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.

I thought it was good until Week three. I found some of the directions on how to download/set up programs very confusing.

Really gets me, so I renew my interest in learning new things, It´s a well implemented course to introduce you to RStudio

It forms the base. The examples should be recent and since its more from Bio stats etc, sometimes gets a bit confusing. .

Es un curso muy básico, introductorio de conceptos, herramitas como git y github, las consolas... Sólo para principiantes

The course was nice but seemed too trivial at times of discussion about basic tools like git and command line interfaces.

Some of the exercises were challenging to follow; however, I was able to complete after troubleshooting and researching.

It was really, a helpful intro to the concepts and tools to get someone - especially if new to the field - on the track!

it could be better if there is a true human being teaching instead of a female ai. it seems a little bit indifferent lol

Very good place to start. Tells you just enough to get started and also just enough to get hands dirty to keep learning.

Should be able to optionally select viewing the Mac or Windows installation videos.

There are no videos for linux users.

Good overview of the specialization. Probably very good for someone new to R and software development tools in general.

Assignments are useful, background is interesting, but meat of it is nothing you can't get from googling "Data Science"

Excelente curso. Yo ya soy usuario de RStudio y he aprendido bastante, especialmente del versionamiento de mi código.

The really great material were in Week 3. The first 2 weeks are too basic for anyone with at least some IT background.

El curso me parece excelente, pero tuve problemas con la plataforma, me borró todo lo que hice e incluso había pagado.

The content of the course is quite enriching. Besides the robotic voice, I enjoy every bit of the course interaction.

A decent survey of the material, which hopefully follows. A good but almost too easy class for such a deep subject.

Course content is good. I was able to get the basic understanding of git and github and also understood how it works.

It helps you to start, so installing software and so on. I recommend you to try applying for financial aid for this.

Slides and videos are a bit insufficient in order to finish course projects.

Apart from that, this course is awesome!

Although it does not affect the learning experience, the robot voice in the videos is a bit annoying, to be honest.

While the material is fairly basic, it is still very useful to future courses in the series. A good place to start.
