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.

Reviews or Test should rely more heavily on the instruction that goes into detail on a topic matter and questions that were asked on quizes. For example, the datasharing question was worth 2 points, when that topic was only cover very briefly.

Although I found the course material in general clear and well-explained, I found the lecture on 'Basic Git Commands' poorly explained and sometimes poorly audible as well. For a non-native speaker of the English language it was hard to follow.

This is a good course for someone who is not familiar with the basics of Git,Github and needs to install R,Rstudio and related packages. If you are not the kind of person described above you will be able to breeze through the course very fast.

The course is very fluent and attractive. You may run into some questions while following the course which you can easily find the answer to by googling it. As a beginner in both Data Science and programming, I'm very happy with this course.

The lectures were good.After all it's robot orienting converstaion it has lot of pace in speech I think that is not good for me.Because It was little bit hard to grasp the message.The pace is only the concerned.Overall lectures were good.

There are some typographical errors in the quizzes and the english subtitles. Not really a big deal. The Week 2 about GitBash made me a little confused because the video about loading git bash happened before the video about installing it.

I don't feel as though the 16 minute video on command lines was efficient. I spent a gross amount of time (over 3 hours) on youtube for supplemental instruction just to complete the final project. Otherwise, this course was sufficient.

A very good course for beginner to start off with. This course really helps setup the fundamental toolkit to create a efficient workflow. The git/github version control linking with R/Rstudio is the best thing I got from this caourse.

Excelent course. The schedule was basic however have approached a thematic complex and important.

The time to complete the tasks week was great.

But I felt need to learn more about git and github. I don't know if it was on follow weeks.

Easy to follow. Might be too easy for some people with experience in data analysis. However, the instructors also talk about some frameworks and insights from their experience which could be helpful for even those who have experience.

El método que sigue el curso me ha sorprendido para bien. Hay determinadas herramientas que aún no comprendo bien qué utilidad podría tener para mí. Quizá porque este primer mes sea muy general. Veremos qué aprendemos este nuevo mes.

Very good composed, explains in a very good manner the complex topic, a general overview about the tools and their connection to each other would be great and helping, as there are many tools to install and understand the functions.

A very good course to learn the different applications needed to start data science. Lectures and examples are easy to understand. Highly recommended to those who would like to know and start a career in the data science field.

The course itself only introduces the main aspects and helps with installation of the tools, while no actual programming is taught. But it is useful for having better understanding of the following courses in the specialization.

Informative course which provides new information in chunks to make it accessible for all. Varied resources to aid all types of learners and regular assessments are helpful in understanding the learning objectives of each week.

Super friendly to new beginners with clear definitions and easy-following learning path. Although a bit of slow for me. I'd recommend anyone without programming background to launch their study in data science with this course.

A nicely designed introductory course of the specialization. Doesn't' have any sufficient value as a standalone course, still, has crucial importance for the thorough and successful study of other courses in the specialization

It is a nice course. From my point of view it would be great if it included more advanced content but I understand that it is an introductory course so it is ok. In that sense it is great for people that is new to this topic.

got a general view of tools that data scientists need to know about or master. really useful and inspiring. this course encourages me to figure out problems I might meet during data analyzing like a data scientist. cheers.

it was hard to find to rewatch to git tutorials, as it was very fractured. Also, hated watching MAC tutorials to get all the vids done. Otherwise useful and well prepared material, looking forward for the rest of the spec.

My first online course and it could not have been any better. Gives me the confidence that I can learn online and add to my knowledge new things. Course material was explained in simple terms which is not the case always.

I think the submission for the markdown file should be allowed to be EITHER an .md file OR an .Rmd file. Seems kind of silly to lose credit for pushing a .Rmd file directly from RStudio rather than saving a text file.

It was a fine overview. I think the suggested text was also okay, but for a $10 suggested price, I would say that there should either be a reading assignment or it should be made more clear that the text is optional.

OK introductory course to the tools used by data scientists, however it's a bit odd this is a standalone course; IMO the course content isn't enough and should be combined with the next course in this specialization.

The class definitely eased a new learner who is unfamiliar with the concepts and skills. There are areas in this class that seemed outdated an made the class a bit confusing. Hopefully, those can be update in time.
