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.

This course is brilliant, but I expected more exercises to master more commands in R mentioned in the course.

This part of the specialization is very important since 70% of a data scientist work is get and clean data.

Allows you to deepen your knowledge in R how to get data. The final work was challenging, but possible :-)

Nice course. Far easier than R-Programming. Could be refreshed to match tidyverse workflow. Otherwise OK.

The assignments are sometimes poorly explained. Other than that this is a solid and very useful course.

This course is quite challenging but it provides me basic idea of tiny data which is very helpful.

Great course but would benefit of more hands on exercises done by the teacher during the lectures.

Overall very good but the class does not teach enough to make the course work easy to figure out.

I want to learn how to make an efficient codebook and README.
Using Github is a bit hard for me.

awesome course, will require a lot of reading and re-reading though - mainly for the R part.

First two weeks were not really valuable for me, sorry. But the las two actually were.
