The key challenge to finding practical data analysis problems in the online domain is that the data provided in online practical sites such as Kaggle etc. are much cleaner and more manageable; whereas the data in real-world business scenario is much more complicated, unclean and unstructured. Therefore, there is no precise or absolute website or any other online source wherein students can get first-hand experience on solving practical data analysis problems.
Still, the best website to practice data analysis problem in Kaggle wherein students are recommended to formulate their own research questions; and then collect relevant data from scrapping different websites, portals, and government stats site. This would help them gain real-time experience in solving practical data problems.

Forget practice, go straight to real work

You will be much more incentivized to learn if you do things that you’re interested in. So forget practicing things out of a test or a curriculum. Instead, ask yourself what you want to build.

Some great resources:

  • Kaggle | You can look at other cool projects others have done. Find the one you like and replicate it. You can even use a similar type of analysis on other data.
  • Github | Google a specific type of analysis that you want to do and chances are that someone has done a version of it on github.
