Brian Caffo's lectures were rambling and confusing, with excessive use of jargon without proper explanation. His graphs were overwhelming with information, and little effort was made to explain the graph. Otherwise, the other lectures were very good, concise, and clear. Thank you.

A good introductory overview of data science. Grounds you on what you can & cannot do with data science. I find defining the question really impactful. Teachers were enthusiastic and the brevity of the course gives it good appeal for beginners who want to "get their feet wet".

Good, simple, straightforward, and applied. It starts to introduce you to the language and platforms of data science, but it is most definitely not a standalone course if you want to be conversant in the field. Really just a "taster" to get you into the specialization.

More lectures but each lecture should be shorter. More examples for each topic would be good.

However it is a crash course, so it is more of an overall description of Data Science, which also gives you suggestions to enhance your knowledge in other courses

This course is pretty basic so don't expect much. Basically this course is more reading than understanding but the articles suggested are good. If you are serious regarding data science then this course may be of not much use to you.

Not all lectures in the course are well done. The one on the data scientist toolbox is good and could have more details. The one separating data science from statistics is too confusing. May need to redo the video on that one.

This course leaves you frustrated, as valuable information is only ad the end and at the beginning. It doesn't really answer questions of what are data science, big data, machine learning, how they interact and how to use them.

Okay content, very mix of level of information. Could state better the terms used in the DS world. The quiz part is not well formed questions, more there to mislead than actuelly verify the knowledge

The course material was good and the presentation was clear, however the Quizzes were very frustrating to figure out when I got them wrong. I could not clearly tell why the answers were incorrect.

I am trying to work out whether or not to get into data science, I thought this would help but still undecided.

I liked the grounding of principles, tools and methods required for the discipline.

The course can use more visuals instead of videos of the face of the instructor. It can also use more interactive examples as this is a more executive view instead of having scholar examples.

Was actually expecting more.

Some of the lectures seemed just to theoretical and distant.

Several of the linked resources do not exist anymore or are accessible only with paid subscriptions.

Great course for somebody who does not know anything about data science. When doing this specialisation there should be credit for those that did the other data science specialisation

Very basic course. If you know about data science, data analysis, or machine learning, you may find this class basic or boring. Good intro course for those who have no prior knowledge

Interesting course but structure was a bit odd I thought, it was not clear why so much time was devoted at the outset to the difference between Machine Learning and data science.

not bad but not good enough for showing examples like data visualization and how to build the mind of data science for several fields (finance, marketing, sales and so on)

I felt that the content of this course was too little. It should go one level deeper and explain the challenges that managers may face when handling data science projects.

The material and lectures are good but the quizes are not very helpful and somewhat random (in answers). The small number of questions make them very unforgiving.

A bit too lengthy for the points to be learnt. Can get more done in less time and fuss. Too many examples especially if one wishes to cover 100% of the material.

Good course, with general and not over-detailed explanations of all the relevant topics in data Science. A good, general overview definitively worth working on.

Pretty high level and quick. Hoping the remaining courses in the specialization give more depth. (Completed this course in an afternoon.)

Lectures were fairly straightforward but not really that exciting and the lecturers sometimes felt a little unprepared or underwhelming.

Interesting course and good learning. However for me some of the video lectures were a little bit unstructured and difficult to follow.

The quality of audio wasn't amazing. Get yourselves better mikes, guys. The language was not properly graded for the beginner's level.
