As a newly established field, the number of data scientists throughout the nation is particularly small, which makes the University of Massachusetts’ report that there will be 120,000 big data jobs by 2018 all the more significant.

The Worcester Polytechnic Institute named data scientist the hottest job in 2016. This is particularly true in two of Massachusetts’ largest economic sectors: healthcare and finance.

In the healthcare sector at Massachusetts General Hospital, data scientists can improve patient outcomes and operational efficiency by interpreting data and explaining large-scale analyses to management, who are then able to respond by developing new policies and protocols.

In the banking and finance sector, data scientists at places like John Hancock Financial or Liberty Mutual in Boston can increase revenues by developing large data models related to credit valuation adjustment, interest rates, and defaults.

Preparing to Earn a Master’s Degree in Data Science

Students preparing for a master’s degree program, and ultimately a career in data science can start by shaping their education during their undergraduate years in college. Education can be further augmented prior to beginning a master’s program. Developing relevant work experience is also critical.

On top of the proper education and professional experience, applicants can prepare to enroll in data science graduate programs by preparing for success on GRE and GMAT exams and filling gaps in functional knowledge through massive open online courses (MOOCs) or by completing bridge courses.

Undergraduate Degree and Master’s Prerequisite Courses

Data science graduate programs recruit students from academic backgrounds weighing heavily in quantitative reasoning:

  • Ideally students should have a bachelor’s degree in a quantitative field like statistics, applied math, computer science, or engineering
  • Academic history should demonstrate courses in disciplines like statistics, calculus I and II, programming languages, quantitative methods, and linear algebra
  • Applicants to graduate data science programs should have a minimum GPA of 3.0

Relevant Personal and Work Experience for Admissions

Many graduate programs only consider applicants who already have proven relevant professional experience:

  • Minimum of five years technical work experience, especially experience that demonstrates quantitative skills
  • Personal experience related to statistics, programming, database administration, coding, hacking, mathematics, and data mining

Some examples of qualifying work experience in Massachusetts could include:

  • Analyzing patient outcomes and medical data from either of Massachusetts’ two largest employers – Brigham & Women’s Hospital or Massachusetts General Hospital
  • Helping to code an analysis program for a financial institution like John Hancock Financial or Liberty Mutual
  • Providing cyber security for Boston University
  • Work with web analytics, marketing research, or demand indicators for a startup sponsored by the MassChallenge incubator

As most graduate applications require letters of recommendation, work experience can also serve to establish the contacts necessary to fulfill this important requirement.

How to Score Well on GRE and GMAT Exams

Scoring in the 85th percentile or above on one or both of these exams is a good way to stand out from the crowd and prove concrete skills. Admissions counselors pay particular attention to a student’s score in the quantitative reasoning sections. Prospective students can prepare for an exam by working problems from a number of study guides.

GRE The Graduate Record Exam (GRE) revised general test’s quantitative reasoning section covers the following topics:

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

Students can prepare for the quantitative reasoning section by reviewing Educational Testing Service’s (ETS) Math Review. The Princeton Review and Veritas Prep also provide free GRE resources.

The GRE is also offered in two relevant subject tests, covering the following topics:

Physics – physics test practice book

  • Classical mechanics
  • Electromagnetism
  • Optics and waves
  • Thermodynamics
  • Statistical mechanics
  • Quantum mechanics
  • Atomic physics
  • Special relativity
  • Lab methods and specialized topics

Mathematics – mathematics test practice book

  • Calculus
  • Algebra
  • Introductory real analysis
  • Discrete mathematics
  • Probability, statistics, and numerical analysis

GMAT – The Graduate Management Admissions Test’s (GMAT) quantitative section assesses students’ skills in data analysis. The quantitative portion is comprised of 37 questions to be completed in 75 minutes, and represents one-quarter of the entire GMAT. Questions from the quantitative portion pertain to data sufficiency and problem solving.

Practice GMAT practice exams can be found through the Princeton Review and Veritas Prep.

Filing Gaps in Functional Knowledge Through MOOCs and Bridge Courses

MOOCs can be an important source of supplemental information for students who want to gain introductory knowledge or hone their skills in a particular area of focus, such as programming prior to applying to a master’s program. MOOCs can be seen as a self-study approach to proactively preparing to enroll in a master’s program in data science.

Many graduate schools provide data science students with pre-master’s courses that fill in knowledge gaps in areas vital to success in graduate-level coursework. For example, students coming from an undergraduate background in engineering could attend bridge programs that relate to key programming languages. Bridge courses are available to students that have met all entrance requirements and have been accepted to a master’s program. These courses typically take about 15 weeks to complete before transitioning to graduate-level coursework.

Bridge programs can be a necessity for students who have an undergraduate degree in a field that is unrelated to quantitative reasoning.

Fundamental bridge programs:

  • Analysis of algorithms
  • Linear algebra
  • Data structures

Programming bridge programs:

  • JAVA
  • C++
  • Python
  • R
