According to IBM, 90% of all the data in the world today was created in the last few years, and just about every last byte of it lands somewhere in the supply line that runs through Silicon Valley. The torrent of unstructured and uncategorized data that pours into the pipeline from billions of people doing billions of things every day creates a playground for the data scientists capable of transforming it into something companies can use to gain an edge in the marketplace.<!- mfunc feat_school ->
From e-commerce and healthcare informatics to retail analytics and finance, data scientists are a hot commodity in firms dealing with the problem of how to collate and derive meaning from the massive troves of data that come spiraling out of their business operations every hour of every day. Data scientists help realize the full potential of big data by bringing structure to it, finding compelling patterns, and advising executives on the possibilities and implications found within it.
According to the executive recruiting firm Burtch Works, data scientists on the West Coast earn the highest salaries at every level, handily beating out the closest competition, those in the Northeast, by at least $7,000 annually.
Data science, of course, has a permanent home in Silicon Valley where the biggest and most globally recognized tech enterprises on earth wrangled big data a decade before the term was coined, inventing an entirely new industry from the slag of their daily business functions. And when that by-product was discovered to be as valuable as the very products and services these companies offered, data science was born.
There is no longer a clean line between the software we interact with daily and the data these interactions generate. One informs the design of the other in ways that are hard to comprehend and impossible to separate.
Professional opportunities in big data are not emerging; they are here now, and California’s global tech companies are competing for top talent – scientists with the creative mindset and technical capability to take the company vision to the next level.
Preparing for a Master’s Degree in Data Science in California
Schools offering data science master’s degree programs expect candidates to have a strong background in the high tech arts, including an impressive showing in undergraduate studies. Data science is a demanding field, and with many applicants vying for limited positions, you’ll find that you need a lot more than just a bachelor’s degree under your belt to get your foot in the door.
Undergraduate Degree and Master’s Prerequisite Courses
It starts with your choice of major. Many schools that offer graduate programs in data science require candidates to hold an undergraduate degree in one of the following:
- Computer Science
- Applied Statistics
- Biological/natural sciences
Most schools require candidates to have a minimum 3.0 GPA in their undergraduate work, too, so this isn’t a field where anyone can just slide in without a lot of hard work and self-discipline.
Other requirements for admission into a master’s degree in data science often include:
- Minimum GRE scores
- Letters of recommendation
- Undergraduate coursework in:
- Computer programming
- Calculus I & II
- Linear algebra
It is common for data science programs to require candidates to sit for an admissions interview, during which time they assess their motivations and foundational knowledge.
Prepare for a Master’s Program or Skip it Completely by Attending a Data Science Bootcamp in Los Angeles, San Francisco, San Diego, Online, or in Many Other Cities Statewide
If all that sounds a little stuffy to you, there’s a high-octane alternative waiting in the wings that can get you prepped for your master’s application in record time… or maybe even bypass a degree entirely on your path to a high-paying data science job.
That alternative is attending a data science bootcamp. Entry-level bootcamps that accept candidates without a degree deliver fast-paced, intensive, practice-oriented training in data science that gives you the bare essentials with a focus on real-world projects that get you hands-on with the tools and techniques used in the trade.
Once rare, bootcamps are now becoming so common that even universities are running them. Although they do not result in any college credits, programs like the highly respected University of California Data Analytics Boot Camp do offer fast-paced training in subjects including:
- Python 3
- Statistical Modeling and Forecasting
- HTML and CSS
- Big Data Analytics with Hadoop
All of it happens under the close supervision of instructors with real-world experience, and typically using real-world datasets to solve realistic business problems with the same methods and tools you would use on the job. It all happens in just 24 weeks of night and evening classes.
In addition to being available online, that program is available on campus at these UC system schools:
- Berkeley Data Analytics Boot Camp
- The Data Analytics Boot Camp at UCI Continuing Education
- The Data Science and Visualization Boot Camp at UC San Diego Extension
- UC Davis Data Analytics Boot Camp
Privately-run University of Southern California also offers a bootcamp
USC is an IT powerhouse, and offers a comprehensive entry-level camp that covers the spectrum of analytics and visualization tasks and tools.You graduate from each of these programs with an extensive portfolio of projects that you have actually conceived and completed yourself. It’s all part of the bootcamp’s career-building approach that also includes mock interview preparation and resume reviews.
Bridge Programs and Massive Open Online Course (MOOC) Options to Bridge Gaps in Functional Knowledge
Many institutions allow students who lack functional knowledge in mathematics or programming to satisfy prerequisite coursework requirements and gain mastery of key concepts by completing bridge courses upon acceptance into the program. This option is reserved for those that have met and exceeded all other standard entry requirements
Typical bridge courses available as needed upon admission into a master’s degree in data science include:
- Fundamental bridge programs – courses in linear algebra, data structures, along with analysis of algorithms
- Programming bridge programs – training in such essential programming languages as C++, JAVA, and Python
Some students also choose to take a more proactive approach and complete massive open online courses (MOOC) to satisfy prerequisite requirements before applying to a master’s degree program in data science. MOOCs, offered entirely online, provide prospective students with a wide array of course options for supplementing their education. Online problem modules, lectures, and frequent interactions with professors are just a few of the hallmarks of MOOCs.
Relevant Personal and Work Experience
In addition to a strong undergraduate background in relevant areas of study, data science graduate programs also require candidates to have experience in data analysis, business analytics, business intelligence, programming, software engineering, etc. Many institutions also look for candidates with specific knowledge of:
- Machine learning
- Computational statistics
- Large-scale scientific computing
- Operations research
Experience—both personal and work-related—should reflect a candidate’s:
- Curiosity and creativity
- Ability to solve problems
- Ability to learn quickly
- Analytical mindset
As expected, California is home to a vast array of companies where you can gain the experience needed to enter a master’s degree in data science. The hunger for junior data analysts in Silicon Valley and elsewhere is ravenous, and staffing firms like Kforce, Volt, and Staffigo are constantly hiring for work at both the strategic level and the tactical level for undisclosed, but big-name, clients. LiveRamp Labs in Redwood City hires entry-level data scientists that help conceive and build prototypes of intelligent applications based on existing LiveRamp technologies, LiveRamp data, and other leading-edge technology from third-party partners and customers.
Preparing for Success on the GRE/GMAT
Entry into many data science master’s degree programs requires students to take either the GMAT or the GRE exam and score in the 85th percentile on the quantitative section. Preparation is key to success on these examinations:
The GRE Revised General Test consist of three question types, all of which reflect graduate-level thinking: verbal reasoning; quantitative reasoning, and analytical writing. The quantitative reasoning questions of the GRE measures a test taker’s problem-solving ability using the basic concepts of arithmetic, algebra, data analysis, and geometry.
The GRE website provides test takers preparing to take the quantitative portion of the exam with a guide found here. Anyone studying for the exam may also want to download the POWERPREP II software, which includes practice tests.
The GMAT exam consists of four sections: analytical writing assessment; integrated reasoning; quantitative; and verbal. The quantitative section of the GMAT consists of 37 questions involving data sufficiency and problem solving. The GMAT website prepares tests takers for the quantitative section of the exam by providing a number of study tools, including videos, sample questions, and guidebooks, found here.
