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.

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.

Fine for what it was but really did not need to be its own course. Could have just been tacked on to R Programming.

Me pareció un curso bastante completo. Tuve algunas dificultades con el uso de Github pero aún así pude progresar.

I expected more but this is really just basics and this is little bit bored because of the AI was the instructor..

Well structured and easy to follow. Most importantly, the onus is placed on the student to explore and self-learn.

A simple introduction. Easy to cover very quickly, however important to understand the basics before progressing.

it is a good overview but I found myself needing to go outside the source provided to learn about git for example

By Ming T

it introduces some very useful tools- such as version control with github, and the explanations are fairly clear.

You'll install 'R', 'R Studio'.

Will link R Studio with GitHUB

Will learn certain steps as introduction.

[That's it]

O curso é bom, mas achei a fala robotizada estranha e acho que a linguagem R está perdendo terreno para o Python.
