Great course content and very much informative with the different options of learning either through text or video. A good introductory course to the Data Science: Foundations Using R Specialization.

Nice Course. Basics are very well taught in this course.Thank you JHU and Coursera for this course. I have decided to donate 10% of my first salary to coursera once I am complete this and get intern.

Very light & not really consistent with the heavy workload of subsequent courses. Felt it could have been much much stronger explaining GitHub- which shows up as a problem in latter courses strongly suggesting that toolbox does not effectively cover GitHub for newbies

One thing to note, I am using a work computer, so our IT support had to add the software required. This was inconvenient for them because I had to put in several support requests as I progressed through the course even though I installed as much as I was allowed to.

I think the course was too superficial and didn't cover enough topics to be a standalone course. It could be part of a greater course. My feeling is that this wasn't worth $30 dollars, and that such a small course was put together just to charge for one more module.

As an intro, this course is probably pretty good. I, however, already had experience with R (although the refresher was useful). However, if you've taking a data science or machine learning course recently, I'd give this one a pass and head on to the next course.

Thank you for the fantastic effort. Here's some constructive feedback on the course.
It's a very basic course, could have included more material. Also, the audio quality is not that great. To make it better, I'd Include more walkthroughs for Git and GitHub.

Too little substance, though I do expect the rest of the series to be good as I take this as a setup course and my expectations for those are high. Having said that, perhaps it would be wise to charge less for this initial course or even offer it for free.

Some parts are good, but the presentations are something very boring because the fact that are 'automated'. Is the first course and the concepts are very basic and sometimes well explained but i expected a more interactive course. 3.5 / 5, maybe 8 / 10.

Really tough to review this class outside of the context of the other elements of the data scientist specialization. What was presented was straight-forward and quite well done. After I know how well prepared we are for next classes, I will re-evaluate.

This is a course to get you set up with all of the tools that you will need to go forward. No hard homework, but you will be ready to work. The intros into various aspects of the curriculum also serve to prepare you mentally for the coming weeks.

Useful steps for starting the specialisation, but should this really be a course that people are paying for? Come on guys. By the way, some R programming concepts could be introduced here and de-clutter the congested/crammed R programming course.

This course is a good start to give an overview on the toolbox you should be aware of to specialize in Data science or analysis. You don't need 4 weeks to complete to complete it! At best you could complete within a week or 2 days. Best of luck!

Not sure if we will come back to Git, but i thought that in this section it was covered way too superficially. Maybe the idea was that we should get to it ourselves, but i guess my expectation was different. Other than that, the course was ok.

Some video explanations are not so clear, so will be great to highlight some concepts, theory and methods or technical (with some reading), also will be great exhibit the latest news about toolbox(that is the current topic) or data scientists

This course stays on the surface and doesn't delve too deep, probably in order to not scare off people who are new to the subject. From what I've seen in the second course, the material becomes a lot more difficult, which I was glad to see.

Would have like to jump straight to the material. Although I understand some may need it, the command line course was pretty basic. This course on it's own doesn't give much. One can get started with Programming with R w/o missing too much.

The course is great. The website is absolutely awful. I can either never get into the class I am working on or I am enrolled in classes I never signed up for and not enrolled in the class I want. If I found a good option I would switch.

Fairly basic course covering the fundamentals, I would suggest to most people to complete this course concurrently with the R programming course or to complete it all in one go, as I personally completed it within a couple of hours or so.

While this is a good introduction to Data Science and the tools available, it might feel a little too elementary if you have had prior exposure to the subject. The final peer review project could have been a little bit more challenging.

Seems like the version of Rstudio shown in the course is outdated. As a results there are several more steps to take by yourself before getting the latest version of Rstudio working.
Some questions in quizzes not dealt with in the video

It did not meet my expectations. It is more an informative course than a specialization course. They thought they were going to go deeper into the use of statistical programs, they only cover details that you can discover for yourself.

I have mixed feelings. It was WAY too easy for me, but my wife did it too and it was about right in difficulty for her. But either way, I felt like it just taught you to install stuff rather than actually teaching meaningful material.

A good course as an introductory course. My career aspirations are not to become a data scientist so I don't know how much I am going to use the Github. Time will tell. I really enjoyed the videos and how the course is given. Cheers

Too easy if you already know anything about github or Rstudio, although I do understand the need for an introductory course. The "Experimental Design" video was the only really useful part and contained quite entertaining examples.

This is a very basic course. If you are already a software engineer you could zoom through this entire course in an evening. If you are not a software engineer and don't know what things like github are, this class could be useful.

it is not the best way to start your data science career for me as a student because it has a lot of reading and theoretical ways I don't think its good for a beginning start and I was hopeful for more practice I would love to do
