What Are Data Scientists?

Jeff Hammerbacher and DJ Patil neologized this immensely trendy term. 

A data scientist collects, analyzes, and interprets massive chunks of data using machine learning and predictive modeling. Their foremost challenge is to recognize the most crucial business problems and their solutions.

For instance, data scientists at Tendril – an energy software company, implemented a hybrid approach by merging collaborative and content filtering to offer analytics, energy product recommendation, and consumer-based solutions. 

So, as you can see, these guys can decipher complicated data problems with their rich expertise in specific scientific disciplines related to statistics, mathematics, and computer science. 

Responsibilities & Job Titles of Data Scientists 

A data scientist’s principal responsibility starts with data collection and ends with business decisions, which is in short called data analysis. They collaborate with subject matter experts to create, maintain, and analyze data to deliver business insights. By recognizing data analytics problems, they can provide the most significant opportunities for the company.

Typical career opportunities available in the data science field are:

Data Scientists

They are usually expert-level, experienced professionals who can make data-driven business analytics and solutions by collaborating with other functional teams and using statistical modeling. A data scientist uses predictive modeling to improve customer experiences, marketing, sales, revenue generation, and much more. 

From Netflix recommendations and Facebook targeted ads to optimizing shipping routes – almost every industry involves data science experts.

Data Analysts

These professionals use statistical techniques to maintain databases, classify data, and analyze results. A data analyst helps management prioritize business needs by creating various reports and dashboards that provide hindsight into the business. So, sharp quantitative and technical skills with strong business aptitude are necessary to be a data analyst.

Data analysts add value to the company by making data easy to understand that supports companies in decision-making. For example, data analytics at Amazon Fresh and Whole Foods analyze buyers and suppliers for further improvement in the sale process.

Data Engineers 

They assemble complex and large data sets to solve problems and drive business value by creating robust infrastructure and applications. Data engineers make data pipelines and switch them from one system to another to ensure data is available for a data scientist for further assessment. Hence, they are in constant contact with data science professionals.

Developing end-to-end data engineering pipelines, data preparation, data integration, cataloging, streaming, and masking for faster insights are their core duties.

How to Become a Data Scientist?


Famous data scientist Drew Conway drew this diagram on data science known as the Conway Venn Diagram. Data science consolidates maths/statistics, technical skills (like hacking coding), and substantive expertise (i.e., business acumen).

Here are the data scientist qualification criteria to become a highly-skilled professional.

Education & Certification

Bachelor’s or advanced degree in mathematics, data science, statistics, or computer science would be good to have to begin your career as a data scientist. 

Several universities globally, such as the Institute for Advanced Analytics at North Carolina State University, recognized that employers today want data scientists who can serve as programmers and team players. Hence, data science got its origin in academics as universities revised some programs to bridge this industry’s skill-gap.

Nowadays, numerous certification opportunities are also available, such as: 

  • Microsoft MCSE Data Management and Analytics
  • Dell EMC DECA-DS
  • University of California, Berkeley: Machine Learning, Statistics for Data Science, Deep Learning in the Cloud and at the Edge
  • Coursera: Data Science: Foundations using R Specialization, Johns Hopkins University
  • Coursera: IBM Data Science Professional Certificate
  • Datacamp: Data Scientist with Python
  • Youtube: Sentdex by Harrison Kinsley
  • Youtube: Python Programmer by Giles McMullen-Klein

Technical Skills

  • Advanced programming: Covers demonstrated experience in languages like Python, Scala, and R to handle complex data analysis and ML algorithms.
  • Statistical analysis: Statistical analysis skills include in-depth knowledge of multivariable calculus, linear algebra, and statistical techniques to comprehend data and drive insights.
  • Big data tools: Learn big data visualization tools and frameworks to work on big data like Tableau, Plotly, QlikView, Hadoop, Hive, Pig, and others.
  • Cloud computing: Get hands-on experience on cloud platforms data tools and cloud computing knowledge, including Windows Azure, Amazon Web Services, Google Cloud, or IBM Cloud.

Business Acumen

Lastly, strong industry understanding is also essential for useful business insights. So, along with data analysis, a data science professional must also prioritize business to identify problems. This way, they can understand the core goals, needs, limitations, and datasets of an organization to simplify the decision-making process and suggest relevant solutions.

Scope of Data Scientist Jobs

Do you know that the data scientist profession topped the list of “50 Best Jobs in America” by Glassdoor continuously from 2016 to 2019? 

The tremendous growth of data has changed how data analytics is performed. Traditional BI tools are incompetent to analyze the massive and unstructured datasets. Smarter and more advanced analytical tools for collecting and processing data became the need of the hour as they took over outdated BI tools. 

This whole process is moreover possible only with the help of data science professionals. The dominant capability to collect data from the physical world is one of the driving elements of the ever-growing demand for data science professionals. Harvard Business Review even acclaimed a “Data Scientist’s job to be the Sexiest Job of the 21st century.” 

By employing data scientists, many long-standing companies can sustain and grow in the period of invariably emerging technologies. For instance, data science experts at Philips implemented an array of machine learning methods to enhance its performance and the healthcare industry. 

Philips uses data science and AI technologies in various segments, including marketing, sales, IT, supply chain, HR, finance, and others. One such use case is its ML-powered OncoSignal, which helps diagnose the type of cancer and its predicted therapy response by mapping signaling pathway movement in tumor samples.  

Even IBM proclaimed that the data science segment would grow exponentially by 364,000 vacancies in the U.S. As more and more companies keep adopting Big Data, ML, and AI, the scope for skilled data scientist jobs will undoubtedly amplify. 

Thus, the Data Scientist job title will evolve hugely to introduce a plethora of diverse roles. Since big data, ML, and AI keep developing, job prospects will also have to transform to cater to the progressive learning curve of Data Science.

Which Industries Need Data Scientists

Whether a financial institution aims to analyze its creditworthiness of its customers before granting loans, or an agricultural scientist aspires to gauge and compare the rate of increase in the current year’s wheat yield to last year, or an e-store decision to offer deals to its loyal shoppers – data scientists are the necessities in every field to process a significant amount of structured and unstructured data. 

Hence, the emergence of data science has generated job opportunities in diverse industries for aspiring professionals. Let’s have a look at the sectors that highly demand them.


The volume of customer data, website traffic, and accommodation information requires data science experts to process massive amounts of data. Using demographic analytics to examine bounce rates from travel websites, a data scientist can optimize search results for the visitors.

For example, Airbnb found out that its users from specific regions would click the neighborhood link, browse the page but leave without booking. So, the company replaced neighborhood links with the top travel destinations for those regions’ users as a test. It ultimately led to a 10% improvement in the lift rate. Besides, Airbnb offers better results to its customers by optimizing their search engine, enabling them to locate the right hosts.
