This course provides an introduction of some important concepts and tools on a very important aspect of data science: cleaning and organizing data before any analysis. A must for any data scientist.

Easy, mostly instructive Course. The Assignments and quizzes are quite good, and illustrates the lessons very well.\n\nSee the videos for general presentation, but use the energy on the excersizes.

Course touches points very superficially. Need to have better reference material.

More examples of code running in parallel with the course work will be helpful.

Topics were OK but the focus on R and no other tools is frustrating

The course was good but a bit too versatile for such hard quizzes.
