About the Course

In this course you will get an introduction to the main tools and ideas in the data scientist's toolbox. The course gives an overview of the data, questions, and tools that data analysts and data scientists work with. There are two components to this course. The first is a conceptual introduction to the ideas behind turning data into actionable knowledge. The second is a practical introduction to the tools that will be used in the program like version control, markdown, git, GitHub, R, and RStudio....

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.

This course is more of an overview of what is to come. A lot of what is presented here could just be in the format of a word or PDF with a series of links.

It does nothing better than just a PDF file... I would appreciate if they actually provide a PDF file, so everything is integrated and no loading time.

Not really enough content to be a course in it's own right, should be additional material as is useful, but definitely not a requirement.

It is really basic course, I expected much more even if this is offered only for $29.. (the cheapest course in the specialisation)

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

I've taken a class in R. Half the quiz answers are wrong and is really overall pointless as a course.

The course contains almost no valuable information. It is not required to spend 4 weeks for it.

It's a course which is designed to preview the other courses. It could easily be eliminated

It's boring. The robot's voice is annoying that's why I can't focus on the lesson per se.

Too compact and short. Should be integrated to other courses.

Too basic

I would like to report some major issues with the new interface.

1) We don't have access to the slides anymore. This is a major issues since some of the slides content important links. These links are not shown in the transcript (I've double checked).

2) When we try to download the videos, subtitles or transcript, the resulting file name is the same for all content of the same type. More specifically, all videos are named "index.mp4", all subtitle files are named "subtitles.vtt" and all transcript files are named "subtitle.txt". This makes it more difficult for the student to save the files. In the previous version I would only right-click and saved in the right directory. Now, I have to right click, type the right name (which could be long sometimes) and then save the file.

3) In the previous interface, it was possible to see all the threads we were subscribed to. It is no more the case. It is not a problem right now, because there is not a lot of posts, but in cases where the number of post increase, it will be a pain to go through the list of threads and find the ones of interest.

Please ignore the review for now, I couldn't submit my comments without reviewing the course.
