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.

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.

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.
