Top 7 Free Data Science Online Courses [For Freshers & Experienced]

Demand for data science experts has been on the rise. IBM recently predicted a 28% increase in the number of employed data scientists in the upcoming years. In today’s data-driven world, every organisation has joined the data collection race to extract valuable insights.

These insights are fundamental for companies since it helps them to build relevant solutions, design targeted marketing strategies, and make data-oriented business decisions – no wonder why organisations across all industries are increasingly investing in data science technologies. 

Apart from being a flourishing field, data science also welcomes students from different backgrounds – from computer science to economics and statistics to cognitive science. So, even if you’re not from a data science background, you don’t need to feel left out. With a few courses, certifications, and data science projects, you’ll be up to speed with all that’s needed for building a successful career in data science

Lucky for you, there are various free online data science courses and tutorial that can help you not only set your foundations right but also get hands-on experience of working with new technologies. 

Why Pursue a Free Data Science Course?

As we mentioned earlier, employers worldwide now recognise the importance of hiring candidates skilled in dealing with large chunks of data for information extraction. Modern challenges require innovative solutions, and hence, it is crucial for professionals to acquire trending industry skills like data science and data analytics

Today, with various automated tools and technologies to handle mundane and repetitive tasks like data cleaning, preparing, analysing, many elements of data science have become much more accessible. So, people can carry out data-driven operations (like predictive modelling) without needing to get their hands dirty with any coding or algorithms. However, this is a very mechanical approach to things. 

If you have a clear understanding of the fundamentals behind these automated tools, you’ll be in a much better position to use these tools more productively. You’ll develop a different perspective towards these tools once you get a grasp of their inner workings. Also, you might be able to create more optimised techniques to solve complex business problems.

Because of this reason, we recommend you enrol in a data science free online course. By taking up an online course, you can learn from the safety and comfort of your home. While some online data science courses offer certificates of completion, some don’t. So, make sure to check the course webpage for the course details.
