Avis et commentaires pour l'étudiant pour Développement de produits de données par Université Johns-Hopkins

very helpful and teaching. learning practical tools for producting data products. examples in the course are not very complex, but give a very good intro for several tools.

Course content was helpful. Some confusion in assignment questions not aligning with what was covered in lectures where it would have helped to clarify that was intentional.

this curious course teaches about tools and techniques for communication with audiences on data science. some tools are very interesting and deserve a deep research from the learner, this course is mostly informative about the potential of such tools.

This course was amazing, it could definetly be more deep in each of the subjects, but gives you so much practice in tools that are very useful in the day by day of a data scientist

I learned very useful techniques

discovery of amazing tools and possible applications of rstudio and additional packages.

good pace of the course

Great course, practical and very informative

Really enjoyed this course. But you can only get as much as you put into it. A lot of students end up doing pretty mediocre apps that contain just enough to pass but never get creative. If you want to get as much as you can, then put some effort and create a nice app/presentations.

a very good beginner level course for those learning how to develop Data Products in R.

A lot of useful parts for visualization here! plotly and shiny are super useful in a business context. swirl and leaflet a bit niche perhaps.

Demanding if you are not used to do this kind of things, but, worth It if you give yourself a time to get into it.

Excellent course (like the previous 8 in the specialization) and very useful for anyone working with data and involved in data storytelling. Brian (the teacher) does an awesome job explaining the concepts and how the functions and scripts in R work and interact with each other to bring about shiny apps and other visualizations. A big "Thank you!" to everyone who created this course!

Awesome Lessons!

I learned how to build shiny application and today I'm very happy!

Great projects

Great course!!!

This course helped to get the knowledge how to create shiny apps and r packages. Very usefull, thank you every lecturer and masters how create this course.

Awesome course, maybe more complex examples, but is fine as an introductory program.

Good content, useful assignments, some of the tools talked about are out of date

nice aand easy. I do not know why you focus on creation of custom libraries withou any practical assignemens on it

Very useful, very well taught. I enjoyed the project as well.

Very useful stuff, and nicely presented too by Brian Caffo.

excellent course!

Very good course for creating your own data product

Great course with great materials. Easy to understand and to learn.

great course.
