Hailing from backgrounds that include math, statistics, programming, and even physics, data scientists are a diverse group. Still, there are a number of traits that seem to be universal among all of them: they are curious, innovative, analytical, creative—and highly educated. In fact, according to a 2015 study conducted by executive recruiting firm Burtch Works, 88 percent of data scientists hold graduate degrees.
Graduate-level study in a quantitative field like computer science, applied mathematics and statistics has historically served as the foundation for the profession.
More recently, field-specific graduate programs in data science have been developed, offering a more targeted approach to developing the multidisciplinary skillset necessary to isolate, organize, visualize and find purpose in large amounts of scattered and unorganized data.

Expected Outcomes of Data Science Graduate Programs
Data scientists are among a number of big data professionals who apply their sophisticated quantitative skills to derive useful information from massive datasets. However, unlike other big data professionals, data scientists possess the unique ability to store, retrieve, and exploit big data. In other words, their expertise lies with their ability to make sense of and derive insights from data before it has been organized, structured and given purpose.
Master’s programs in data science prepare students to:
- Work with enormous, unstructured datasets
- Extract data from multiple, disparate sources
- Transform data to meet operational requirements
- Load data for analysis retrieval
- Derive useful information using sophisticated analytical methods
Master’s degree programs in data science also arm students with the skills required to:
- Retrieve and summarize data using tools like Hadoop and MapReduce
- Write programs using languages such as Python and Java to retrieve and summarize data from Hadoop clusters
- Use statistical methods and tools like R and SAS to derive insight from data
- Use methods pattern recognition, signal processing, and visualization to derive useful information from data
Graduates of data science master’s programs often go on to work for:

- Marketing services
- Technology companies
The Master of Science in Data Science
The Master of Science (MS) in Data Science prepares tomorrow’s data science leaders to be capable of transforming big data into actionable information that can then be used in strategic decision making.
Master’s degrees in data science may also be designed as:
- Master of Science in Statistics: Data Science
- Master of Computational Data Science
- Master of Information and Data Science (MIDS)
Data science master’s degree programs provide students with a framework in computation, programming languages, and linear modeling and then build upon skills related to high-level mathematics, statistics, and computer science. Students learn how to analyze data, make visual representations of their results, and articulate their discoveries.
Data science master’s degree programs prepare graduates to become competent and versatile data scientists capable of skillfully and confidently:
- Constructing and testing hypotheses
- Creating and evaluating models
- Drawing conclusions and determining if the results make sense in the real world
- Exploring and improving the structure of available data
- Questioning underlying premises and reformulating issues
Data science master’s degree programs provide students with a project-based, interdisciplinary curriculum designed to prepare graduates to solve real-world problems by gaining insights from complex and unstructured data.
The curriculum consists of about 30-35 credits of core coursework in areas such as:
- Storing and retrieving data
- Exploring and analyzing data
- Applied machine learning
- Data visualization and communication
- Experimental statistics
- File organization and database management
- Data and network security
- Statistical sampling
Most data science master’s degree programs include the study of data science ethics, which allows students to develop the ethical and critical thinking skills needed to work with large data assets while ensuring the privacy and property rights of individuals and organizations. Some of the issues covered through a data science ethics course include integrity in the data science practice, honoring intellectual property rights, and respecting data privacy.
While many colleges and universities offer their data science programs as on-campus, full-time programs, which take between 18 and 24 months to complete, perhaps just as many have begun offering their programs in alternate formats that include:
- Part-time programs: Part-time data science programs feature a more relaxed curriculum load for busy working professionals. This type of format takes about 32 months to complete.
- Accelerated programs: Accelerated data science programs (often referred to as professional master’s degree programs) consist of a more demanding, compressed curriculum completed in about 11-12 months.
- Online programs: Online data science master’s degrees allow students to complete the majority of their curriculum requirements through online study. Institutions offering these programs may require students to visit the campus to complete an immersion experience.
Well-rounded data science master’s degree programs include capstone or immersion experiences.
Capstone experiences provide students with the opportunity to address an important data science challenge. These final projects allow students to demonstrate their ability to use the fundamental concepts learned throughout their program all while being mentored, guided, and eventually evaluated by faculty members.
While capstone experiences are indicative of campus-based programs, immersion experiences are often part of online master degree programs in data science. Immersion experiences are campus-based experiences that provide students with the opportunity to network with faculty and peers, meet data science professionals, and engage in hands-on workshops and community-building opportunities.
Admission into a data science master’s degree program requires an undergraduate degree from an accredited college or university. Some institutions require candidates to possess an undergraduate degree in a quantitative field, such as computer science, statistics, or physics. Other institutions don’t require the completion of a specific undergraduate degree but instead the completion of specific undergraduate courses, which would typically include:
- Linear algebra
- Discrete mathematics
- Data mining/database development
- Computer programming (e.g., Matlab, C++, Java, Python, Ruby, etc.)
Data science master’s degree programs require competitive undergraduate GPAs (3.0 or above, in most cases), as well as:
- Strong scores (85th percentile) in the quantitative section of the GRE or GMAT
- A resume showing professional experience in data management, data mining, data science, or a similar field
- Letters of recommendation
Data science master’s degree programs often accept applicants lacking all prerequisite coursework but who are otherwise strong candidates, provided they complete the required undergraduate coursework through a bridge program upon admission. Some candidates for these programs choose to complete the required coursework through massive open online courses (MOOCs) prior to admission into the program.
Graduate Certificates in Data Science
Data science graduate certificates are designed for individuals who have already completed graduate study in a quantitative discipline yet want to make the move to a data science specialization. Grad certificate programs allow students to explore data science in-depth and learn more about the numerous industry-based applications for this discipline.
Just a few of the titles of these programs include:
- Big Data Science and Business Intelligence Certificate
- Certificate in Data Science
- Certificate of Advanced Study in Data Science
