Very useful course. I suggest taking this course straight after R programming and before taking any other courses in the specialization.

The course content as well as the assessments are very good. I would recommend this course for everyone who wants to learn Data science

Really fantastic even as an experienced R user. This is helping me remould my habits and break some of the bad ones. Thank you so much!

The most important information I learned was the tidy data standard. Very useful and clear. It will make the analysis process easier.

The most crucial part of statistical inference or machine learning is tidy data and this course provides the basic tidy data rules!

It's useful and practical! Especially, the swirl excerises offered not only the method, but also a clear example of data cleaning.

The class was very interesting and useful, although I would have liked more opportunities to do web scraping in the problem sets.

This course is really helpful and very practical. Provides industry standard information and adheres to the scientific principles.

This course is one another step forward towards my data science specialization. I'm really enjoying my study about data Science.

Challenging and very educational. Needs a better explanation on the final peer assignment. Otherwise a great overall experience!

It gave me an overview of how to getting and cleaning data.The course is best suited for anyone who is a novice in data science

Great course, everything is well explained ant the exercises are challenging enough to really understand what you are studying.

I am so glad this course was available. Otherwise, I would noy have had an opportunity to build a data set in my everyday work

Good course material. A very good project at the end of the course that gave an idea about cleaning a real life huge dataset

good course for learning about tidy data. But have to say that the instructions for the coursework is not exactly very clear.

Really great course which helps to understand basics of data tidying. I've also enjoyed regex explanation, it's really clear!

Great course, some background needed. If you are taking the Data Science specialization program, then this is a great catch.

Thank you for the case study, very valuable to me to see how you downloaded all the data and began your exploratory analysis

I greatly enjoyed this course and I really got a lot of hands-on practice that I can apply in a real-world work environment.

Great course teaches intermediate and andvanced skills to manipullate and clean data. Begginers should make an extra effort

The Value of the course is in the course projects. I found that working through them really accelerated the understanding.

Great course, providing very useful information. It might be better to provide few examples for codebook and readme files.

Amazing course! Even after a few years using R in a daily basis, I still learned quite a bit of new / useful information.

Great course covering a wide range of data types likely to be encountered in the field of data science. Well explained.

Really great class. I found the lectures easy to follow. The quizzes and homework helped me master the course material.
