Maven Analytics now provides open access to their datasets through what they call their “DATA PLAYGROUND“!
They offer 21 datasets including a range of different data (time series, geospatial, user preferences) on a variety of topics like business, sports, wine, financial stocks, transportation and whatnot.
This is a great starting point if you want to practice your data science, machine learning and analysis skills on real life data!
Maven Analytics provides e-learnings in analysis and programming software. To provide a practical learning experience, their courses are often accompanied by real-life datasets for students to analyze.
