As said by Clive Humby, UK Mathematician and architect of Tesco's Clubcard, Data is the new oil and is valuable only when refined. As the world around is getting ready to embrace data driven business models, it will definitely generate huge demand for data science professionals. While pursuing a data science course sounds like a good prospect, one may also think what is it that a human can contribute towards data analysis when machine learning models would be calling the shots with data processing in the future. Here is the fact: Many business people distrust processes they don't understand. They need humans to act as a bridge between the data and its users. Data Science as a profession is here to stay. So, be it a fresher or a professional; if one needs to learn data science for career improvement or to just test the waters, here are the top 10 free data science courses available in 2022.
