Is really hard to summarize the potential of Data Science and being clear, but I think that the instructors have done their best, so that we can achieve the most from the Course.\n\nGreat Job!

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 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.

Course explanation/class can be a little more simple as this is a crash/basic course for data science. There were multiple situations where I had to google on few data science/statistics jargons, which I couldn't understand as I am a beginner in this field.

While the course has excellent material, I would not send any of my executives to it. The information is to deep and technical for a business executive in my opinion. I would have liked more examples on how implementing this would benefit a business.

Good starting point if you have no idea about what data science is about. It could be more helpful if it made a clearer distinction between classic statistics and data science (it is briefly mentioned); and what are the pardigms of this discipline.

The course was very good. However, there were many terms instructors used in the beginning without explaining them. But later in the course, many of these were explained. However, it always helps to explain any term when it is first introduced.

A really useful introduction to what is data science. I found it very complete, besides maybe I would have liked a little more deepness in some concepts. I'm willing to learn more about the subject, maybe I will complete the whole specialization.

Basic understanding of data science that can help your expectations and realty before entering deep in the data science courses. Recommended for everyone who wish to learn data science or build a data science team to achieve organizational goal.

This is a beautifully designed crash course on Data Science and gives you insight into Machine Learning and how it can be used effectively. The examples it highlights are brilliant! Thanks to the instructors and Johns Hopkins University.

A good start but definitely from the point of view of organizations without a lot of funding. Fortune 100s often don't follow the process as they outlined it because they can afford technologies that don't require data extraction, etc.

Quite fast-paced indeed. Even the instructors seem like they're in a rush :)
It would have helped if there was a glossary of terms for people who aren't well-versed in programming basics.
But in summary, it's an interesting course =)))

I really liked the concepts covered in this course and found the instructors engaging. I felt the course readings were essentially the same as what was covered in the presentations so would probably skip one or the other next time.

Great content. I suggest to improve a little bit the audio quality on the second and third professors, the qaulity of the sound is slighlty lower and makes harder to understand it at high speed for me (no native english speaker)

Extremely helpful and informative this was my first time experience going through an online training, i should say thanks team for making it so easy and effective :-)
Looking forward for more sessions and positive experiences.

Good course with the right level of detail to get your feet on the ground with data science. As an executive learning the Data Science field later in my career I found it to be challenging enough and relevant to my work.

Was a good introduction. The focus was good as I feel I came away with knowledge of the field as opposed to technology. Only recommendation is to ask professors to use more practical examples in the lectures.

Really good quick and dirty high level overview of how to structure and talk about data science projects. Great for improving communication about your project to your boss and people from outside of your team.

This course was truly a crash course with less crashing and more succeeding on the parts of the professors. My only suggestion is to more clearly outline and link the next classes in the specialization.

Questions could have been more difficult. Plus, I'm frustrated that I was taken into a 25-question survey ranking me with other data scientists, but when I clicked out of it I wasn't able to get back.

This course introduced me to the concepts of Data Science and the key words mainly. Some lecturers spoke very fast, and I had listen to them two or three times to keep up with their pace of speaking.

Enjoyed the pace at which the course moved. Teachers were qualified and relevant. Video Production quality could be better, some of the presentation graph were illegible - thus the lack of 1 star.

fairly general concepts of data science, but may be quite helpful l for people totally new to the field of data (e.g. not having any idea), or as material to review the big picture of data science

As questões poderiam ser mais elaboradas.
Ou até mesmo criar mais questões de fixação. Acredito que se o aluno tiver vários exercícios ele conseguirá assimilar mais o material.
