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.

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.

A necessary prerequisite for the other Data Science classes, but not really a standalone course.

I liked it because it helped me to configured the software that I will use in the next courses.

Good overview of existing tools but more information will be useful to dig into the data world.

I think maybe because I have computer science background, so I think this course is too easy.

I don't really think that this amount of information should exist as a whole separate course.

Good overview. But it is confusing for the first class when you have no idea about the topic.

Need more practice in R programing, Github, commit, branching, adding text, making directory

some information was interesting but in general I don't think it was crucial for learning R.

If you don't know any thing about data science, good introduction, otherwise a wast of time.

A very simple course, focussed on installing the correct tools on your computer to learn R.

Too little material for 4 weeks. All this could've been written in a PDF instead of videos.

the computer voice is very hard to handle.

low production value of the course in that part.

Video lectures where TTS, not at all engaging. Thankfully, text material was well written.

Overall the course content is good, but the power points are not engaging and interactive.

Very Basic level. A little difficult to stay focused without having an instructor around.

Very basic, may be a bit more use cases on Git would have been useful. But that's just me

the computer voice is not that effective.

linking Github and R studio is a bit confusing

Few content for an entire course. I think this one could be together with R Programming.

Wasn't as good as I expected, but still I learnt from it, I can say it's above average.

I am aware that this is the introduction to this topic but it was a bit long-drawn-out.

By Juan J E

I was already familiar with some content. it was a good starting point for may training

A good intro to the tools, but for anyone with prior programming experience unnecessary

Okayish course. This course will give you an introduction in RStudio and Data Science.

Too few activities for the time allocated. I completed this course in 4 periods of 2h.
