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.

I really enjoyed and learned a lot in this course.
I feel a lot more comfortable with looking for and reading data. I learned how to clean data and getting it ready for further analysis. I think the course project was particularly good for completely understanding the process of tidying data and all the aspects it involves, such as writing a code book and a README file for accompanying it.
Furthermore, I believe I further developed my R programming skills, by learning how to code new things or things I already knew but in a more efficient way, by using new packages and techniques.
Moreover, I found Professor Jeffrey Leek quite engaging, very easy to understand and I had complete confidence in his knowledge on this subject.
However, I believe the course is slightly outdated. I was often disheartened and frustrated by not being able to replicate what was being done in the lecture videos. For example, there were many links that did not work anymore and sometimes information that simply wasn't correct anymore. I found the discussion forums and many mentors responses to be very helpful. I think this can easily be fixed by writing up an errata or updating the lecture videos.
