Highly recommended course for budding data scientist. I loved the John Hopkins univ pedagogy and peer review system. The content is great.

Covers all the basics of visualization in R. Well structured and there is plenty of opportunity to practice your newly acquired skills.

Excellent course, it has allowed me to learn the bases to explore and analyze data.

Dear teachers thank you for sharing your knowledge

Great overview on explonatory data analysis and preparing graphs in R. I could apply the now knowledge directly to my current work.

The course is interesting and values practicality. The exercises and the projects really helped me a lot in grasping the knowledge!

This has been a great course. Accompanies by a book, it constitutes a great piece of material about exploring and visualizing data.

This course really helps you to learn the fundamental exploration techniques. The assignments and the examples are really helpful.

Very good introduction to Exploratory data analysis for beginners, the material is structural, lectures are interesting and useful

A Must have course for beginners in Data Exploration and Analysis. The best part is that exposure to these amazing concepts in R.

If you really want to learn, Coursera is the best option. There is a myriad of options and sources this specialization provide.

The lectures in this course included theory and examples on PCA and SVD - however this was missing from the practical materials

If you want to know how to use plotting systems like ggplot2 and how to explore your raw data, this course is really Useful!!

Really good course, with amazing videos and examples. I have learned a lot and I think the projects were really interesting.

This was an excellent course full of useful exercises, assignments and lectures. I took these classes for the data analysis

basic plotting and getting the feel of data, this course really helped tackling that and seeing perspective in data analysis

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

Loved it , the K means was pretty difficult for me but others was a breeze as i had experince in ggplots before the course

EDA is essential part of data analysis and in this course the concept is well covered especially through the assignements.

i very much like the course book. The course book helped me most in really learning the material and how to build plots.

Peer reviews of other people's work extremely helpful. Learned more from that than any other part of the course. Thanks.

Excelente curso, requer bastante empenho, mas para quem é entusiasta do assunto como eu é um excelente ponto de partida.

Very exciting, Did you Know that just by exploring your data can help you reduce the list of models you want to try out

There should be more content devoted to SVD . more theory and quiz questions and workouts to emphasize the methodology.

Great course to learn how to play with data - a good intro to things like Kmeans and hierarchical clustering, as well.

Nice content. Make sure to take the SWIRL course offered. That really helps to get a hold on the course. Recommended!
