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.
See the videos for general presentation, but use the energy on the excersizes.

A reasonable course. Could use a little more focus on dynamically creating a codebook.

Very useful course. It's worth to add slides and to make sound of lectures bit louder.
