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.

•I felt I had to teach myself in this course. I feel I would have had the same learning experience if I had purchased a good R book.

•A lot of things covered in this course in a short time. Probably should have been 8 weeks with more homework done step by step.
