18 Resources to Learn Data Science Online

It’s been called the ‘sexiest job of the 21st century’, the ‘hottest job of the decade’, and is the fastest-growing field in tech at the moment – the impact of Data Science in today’s world cannot be overstated.

But what is Data Science?

As a discipline, data science involves the collection and study of data – both structured and unstructured – to gain insights and information that can be used by organizations to devise effective strategies. By collating data over a period of time, patterns can be identified that enable companies to find new market opportunities, enhance efficiency, reduce costs, and place themselves at a competitive advantage in their industry. 

Why Data Science?

Due to rapid technological advances, especially in areas like mobile advertising, social media, and website personalization, a massive amount of data is being generated on a daily basis. These data volumes have resulted in industries having to become data-savvy & adapt to the new landscape – or risk falling behind the competition. Institutions both public and private have realized the need for Data Science implementation within their organizations. Universities have responded to this need by introducing data science courses for learners of all backgrounds.  

Why Should I Become a Data Scientist?

A recent study by McKinsey indicates that the demand for Data Scientists is on the rise, with an estimated 50% demand-supply gap by 2018.

Skilled, certified data scientists are among the highest-paid professionals in the IT industry, with the median salary for entry-level data scientists at $91,000, and managers making as much as $250,000 a year.

How Do I Become a Data Scientist?

With this in mind, we have put together a comprehensive list of Data Science courses, online tutorials, and resources to help you become a certified data scientist and build a career in the field. Whether you’re looking for full-fledged university courses or just to stay abreast of the latest developments in the industry, we’ve got something for everyone. Read on to find out more!
