Avis et commentaires pour l'étudiant pour Exploration analytique de données par Université Johns-Hopkins

Loved it! It took me longer than expected due to work and family issues, but I went so many times to the materials and even use some ggplot2 for work that ended being quite fulfilling.

Work thru the Swirl exercises definitely helped. Great course.

I loved it, it improved my R skills in plotting and also gave me nice insights!!!

Da best

Short course for understanding the subject.

All of the quizes and assignments we're able to be completed with the material provided in the course videos.

An extremely interesting course, with many practical applications many of which I've applied in my day to day work already.

awesome course to learn exploratory data analysis using R programming language.

Some real stuff

Great knowledge and instructor, as usual.

Useful. very clear and easy to review and learn ggplot and other useful things

The right amount of theory and practical. This course will take you through the process on how do you ascertain what's important? and how to find that needle in the haystack? . Absolutely recommend to take this up.

Excelente curso e instructores!

Very useful experience

good course with example and assignment, we get the real feel of doing things.

Nice course! Workload was just about right. clear lectures and well-designed projects.

This was an important class because in future classes in the certification peer reviewed projects require some sort of exploratory data analysis.

I was able to learn the material presented over the time of the course. It's a lot of material to cover in the time I could commit to it but I feel confident using the tools and methods presented. The projects were very valuable both from getting to practice the methods and tooling and also from seeing how other students approached the solutions. I really helped put all the options into context and highlighted the value of using the different tools and where to use them. Only knock would be sometimes the background noises in the videos were distracting.

Very fruitful course on how to approach issues and use plots to deal with it

Amazing course content and assignment :)

Excellent course!

Great course. This course required us to create multiple plots using different R libraries created for the purpose. Although ggplot2 seems to be very popular, the base plot system and the lattice plot system provide compelling alternatives.

very handy and saves a lot of time for making plot with R

Prof. Peng teaches you not only how to use the r base plotting system but also how to make wonderful graphs using the lattice and ggplot2 packages. Awesome course!

Loved the course! Super useful tutorial of the different plotting systems, and basic exploratory data analysis. Very practical and hands-on, which is what is needed for this kind of work. Assignments were relatively simple, but I think they got the key points across.
