I'm doing Data Analyst nanodegree from udacity. I'm confused between the difference even after going through the lecture a few times.

  • $\begingroup$ Could you give us a sentence or paragraph from a lecture with each example? It's hard to say exactly what someone meant without more context. Tidy data typically means well organized and not needing lots of preprocessing to get it into a format you can use, whereas good quality data might mean not containing errors or containing strong predictive information. $\endgroup$ – Imran Aug 18 '18 at 3:09
