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.

This could be wrapped into one of the other courses since its just environment setup.

Pretty simple, the Univ of Michigan Data Science with Python set the bar pretty high.

A little boring. Necessary if you have ABSOLUTELY no experience with data analysis.

Good starter setup. Looking forward to the technical portion of the Specialization.

the course is good but the language is little bit hard because it is auto generated

This was a good intro for novices, except the automated robot voice was annoying.

It`s too introductory. The methodology with an IA voice it`s not comfortable yet.

The course was very limited, it should have been combined with Introduction to R.

I suppose it is ok as a foundation. Otherwise, it doesn't offer much on its own.

Not a lot of good information. Just introducing you to the programs being used.

all the content of the course could be a week of some course of specialiazation

Too simple and most contents are overlapped (already covered) in other sessions

Upgrade to submit? That's meaningless. Especially for this fundamental course.

It was good as an introduction , meanwhile its contents are little for 4 weeks

It's way to easy to be a separate course. It should be part of R Programming.

Conteúdo é bom, mas o fato de ser dado por um robô torna a experiência ruim.

This first toolbox module is all about setting up. Not much programming yet.

Decent overview, gave me some things to google. No real substance as of yet.
