Companies and organizations in all industries are collecting more information than ever before. However, interpreting, organizing, and applying all that data can prove challenging for even the most sophisticated organizations. Data scientists extrapolate meaning from raw data using algorithms and data analytics programs. As naturally inquisitive and critical thinkers, data scientists ask questions, challenge assumptions, and identify trends difficult for most people to see.
The field's growth in recent years and salary of $110,000 a year explain why Glassdoor named data scientist the best job in America in 2018. Generally, data scientists also report extremely high levels of job satisfaction.
Should I Get a Master's in Data Science?
If you want to enter the field of data science, earning a data science master's degree can open many opportunities. Although some entry-level positions accept candidates with only a bachelor's, many employers prefer to hire prospective employees with at least a master's degree. Completing an internship while still in school can give you a competitive advantage over your peers.
Professionals already working in data science and individuals looking to change careers might prefer the convenience and flexibility of an online program. On the other hand, students coming straight from an undergraduate education may like the idea of a traditional on-campus program. On-campus programs usually offer more networking opportunities for new professionals.
Data science master's programs teach students hard skills in mathematics; diffusion geometry, matrix computation, and statistics; programming and scripting languages; distributed computing systems; relational databases; data modeling and mining; visualization; and machine learning. The best best data science master's programs also teach students the importance of so-called “soft” skills, which includes curiosity, creativity, storytelling, project management, communication, and ethics.
In addition to education, students attending a data science master's program receive several career benefits. While in the program, students can network with their classmates and instructors. These informal connections can often lead to job interviews and other opportunities. Most colleges and universities also host career centers that provide assistance with internships and job placement, advice for fine-tuning resumes and cover letters, workshops, and mock job interviews.

How to Choose a Master's Program in Data Science
Choosing the right master's in data science can seem overwhelming. Students need to consider many different factors, including school location, program length, cost, and accreditation status. If you attend an on-campus program, the location of the school can affect your employment opportunities, cost of living, and overall quality of life. Location can prove important even if you choose an online program. Some online master's in data science degrees require students to complete in-person residencies. Location also affects cost; most schools charge out-of-state students higher tuition rates.
Many factors can affect program length, including if you attend school on a part-time or full-time basis. Part-time students usually take longer to finish programs. However, these students have an easier time maintaining a full-time job or other obligations. Certain programs allow students to graduate sooner by doubling up on credits, taking classes year-round, or earning credit for previous training or work experience.
Students should also look at each school's curriculum. Each program offers different classes, concentrations, and thesis or project requirements. Look for programs that offer classes and specializations that deal with the specific topics you wish to study more closely.
Before you begin applying to programs, you should figure out how much you can afford to spend on your master's. All programs list tuition rates on their websites, as well as information about financial aid.
Programmatic Accreditation for Master's Programs in Data Science
Before you decide where to complete your master's in data science, make sure any schools you consider hold regional accreditation. Accreditation demonstrates that a college or university meets minimum quality standards agreed upon by the larger educational community. If you do not attend an accredited school, you may not receive financial aid or transfer credit.
Programmatic accreditation indicates that an academic program or department meets standards set by a particular field or industry. These programs have been proven to give students the skills they need to succeed. For the field of data science, programs at the undergraduate level usually receive accreditation from the Computing Accreditation Commission of the Accreditation Board for Engineering and Technology. Data science programs at the master's level do not currently receive programmatic accreditation.
Master's in Data Science Program Admissions
The admissions process for data science master's programs varies from school to school. Traditional on-campus programs tend to require more application materials. Online programs usually take less time to apply to; however, certain schools require students to demonstrate that they can succeed in an online program. All master's in data science programs require a bachelor's, usually in a related field. Most of the time, candidates also need to meet a minimum GPA requirement.
Schools tend to request official transcripts from all previously attended colleges and universities, letters of recommendation, and GRE scores. Most schools also require an application fee, ranging from $40-$100. Some programs ask prospective students to submit answers to essay questions or personal statements describing their interest in the program.
It often makes sense to apply to multiple schools in order to increase your chances of acceptance. Apply to a combination of programs, including some you feel confident you will get into and others that might seem like a stretch. To avoid wasting time and money, only apply to schools that you would seriously consider attending.
