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.

A high level view but very helpful for someone starting their Data Science journey. Good overall coverage of basics that helps in building a gradual understanding of the subject.
The only reason i haven't rated 5 stars is because there were lot of errors that i came across in the automated diction that need correction.

Organization of course was good. Sometimes, I felt that speed of the lecture is fast and I had to reduce the speed to 0.75% to understand important concepts. Improvements can be made in the transalation of text by robot, 'e-g' was being translated to EG instead of for example. Overall the content of the course was good

Good foundations course on the elements of R programming. It seems that there is very little engagement from instructors and the AI voice, while entertaining at times, is dated and there are much smoother AI voices that could be implemented. All in all, a good course and essential for the Data Science Specialization

A brief introduction and overview of data science and the specialization from JHU. It provides necessary information and materials for the following courses, but itself does not cover much technique details. Won't take long to accomplish but still necessary if you don't know Git, Github or background of data science.

very basic when you have at least some science background in terms of a Bachelor + almost Master Sc. degree, but good for repetition, Git Bash and Github was completely new to me, at the moment I am not 100% sure for what Github and Git Bash are useful, but I am sure I will figure it out in the upcoming courses :)

It was good and it helped me to explore github,git,R and Rstudio. The peer assignment was quite good as it was my first peer assignment..But,only thing is that instead of this format(using AI),U can use on-person teaching which will be good and interactive..
I felt sleepy with the crampy female robotic voice

The peer review is very subjective. The last question on the grading rubric is about whether or not the work was done by the student who submitted the assignment. One person said yes and another said no, so I only got half a point. I would have had 100% if not for this. I can prove that the work is my own.

Found that the automated lecture didn’t deliver the message as well as a traditional lecture. There was awkward delivery in terms of speech and phrasing from the automated lecture and I found it distracting. But the material was great and I feel prepared to start the rest of the data science specialization

The course overall has been helpful in getting started with R and data science as a method of analysis. But the robot voice is extremely difficult to listen to. To the point where I am drifting off because it is so monotone, and sometimes not interpreting the content correctly due to a weird pronunciation.

The course is pretty interesting, but there is not much substantive knowledge here. For that you must keep going to the other courses of the Specialization such as R Programming and the others. There you are going to learn data science in practice. Nevertheless, this is a good introduction to the topic.

The course helps me understand more about data science. However, I see that when instructing using an automated voice, the way the course was taught was kind of boring. I took longer time to digest and complete this course. Hope that in future to variate the voice, not just specific to one voice tone.

Good course, that brings goos insights on the basics about data science.
The lectures about Git and GitHub are not so clear - maybe this classes would better fit when the class already have a more advanced knowldge on the course's theme.
Thank you for the quality of the lessons and to make it available.

A good place to start of your entry to Data Science. You get to know what data science is, what are the tools used and get an idea of what can be done and cannot be done. The course even walks you through installation of r, rstudio, and git. It introduces version control system using Github too.

I really wish there were a few videos with real people in them. That computer voice is annoying, but the material was covered thoroughly, and I used the text option which actually was great. I also think it would benefit students if there was a book or some form of notes they could download.

A Good introduction to data analysis theory and tutorials on getting started with Rstudio and git installation and initial usage techniques. Consecutive course to compliment this would be R programming and Data cleansing and exploratory analysis as in John Hopkins Data Science Specialization

Very good stuff relating to Data scientist's entrance in the Data Science field but it should be more descriptive in terms of basic tools and softwares like git and github. Although the stuff is available over the internet but when you listen & see, you get more and more efficiently. Thanks,

It was a little to easy and the quizzes were not really necessary. Questions like "What courses are in the Data-Science Specialization?" don't help to controll my learning progress. However for a first, introducing course it was okay. R Programming is way more interesting and challenging <3

Didnt enjoy the voice on the automated videos, but was faster at reading than watching videos. The document didnt work for the Big data Section and had to watch the video for this. Good introduction and wished I had more questions to practice! Looking forward to R Programming section next"

It's a good start point for people who wants to start pursuing a data science career and haven't a statistical background. Explain the basic definitions of research analysis types and shows the very beginning of handful tools like how a git repository works and good editors for R scripts.

The course was good except for the updates that it needs. To link Github and RStudio, you need to create a personal access token on Github and use that as the password when it is prompted on RStudio. There is no mention of personal access tokens in the course so that needs to be updated.

The course is very basic but still contains useful information both on data science and some of the tools.
Unfortunately, because of how basic it is, I found the quizes focusing on trivial and subjective questions that are both hard to answer and not really testing any interesting skills.

i think is good course they explain to you Data science and all things about it and how to install and use the tools of data i think the problem is the robot that they used as speaker i think the voice of human better than robot for me and the translation for Arabic isnt really good .

One would need to do some additional hard research in between though to complete the course due to the automated video which skips a couple of steps including the discussion on the Git! Hope this will not be the case on the rest of the courses. overall Good course but 5 stars for me.

The tools needed are all explained well, including installation. Still getting used to the new Amazon Polly format. A few questions in quizzes seem to not align with updated material, but that could just be an intentional push to be resourceful. Looking forward to the next course.
