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.

It was a nice experience to learn the cleaning part with library dplyr and tidyr

Maybe some more notes about the quizzes and the course project would be helpful.

Excellent, though I found the wording for the final coursework quite confusing.
von Thành N•
This course is amazing. But I hope there is some exercises instead of quizzes.
von Fede N•
Course is great! Many examples are given on how to get data in various format.

Kind of slow in the beginning but picked up to the end to give me a challenge
von Markus K•
The course was quite good, but the last assignment was really much too vague.
von Praveen k•
good course to start with cleaning data and how to get data from resources.
von Mike W•
Good overview of using R (and dplyr) to clean data into "tidy" dataframes.
von Victor R•
Helpful, but more than half of the knowledge is in the swirl tutorial.
good course, if there are more text mining content, it will be better
von Charlie d T•
some shortcuts on the viodes makes the replication of work difficult
von Hiva P•
for me the instruction for peer review exercises was not very clear
von Joshua K•
The course project is too vague. Perhaps this is done on purpose.
von JUYU K•
The project/assignment sometimes is not too clear on what to do.
von naveen k•
The course content must be more in-depth for auditing the course.
von Hoang H N•
Provide a good introduction to getting data and processing them.
von Andrew W•

von Yue Z•
Great course but do not offer sufficient practical exercises.
von Ankush K•
Not the most exciting course, but definitely worth it/needed.

in my opinion, with more details, we could learn more about R
