Is data scientist the sexiest job of the 21st century? That’s what the Harvard Business Review said back in 2012, andnowthe rest of the world seems to be catching up. Forbes has recently ranked data science the No. 1 career for work-life balance, while Careercast has named it the sixth-best job for 2015.

That’s partly because of high salaries (with an annual average of $115,000, according to Glassdoor), but also because there’s a growing demand for the job. Companies want workers who can look at the facts, figures and information their products or services generate to glean all sorts of insights that could boost efficiency, safety, customer satisfaction or profits, among other things.

“The applications are really broad,” says Shanji Xiong, chief scientist for Experian’s Global DataLabs, which uses data innovation to solve strategic marketing and risk-management problems in financial services, telecommunications and healthcare. “Almost every aspect of our lives today has data and a data scientist behind it. Whether you're driving your car, you're cooking your meal, you use your cell phone — every step along the way there's a lot of data science behind the scenes making it possible.”


We asked Shanji why he loves his job.

You can literally study anything and be a data scientist

There’s no such thing as a data science degree — yet, anyway. And while most data scientists do come from fields like computer science, engineering or mathematics, Shanji says, they don’t need to. “I run into data scientists who come from more liberal arts backgrounds: economics, finance, other sciences,” he says. “To me, data science is a whole spectrum of capabilities and profiles, because it’s constantly developing, you’re constantly learning, and it can be applied to anything — likely something you have some familiarity with.” All you need, he adds, is a little coding experience and a desire to learn.

It’s creative

If you think data science means just staring at a computer all day crunching numbers, you’re wrong. A data scientist is like a designer, with an equal dose of mathematical application and intuition. “The thing about being a data scientist is that, you have the data, but that data doesn’t talk to you directly,” Shanji says. “It’s up to you, the data scientist, to try to understand what kind of information is in the data and then designing the tools to detect larger patterns” — or more nuanced, niche information. “There are lots of companies — Google, Facebook, Microsoft — that look for and encourage out-of-the-box thinking.”

It’s rewarding

Another thing you might not assume about data science: It’s really fun. Shanji describes a work environment that’s built on collaboration, bouncing ideas off one another and working with people of all different backgrounds and skills. Plus, it can be rewarding. “We’re not concentrating on immediate revenue, but on longer-term, high-impact projects,” he says. He cites work that his company does with health services, to determine things like how to reduce a hospital readmittance rate or how to get patients to take meds. “Data science can do so much, but at its best it can be an advantage to our society.”


Want to become a data scientist? Here’s how

1) Take a free online course — to see if it’s something that you actually want to do. Shanji recommends a course in statistics or motion learning, which you can find at sites like Coursera.

2)If you decide that data science is something you want to pursue, go ahead and learn one one programming language that’s widely used in the field. That will allow you to do the next step, which is

3) Get your hands dirty by trying out a data-mining project. (Kaggle has a ton of tests you can play with.)

4) Befriend some practicing data scientists so you can get their feedback and perspective, and to see the sorts of projects they’re working on. LinkedIn, or another social media group, devoted to the subject is a good place to start.
