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.

Great course, you learn a lot of ways to find data and improve other skills as regex and the use of "dplyr".
Take it twice if needed, do not go pass this point until the science behind this course is well understood.
