This course is really a challenging and compulsory for any one who wants to be a data scientist or working in any sort of data. It teaches you how to make very palatable data-set fro ma messy data.

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.
