A project is more than just a Kaggle dataset

a few criteria that define a good data science project

Learnability- What did you learn in the Project
Capability – What capabilities were showcased in the project
Difficulty- How difficult or easy was the project
Potential Hireability- How likely are you going to be hired based on that project
Ability- What creative approaches did you bring to the solution

A few datasets I liked only from a teaching purpose- iris, Boston, mtcars, Titanic, German Credit and mnist handwriting
