What Does a Data Scientist Really Do?

GettyImages-1449172934 (1)Data Science as we know it today knows no boundaries. Though its origin is rooted deeply in tech, it’s rapidly becoming a must-have function across industries, including Life Sciences, Healthcare, Retail, and Telecommunications.

Despite this prevalence, the terms “data science” and “data scientist” are often misunderstood and sometimes even used to describe a wide range of data-related work. When really, most Data Scientist roles require a fine-tuned skillset that incorporates a healthy mix of technical and business functions.

The following insights outline the key attributes that define a Data Scientist.


There’s an unprecedented amount of data floating around today - which means companies need Data Scientists now more than ever. They’re bringing Data Scientists into the picture to transform a sea of data into actionable insights. With combined skillsets in computer science, statistics, and mathematics, they serve as big data wranglers, analyzing large sets of (sometimes messy) data. Most importantly, a Data Scientist’s goal is to tell a story with the data and provide actionable plans for companies.

But what’s so important about all of this data? Insights provided by Data Scientists can have a profound impact — both on a small and large scale! On a small scale, companies are better equipped to strategically and objectively solve their biggest problems, which can really impact their ROI and bottom line. On a large scale, Data Scientists can change the world for the better. Now, key industries can extrapolate and utilize massive data sets to develop life-saving drugs, solve population health needs, and even combat global warming and similar issues. If you’re a job-seeker exploring Data Science, you get to choose your focus.

Really, there’s never been a better time to work in such a critical field. When you’re applying for Data Science roles, you need to come prepared with a solid understanding of the core competencies recruiters seek in a candidate.



When it comes to education, you’ll find that most employers look for Data Science professionals with advanced degrees, such as a Ph.D. or a Masters of Science in Data Science. They’ll also consider Bachelor’s level degrees in Engineering, Computer Science, and Mathematics.



Having the right mix of technical and business-level expertise will also serve you well. Data Scientists must have a foundation in computer science, math, and data science and analytics. Some other must-have skills include predictive analytics, statistical modeling, big data, data mining applications, data visualization and storytelling, and data-driven decision making.



Finally, the importance of knowing your audience cannot be understated! Most candidates that land a job in Data Science have top-notch presenting skills. That’s because this type of role is typically required to talk to mid-to-senior-level individuals about the data and, more importantly, at their level. More often than not, Data Scientists are tasked with presenting the same data, just to different audiences - i.e., to the CTO, CEO, Senior Scientists, internal teams and internal stakeholders. Sometimes, candidates are also required to give a short presentation (30-60 minutes) to different stakeholders as part of the interview process. Don’t be surprised if this happens to you!
