They’re part computer scientist, part mathematician, part analyst, and part trend-spotter, apart from having some critical non-technical skills as well. We’ll delve deeper into this later, but first let’s have a look at the common industries that are being benefitted by data scientists.

2- Industries able to leverage the power of data science

Each industry comes with its own big data profile that can be analyzed by a data scientist. Here’re some of the common industries that can leverage big data.

  • Government: Here, security and compliance are two prime concerns for data scientist They help governments to monitor overall performance, support constituents, and develop decisions. Data science training is appropriate for these.
  • Business: In today’s competitive business landscape, it’s simply impossible for a business to thrive without leveraging the power of big data. From customer loyalty to production errors to inventory management to efficiency improvement — analysis of business data is needed to excel.
  • Healthcare: Today, healthcare facilities are heavily dependent on electronic medical records with assurance of adherence to security and compliance. Here, data scientists can aid in improving health services by analyzing big data.
  • Telecommunication: Every electronic device gathers data and it needs to be stored, managed, interpreted and analyzed to improve product and/or service quality, eliminate bugs, and enhance customer experience.
  • Science: Though data has always been a key area of interest to scientists, emergence of data science empowers these professionals to gather, maintain, and analyze data through experiments.
  • Finance: For a functioning business in the finance domain, it’s imperative to analyze massive amount of data on different kinds of transactions and accounts. Like the government sector, maintaining security and compliance of sensitive data is one of the key responsibilities of a data scientist working in finance and related companies.

Apart from these, other notable industries, which are on the constant look out for data scientists, include social networking, ecommerce, smart appliances, and utility providers, among others.

I wrote about that here.

3- Key responsibilities of a data scientist

Though the key responsibilities of a data scientist depend on the project he/she is working on, it can be said that all of them are based on big data or complicated inputs. And all these responsibilities need a deep curiosity in order to be performed accurately. Let’s have a look at the common responsibilities of a data scientist, regardless of the nature and volume of the business.

  • Analytics: Analytical roles are imperative to data scientists where he/she designs, implements, and assesses advanced statistical models as well as approaches that are related to the business’s most critical issues. Here, statistical and econometric models are developed encompassing different problems related to pattern analysis, clustering, simulations, projections, sampling etc.
  • Strategy: A data scientist helps in developing business strategies to form new approaches by analyzing customer trends and behaviors etc — which are essential for product performance optimization and increasing revenue. Here, advanced statistical techniques are implemented to gain actionable insights. Sometimes, unstructured datasets are also analyzed by the data science professional to create manageable analytical processes.

Apart from these two, a data scientist has to stay updated about relevant industry’s trends continually to provide useful recommendations to the business.

Value-based programs and strategic initiatives are two of the key areas that are such a professional focuses upon. It’s important to understand that a data scientist’s role has to be collaborative. It means in order to solve complex business issues, he/she has to closely work with other teams like the IT department, product managers, data engineers, data analytics team etc.

4- Future scope for data scientists

Now that you know why these professionals are in massive demand, it’s important to see whether there exist an adequate number of data scientists. The truth is, the number of these professionals is just a handful, while the demand for them seems to be increasing by the day.

As businesses lean more and more toward machine learning and artificial intelligence, there’ll be more jobs than available experts to fill them, and perhaps this is the reason why data science has become one of the fastest growing tech employment fields today.

5- How to become a data scientist?

To begin with, you need to have a robust acumen of sophisticated visualization and adequate knowledge of statistical techniques that are used to derive forward-looking insights. So, what are the critical skills and attributes of a data scientist? Let’s have a look.

  • Coding: You should know how to write codes and should be comfortable dealing with an array of programming tasks. These programming skills should encircle different aspects — from handling large volumes of data, dealing with real-time data to managing unstructured data, managing cloud computing and working with statistical models — everything should be taken care of. Python is the coding language typically used in data science roles, together with Perl, Java, C/C++ etc.
  • Critical thinking: It’s one of those skills that would set you apart from the pack. Critical thinking enables data scientists to implement objective analysis of facts on a given problem or fact before they can render judgments or formulate opinions. A business decision or problem has to be understood clearly before a model, which is critical to resolving the issue or supporting the decision, can be developed. It’s all about evaluating a situation or problem from multiple points of view, and not about looking at things with the eyes wide open.
  • Mathematics: If you don’t like or aren’t proficient in mathematics, probably becoming a data scientist shouldn’t be your career goal. You’ve already learned that massive amounts of data are what you will have to work with in this field. Thus, it’s imperative for you to leverage deep knowledge in mathematics to develop statistically relevant, complex operational or financial models that are capable of shifting or developing key business strategies.
  • AI and machine learning: Adequate knowledge of high-end techniques like reinforcement learning, neural networks, supervised machine learning, natural language processing, adversarial learning etc are a must for a data scientist. As huge volumes of data are being constantly collected, these cutting-edge technologies help a data science professional to make the data speak what’s needed by itself.
  • Communication: Regardless of how advanced a technology is, there’s always some integration between data, applications, systems and humans. A good data scientist should be able to communicate properly with different people using data as a major attribute. Type of communication can vary to a great extent — from the challenges with data quality, to technology and computational resources to distill complex technical information into accurate, easy-to-understand format — everything should be properly communicated to help business leaders direct business processes.
