In 2012, FCW reported that the city of Memphis, Tennessee was using big data to fight crime. After the Memphis Police Department launched the Blue CRUSH (Crime Reduction Utilizing Statistical History) initiative in conjunction with the University of Memphis, violent crime in the city was reduced. The initiative allows law enforcement officers to draw a polygon around areas of Memphis on a map and to receive predictive information on the likelihood of specific types of crime occurring in that area. This allows certain types of crime to be prevented.

Tennessee’s health researchers are also benefiting from big data. In 2014, the National Science Foundation supported a bioinformatics professor at the University of Tennessee working with a team from Washington State University on a $1.3 million grant for the Data Infrastructure Building Blocks (DIBBS) program. This program is designed to build upon and enhance the capacity of genomic databases in processing, managing and exchanging big data.
Clearly, Tennessee’s business and scientific professionals recognize the potential of big data. Bachelor’s-educated professionals with a background in quantitative knowledge and skills are pursuing graduate degrees in data science in Tennessee and online to become part of this revolution. Those who do find that Tennessee offers them many and varied career opportunities.
Information technology consulting and solutions firm Zycron, headquartered in Nashville, is one example of a Tennessee company hiring data scientists. Here, data scientists work with a variety of clients in communicating quantitative analysis to others clearly. They also collect new data, refine existing data, perform hypothesis testing, work on pattern classification, perform parameter estimation, and write and test software in many languages.
Healthcare business services and technologies companies such as Intermedix, which has facilities in Nashville, also use data scientists extensively. Data scientists at Intermedix build and enhance products for current and new clients to improve quality of health care as well as financial performance. They are involved in researching, designing, implementing and validating cutting-edge algorithms to analyze diverse sources of data and achieve targeted outcomes.
Genetic testing, a wave of the future, is also represented in Tennessee and employ data scientists. NextGxDx, a genetic testing company in Franklin, uses data scientists to develop new data products involved in genomic and genetic testing. These professionals work closely with marketing, sales, information technology and others in implementing, deploying and analyzing the company’s data assets. Their work is designed to make the testing process run much more efficiently and effectively.

- Programmer II at Health Trust in Brentwood
- Coder Analyst Specialist at Covenant Health Corporate in Knoxville
- Database Administrator at Experian in Franklin
Passing the GRE and GMAT Examinations
Passing graduate examinations, particularly the quantitative sections, is of great importance when applying to graduate data science degree programs. Admissions officers are typically looking for scores in the 85th percentile or above on the quantitative sections of the GRE or GMAT examinations.
GRE- the Graduate Record Exam (GRE) revised general exam’s quantitative reasoning section assesses a test-taker’s quantitative knowledge by posing:
- Algebraic questions on topics like algebraic expressions, graphing, linear and quadratic equations
- Arithmetic questions, on topics such as integers, roots and exponents, and factorization
- Geometric questions, on subjects including polygons, triangles, circles and quadrilaterals,
- Data analysis, including tables, graphs, probabilities, statistics, and standard deviation
Students may prepare for the GRE by studying:
- The Educational Testing Service (ETS)’s Math Review
- The Princeton Review’s GRE Practice Exams
- Kaplan Test Prep’s GRE Practice Exams
Subject area tests that help applicants to graduate data science degree programs are:
- Mathematics (Mathematics Test Practice Book):
- Discrete mathematics
- Introductory real analysis
- Probability, statistics and numerical analysis
- Physics (Physics Test Practice Book):
- Atomic physics
- Classical mechanics
- Lab methods and specialized topics
- Optics and waves
- Quantum mechanics
- Special relativity
- Statistical mechanics
The GMAT – The Graduate Management Admission Test includes a quantitative section that assesses an applicant’s knowledge of problem solving and data analysis by having them complete 37 questions in 75 minutes. Study aids for the GMAT may be found through:
Filling Gaps in Functional Knowledge By Means Of Bridge Courses or MOOCs
Bridge Courses – Some graduate data science degree programs will give applicants the opportunity to take bridge courses, if necessary. These courses, which are at the pre-master’s degree level, are designed to compensate for functional knowledge gaps an applicant may have. Many colleges and universities offer these courses online or in-person. Graduate data science degree programs usually offer bridge courses in subject areas such as:
- Computer programming languages, particularly C++, Java, Python, R and SAS
- Mathematics, particularly in topics like linear algebra, statistical methods and analysis of algorithms
Massive Open Online Courses (MOOCs)—These online courses provide another way applicants can fill in functional knowledge gaps, if they exist. They may be offered by online free or for a fee, and are given either by private invitation or via a public forum. MOOCs that may be of particular use to data science students include:
- Data mining
- Data analytics
- Machine learning
Earning a Master’s Degree in Data Science in Tennessee
While there are no traditional graduate data science degree programs in Tennessee, students there do have online graduate programs available to them. Related degrees that are available in Tennessee and online include:
- Master of Science in Data Science
- Master of Science in Predictive Analytics
- Master of Science in Data Management and Analysis
- Master of Science in Professional Science with a concentration in Informatics
These programs vary in length:
- Traditional master’s in data science degree programs run from 30 to 40 credits in length and are finished in 12 to 36 months, on a full- or part-time basis
- Online master’s in data science degree programs consist of about the same amount of credits, but give students more flexibility to take courses from anywhere, anytime. Often, they are completed more quickly than traditional graduate degree programs:
- 12 to 18 months for full-time students
- 24 to 36 months for part-time students Part-time students may earn a master’s degree in data science in two to three years
- 12 months for students of online accelerated programs
A graduate certificate in data science is another option for students. These programs range from 12 to 18 credits in length, and are completed in 12 to 18 months. Many employers, however, will not accept a graduate certificate when faced with another applicant with a master’s degree, so the graduate certificate is not as marketable or practical as a master’s degree.
Core Courses, Internship and Immersion Experience
Core coursework found in a typical master of science in science program includes:
- Experimental statistics I and II
- Introduction to data science
- File organization
- Database management
- Network and data security
- Data visualization
- Data mining
- Statistical sampling
A graduate internship may also be required. The student will be placed into a real-life data science work experience, and have the chance to interact and network with other workers and potential employers. Professors and employers grade the student’s performance during the graduate internship
Schools commonly require an immersion experience in a graduate data science program. This program consists of group case study work on a given topic. Students and faculty will meet in person and collaborate, providing more relationship-building and networking opportunities.
Key Competencies and Program Objectives
Competencies that employers expect graduates of master’s in data science programs to display are:
- Statistical analysis
- Data mining
- Machine learning
- Database management
- Network security
- Visualization of data
- Effective communication
