It was really insightful, coming from knowing almost nothing about statistics or experimental design, it was easy to understand while not feeling shallow. Just the right amount of information density.

Great Primer for what Data Science is about. It also provides the infrastructure of tools needed. This was what I was after, a way to provide other data scientist hardware and infrastructure support.

Worthless course. There should have been no need for this course and the fact that they charge money for this is disappointing. This module could have been easily merged with the next module (R- Programming). Just a few pages with instructions on how to install the required softwares and repositories would have sufficed.

This course could be summed up in one page or so. Very little content.
GitHub lessons good.

The course does not warrant the price, it has way too little information. Very dissatisfied.

Didn't learn anything in this one.

$38 is a lot to pay for tutorials about how to install software. This course takes only 20 minutes to complete. It is also obsessed with command line interfaces. There's a reason that they were left behind in the 80s. It does cover GUI software like Rstudio, which is ignored for the rest of the course. How about something on the desktop Github version? https://desktop.github.com/ So much easier to use.

I think there are only few contents.

Some interesting concepts, but way to simplistic in my opinion. Only reason I see to pay for it is the fact that it is a requirement in the Data Science Specialization

Completely useless. Just a number of boring videos of what you may possibly learn in Data Science Specialization.

Too basic content.
I have not learned anything with this course (installing R and RStudio should not be part of exercises or lectures).
I hope R programming course will be better

Way too basic for the price - almost no content - this is just setup - I resent paying for setup instructions.

Very short and just a basic overview on how to install a few tools that most of them I already had installed. All this course content could be packed into an introductory lesson instead of having to pay for it. I abandoned the specialisation because of this, I know it's a big business but at least you need to offer some value for the money

I don't have comment on the data scientist's toolbox. However, the payment mechanism of coursera is terribly designed.
I was continually paying the course without pre notice. The worse thing is, the coursera doesn't return the money after I cancel. At the same time, they don't allow me to enter the class. Really terrible.

Complete waste of time. This should be a course on its own, and much less be charged for. This should have been the 1st week of an actual class. This only dealt with installing a couple of software tools. Hopefully the following courses will teach something worthwhile.

This course was a loss of time and money. Except from week 3 material, the rest can be found on the internet and should be required by everyone who wants to take that specialization. This course doesn't worth it, it's just to take extra money from anyone who wants to learn about Data Science.

There is imply not much substance here. Everything here can honestly be integrated into other courses or offered as a free overview course of what data science is.

It has almost no content and isn't actually useful. I've heard later classes in the series are way tougher, so the ramp up isn't at all good.

Although the content is correct, quality models videos and materials is very low, wanted to make all the specialization, but I'm not satisfied with the quality of the course. It's a shame, because the JHU is an excellent University

Useless. The information content is close to zero. Just some blah-blah and a long tutorial to install software.

most part of this course is a duplicate of the "R programming" course.
microphone/sound of the teacher quality is very bad.
not original, boring, dividing this in "4 weeks" is too ridiculously long, this should be done in 1 week to enable users to take more time for the "R programming".
this course should be free. don't lose too much time on it, it's doable in a day or a weekend and move on to "R programming".
asking for so much money to see how to install R and github is a shame.
feels like this course has been added just to have a round number for the specialization.
even the survey in the end asking for feedback starts with a question not adapted to moment it's been asked "did you get a certificate?" of course i did not as i've just finish the course and now wait for my peers to review my final submission.

Certainly not worth paying for this course, only talks about how to install the tools.
Not able to take quizzes when you try to take the course for free.

Very bad course so far. Very little detail and Assignments are very hard to solve. Worst $500 dollars spent in my life, and the course isn't worth even $10!
I'm an online instructor myself and the quality of the course isn't worth its price!
