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.
As a business student from Bangladesh who is aspiring to be a data analyst in near future, I love this course very much. The quizzes and assessments were the places to check how much I exactly learnt.

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 have absolutely no idea how could this become a separate course - and one spread over 4 weeks. It is extremely basic, extremely general and extremely high level. It should be compressed to 1-2 hours and added as an _optional prerequisite_ to other courses in this specialization. I personally feel cheated out of my 29 USD.

They charge you to take a class that explains how to install a few programs. If you go to the program's websites, there is directions to install it anyway, so this was completely unnecessary. Waste of money. This class should give you some early training on R before throwing it at you in the next course without enough training.

The videos aren't videos, they are really boring slide shows. On top of that, the computer voice is really monotonous. it just keeps going and going. This approach to teaching has been a large disappointment for me. So in short this class is dull, tedious, and repetitious, and all-around lacking in variety and interest.

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.

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.

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.

I had a very bad experience with this whole course set-up. Especially the peer-grading, you have no insight on why they assigned this score to you - nothing.. ..especially when you know you did your course work correctly.. i will never come back to coursera.. waste of money !!!
por Jorge G B T•
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.
por Abdelrahman A•
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!
por Louise S•
A simple list of programs that needed to be installed would cover 90% of the course content. Some of this content is also repeated in other courses in the sequence. If you have any technical skills this entire course is extremely tedious.
por joan B•
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
por Siddharth K•
If you are doing this for certification then go ahead, but if your intention is to learn then this is not a good course. Its absolutely basic and most stuff you can find online without spending any money. Wouldn't recommend.
por Corey H•
In my opinion, most of this information should be free and available as a pre-req. for other classes (installing R Studio).
It was cheap, but in general, I thought I was going to be more out of this course than I did.
por YOGESH R•
Students generally move towards online course to hear a human explaining them those concepts. This new technique may be time saving for you but it was really annoying and unexpected (almost everything )
por Ryan P T•
$40 is way too much to spend just to learn how to install a couple pieces of software and sign up for a GitHub account. The entire course should have been the first week of the following course.
por Aayush L•
Is this a real course for a data scientist just installing shit and a peer reviewing for that screenshot and forking all repos ...very bad not worth to be with rest course in specialization
por Diana K•
Good time of day! This course is great! But I can't finish it as I missed deadlines and can't switch session!!! I missed 1 month already because of this bug:(
It's so frustrating...
por Sebastian S C•
Me inscribí en el curso y solicité una ayuda económica porqué supuestamente se dictaba en castellano. Pero esto no es cierto y no puedo avanzar. Por eso mi calificación en baja.
por Pablo A•
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
por Mahesh K•
This is pure theoretical course,
It's look like a Power Point presentation. Students can not easily understand this.
I do not recommend this type of teaching on Coursera
por Joao P P•
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
por Charlie Z•
Do not take this course if you want to get a job in industry. Python now dominates industry and R is basically obsolete. I will be switching to a course in Python.
por Jonas L•
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.
por Rajat J•
Good introductory course. However, an overkill as a separate course (and hence charging $30 for it). Courses 1 and 2 could have been clubbed together.
