where can beginners find example business reports in Excel, R, Python for learning?

#1
I'm having a difficult time grasping all the concepts. I am completing a MOOC project which is a business report of a car market or housing market and would like to find sample reports to see examples of visualisations, statistical analysis and how a report is worded for business managers/clients.

Where can beginner analysts find example reports for example markets?

Thanks
