This is a great starter course for data science. My learning assessment is usually how well I can teach it to someone else. I know I have a better understanding now, than I did when I started.

It is a very good course even if you are familiar with some aspects of data science work. If I have to make a suggestion, I would remark the importance of design skills during a data product,

The course content was fine, but I faced some issues with the Quiz content. I don't know if it was browser issue or the website itself, but on my various attempts, the same correct answers were reported as incorrect, occasionally. I had a hard time completing the Data Scientist's Toolbox quiz - despite providing correct answer in the first attempt, it was reported as wrong, and so, I never chose it again. This way, it is frustrating as well as confusing, breaking my confidence, and making it hard for my brain to memorize and recall the correct concepts.

Very informative in a way that I could grasp as a newcomer to Data Science. I had to review a couple of videos to really understand the information, but that was both necessary and worthwhile for a new topic. Relevant examples were also very key especially in the "Defining Success" section, to understand real-world applications. This course is very relevant for my career progression, knowing the nuances and limitations of DS and how to apply in discussion with DS colleagues.

Some very good concepts for newer folks is in place. A good understanding of supervised and unsupervised learning with examples is of help. The trade off between statistics and Data science was interesting to know. More emphasis on tools will allow us to gather a good view of the execution path. But a good insight on the existing tools and what they can do was helpful to know

Very quick and easy to complete. Doesn't go quite as in-depth as I was hoping, but it does say "crash course" right in the title so you can only expect so much. I will be taking more courses on this subject. Overall, even though the information wasn't very detailed, what I learned was very useful, and my research work at my job will improve as a result of taking this course.

The course touches upon most important topics in Data Science but doesn't go deep into the topics:
- Covers most important important topics in Data Science on high level.
- Course works as a "refresher" to follow the course you should know the basics in statistics and modelling. Concepts like parsimonious model would be used with expectation that student already knows it.

Easy, relaxing overview of data science project management. As this is the first class of Executive data science specialization, I give it 4 stars because I believe (or should I say "hope") that someone who is planning to be executive data science manager should know what is statistics or machine learning, or what is the aim of exploratory data analysis.

Quite basic material... If you have some technical background you might fund this course not so useful.
However, I think that it does provide the right information for non-technical managers in a simple and comprehensive way.
Personally, I wish it was a bit longer and deeper to feel like I acquired more knowledge to take it to the next level independently.

Pretty thorough for an overview, and it touched upon most concepts that you'd need to approach Data Science in any meaningful capacity.
My only gripe is with the literal last quiz, wherein no questions were asked based upon the materials, but upon additional PDFs attached to the quiz itself.
You cannot link me 4 PDFs and then claim it's a 4 minute quiz.

I have studied this course as part of the Executive Data Science Specialization. I think this set of four courses meet my objectives by providing a very nice overview on the key points of data science projects. They are good to give a flavor on data science and data science projects helping decide if you want to search for more in depth knowledge.

Great course. Lot of complicated detail segmented and described in a way that was easy to digest. Thoughts for improvement are with the first few segments. The lessons didn't start with the "why". Why machine learning is used or what problem it solved. I had to google that in order to understand before the course which started with "what" it was.

The course is correct. I would like to go a little deeper in each and every aspect of the course. For example, they explain clearly the difference between statistical analysis and machine learning, although, a more detailed examples of when you only can use statistical analysis and when you only can use machine learning is missed.

I really enjoyed this course, it gives me lot of new, interesting knowledge about data science, But there are some mistake about good (clean) programming. Please do not use comments, the comments show strange code, do not write big function etc... Clean code book from Uncle Bob helps me a lot of to write clean, maintainable code.

good, high level introduction what data science is all about. The section on the structure of a data science project could have gone more into details, maybe following the steps on a specific example. I also missed some insight into the step from the question to the search algorithm. Maybe that's part of the further courses.

I learned a lot, the instructors know how to facilitate knowledge but it's not so friendly to people who don't know much about programming, statistics, etc., and there are some grammatical mistakes in the translation to English and some formatting mistakes in some tests. But overall, I'm satisfied with the course.

Quick scope of data science. I particularly liked the discussion about fad versus fact towards the end of the course. Some questions in quizzes seemed a bit arbitrary. The course delivers what it promises; crash-course with the key ingredients for understanding more about what data science is about

A pretty helpful course if one wants to get an idea about what Data Science is. But I was expecting a bit more hands on example in the end. Maybe not a graded part of the course, but still something to give the student a practical idea of how things look like when they are actually doing stuff.

Some of the content and coverage was excellent and others mediocre. There isn't a consistency in the availability of slides that can be downloaded (available for some, not others). Also, when a quiz answer was marked wrong, I would have liked to know what the right answer is for the question.

A good course to start on your journey to understand DS and Machine Learning
I am familar with most of terminology through my experience. My learning is limited because of that but some one new to the filed would definitely learn more. I have taken this as part of Executive Data Science Program

A good primer for aspiring or casual data scientists. I wish it were more technical so I could adopt some assignment solutions for my work, but for one week course the syllabus covered is perfect.
Wish I could save my progress for free to show only to myself that I've completed this course.

Crash course is the correct description; vast amount of material covered in a few segments. As a result, this course is fast-paced and does not go too deeply into any particular aspect of statistics. It is nice to have a little knowledge of the subject matter but it is not required.

I am a PhD biologist leading a team of data analysts. I found this course to be quick and easy to follow, well presented, and extremely helpful. The instructors are truly professional and they excel in this medium, I was very impressed. Thanks Coursera and Johns Hopkins!

It was very good. I am not a DS but have been exposed to their work. I would like to debate whether Hadoop is the best place to do the work today, but the point made still stands. The one thing that made me put a 4* instead of 5: I don't see how it is "executive" yet.

I left with a good understanding of the reach and dynamics of the field of data science. Even with experience in using data to answer questions in the context of an organization this has been a good way of mapping out the areas where that experience can be extended.

A very good intro to Data Science by three experts. Well-paced, with reasonable quiz questions and can be completed in less than a week. However, I would certainly not pay for it, because it is feels more like a well-designed ad for the spesialization that follows!

As advertised. This is a basic introduction into thinking about data science problems and processes. No statistics or coding, but the discussion of tools and ideas will be valuable for anyone who is numerate but hasn't been exposed to data science practices.
