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 great introduction to data science and also to the R Studio environment. R Studio is going to be very used through this specialization, so it is very useful to be familiar with it.

Leveling course to start in the discipline of data science very interesting. It contextualizes in a simple and objective way the necessary tools and environment for a data scientist.

Great Introduction to the tool's we'll need. I like it as a separate class rather than trying to get new tools to work or obtain new material on a timeline during the other classes.

Course teaches how to acquire the tools necessary to complete the Data Science specialization. Explanations were clear, and quizzes and assignments were straightforward to complete.

Es un excelente y necesario curso. Nos da luces sobre las herramientas que deberíamos usar para optimizar nuestro trabajo (en Big Data) tanto a nivel individual como colaborativo.

Don't just rely on the lectures. Use this course to introduce you to a bunch of tools that you'll need when doing data science, and then go study these tools in depth on your own.

Awesome introduction to the field of data science.. good foundations that will definitely take me far as a data scientist contributing more responsively to improved health metrics

A brief but comprehensive fly-over of the specialisation, topped off with some software previews and installations. Bit of practical hands-on and we're good to go. 1 down 9 to go!

This course was a very good intro to Data science for someone coming from a background with little coding experience. The instructors were engaging and assignments were practical.

I had so much fun learning from this course. I think this course has been constructively laid out and the quality of the presented materials are at it best for such a vital field.

Es un curso bastante básico para aquellas personas que nunca han usado la plataforma de Rstudio, sin embargo tiene unos conceptos interesantes que merecen la pena tener en cuenta

This course is very good for somebody who don't have any experience for data handling.I think it gives me much help to let me go another step further in the road of data science.

Good course, but maybe this course and the following course R programming could be combined into an 8 weeks course as that one is took longer than 4 weeks and this one took less.

A great little course, quite basic but very informative if you - like me - do not have a lot of knowledge on the subject. It can be taken in a day if you have some time to spare.

This course was a great start. It was simple enough to follow, I guess the real deal is in future courses. Definitely leaves a good impression for the rest of the specialization!

Overall, a very nice introduction to the basic concepts. Although I've worked with R before, there were still things that I've never heard before (mainly Github and R Markdown).

While this course is basic, it tells everything you need for the following ones. I'd add some more Git basics (other than read their documentation which is indeed a good point).

I found it very much convenient apart from Automated Video lectures. I believe teaching by prof will have much more impact on us. Indeed I liked the course.

Thank you very much.

Class was cool. I have meaning to learn how to use git, github etc. I think version control is very valuable. That is definitely the thing that I got most out of this course.

This course helps to understand the usage of R with RStudio and Git integration with RStudio.

I Recommend this course to all those aspirants who are moving towards Data Science.

Everrything is good but how do I access some links in the video. The PDF files I download, also don't seem to have it. Unless it is a problem with my adobe reader - let me know

I liked very much, brought lots of information according to Data Science. Thanks! I appreciate a lot the first course and preparing myself to participate of the others courses.

Maybe a little slow if you already have some technical exposure, but pretty straight forward and easy to follow if you don't. A well balanced class in my not so humble opinion.
