronic, data scientists at Quest Diagnostics also help coordinate sensitive, confidential electronic health data.

Preparing for Success on GRE/GMAT Exams
Prospective data science graduate students may prepare for these tests by studying and practicing key data science skills, with the objective of earning a score in the 85th percentile or better on the Quantitative sections of the exams.
GRE- The Graduate Record Exam (GRE) revised general test’s quantitative reasoning section assesses competencies in:
- Arithmetic areas including factorization, integers, roots and exponents
- Algebraic areas like functions algebraic expressions, linear equations, graphing and quadratic equations
- Geometric topics including the properties of triangles, circles, polygons, quadrilaterals, and the Pythagorean theorem
- Data analysis, with topics including standard deviation, statistics, tables, graphs, interquartile range, permutations, probabilities and Venn diagrams
Study aids for the GRE’s quantitative reasoning section include:
- The Princeton Review’s GRE Practice Exams
- Math Review by the Educational Testing Service (ETS)
- GRE Practice Exams and Prep Options through Kaplan Test Prep
The GRE is also offered in two subject test areas relevant to Data Science:
- Physics (Physics Test Practice Book):
- Classical mechanics
- Optics and waves
- Atomic physics
- Quantum mechanics
- Statistical mechanics
- Lab methods and specialized topics
- Special relativity
- Mathematics (Mathematics Test Practice Book):
- Discrete mathematics
- Introductory real analysis
- Probability, statistics and numerical analysis
GMAT – The Graduate Management Admission Test (GMAT)’s quantitative section assesses a student’s abilities in data analysis. In the Quantitative Section, which is one of the test’s four main sections, students must complete 37 questions on data analysis and problem solving in 75 minutes. Study aids to help bachelor’s-educated tech professionals prepare for the GMAT include:
Filling Gaps in Functional Knowledge Through MOOCs or Bridge Courses
Bridge Programs – Schools offering graduate programs in data science will often offer bridge courses to students that have met all admissions criteria and that have been accepted into the program, even though they may lack functional knowledge in one or more key areas. These pre-master’s courses are designed to bridge gaps in functional knowledge before students transition to graduate-level coursework. As an example, a student whose undergraduate degree is in computer science might need to take bridge courses in mathematics to prepare for graduate-level data science coursework. Schools usually offer bridge courses in two primary areas:
- Programming, teaching vital languages such as Python, R, C++ and Java
- Mathematics, offering coursework in areas including data structures, linear algebra and algorithm analysis
Massive Open Online Courses (MOOCs)—These courses offer online video lectures, interactive user forums, and problem sets, along with the support of professors and teaching assistants, and can be an indispensable tool in filling in knowledge gaps that prospective graduate students might have. Some MOOCs consist of open-access, public learning environments, while others are private and by invitation only. MOOCs provide a pathway to developing key proficiencies for prospective graduate students that wish to proactively prepare before applying to a master’s program in data science.
Earning a Master’s Degree in Data Science in New Jersey
Since Harvard Business Review declared data scientist to be “one of the sexiest jobs of the 21st century” in 2012, data science has emerged as one of the hottest fields of study at the graduate level for technically-minded students in New Jersey. Master’s programs in data science can be found all across the state, in cities including Jersey City, Trenton and New Brunswick, as well as online. Graduate degrees available in New Jersey that offer the proper credentials to future data scientists include, but are not limited to:
- Graduate Certificate in Data Mining
- Master of Business and Science Degree in Analytics- Discovery Informatics and Data Sciences
- Master of Information and Data Science
- Master of Science in Data Science
Total credit hours to compete a typical master’s program in data science range from 30 to 40. Some online schools offer part-time options, but typically require students to graduate within five years of starting the program.
Online graduate degree programs offer the same level of rigor and also range between 30 and 40 credits in length, but include the benefits of a flexible timeline and being accessible from anywhere in the world:
- Traditional – online master’s in data science programs that are typically completed in 18 months
- Part-time – students who opt to study part-time may complete the online program in approximately 32 months
- Accelerated – for those students who wish to work at an accelerated pace, most graduate programs in data science may be completed within a year
Graduate certificate programs usually take less time to complete – a year to 18 months – and range from 12 to 18 credits in length. These programs take the least amount of time, and may be accomplished in one to two semesters. Keep in mind, however, that a graduate certificate does not carry as much weight with employers as a master’s degree in data science. Most employers are looking for data scientists who possess graduate degrees.
Core Coursework, Internship and Emersion Experience
Courses that are typically found in master’s-level data science programs cover topics such as:
- Data analysis and decision modeling
- Statistical programming
- Data and database warehousing
- Data visualization

- Data mining
- Data law, ethics and privacy
- Predictive analytics
- Machine learning
- Experimental design
Additionally, unless a student already has three or more years of professional work experience in the field or is employed full-time in a paid data science position, a graduate internship is mandatory. This experience will provide the data science student with real-world work experience and allow prospective employers to ascertain the talents and strengths of potential employees. Many online data science graduate programs also require an internship, which would be offered at specific locations throughout New Jersey that partner with the major online programs.
Most graduate data science programs also require participation in an immersion experience. Students in both traditional and online data science degree programs would meet at a central location and collaborate on a specific set of problems, applying knowledge and skills that they have gained from their graduate program. Professors and professionals in the field of data science offer evaluations and assessments of outcomes.
