This course is very helpful. It would be a great help if more examples are provided with details on solution steps in line of solving the test questions. Thanks for providing this learning opportunity.

Es un curso, que dependiendo de tus conocimiento estadística será bien fácil, o algo tedioso. Las explicaciones son muy buenas, y es una gran herramienta de repaso de estadística para el uso de datos

the week1 and week2 makes me feel i was a child,it is too easy, but the week4 is good, the example about ball is easy to understand, I think it is worthwell to take in this course if your have time.

Weeks 1-3 were quality. Week 4 was a little sloppy in the instructional videos and less clear than in Weeks 1-3. Overall, concise refresher of various mathematical subjects useful to data science.

The content of the course as a whole is interesting as a good synthesis of basic skills, even though the content of the weeks 3 and 4 lacks of clarity compared to the content of the weeks 1 and 2.

It is very valuable course for data science learners. They provided math topics which required for data analysis. For further learning, it is very useful. Thank you for providing such great couse

Entire course material is very helpful in understanding the concepts.

Only request would be to simplify the probability section a bit more so that it can easy to understand the concepts clearly.

Great refresher and primer. The section on Probability and Bayes Theory needs a lot more support material (video and notes) as it can get tricky and abstract, especially when doing the quizzes.

Good course. The probability portion is very challenging. Dr. Eggers is a tremendous instructor, but I did not feel adequately prepared for the some of the practical application in the quizzes.

Excellent course. Among the disadvantages, I can note that I did not have enough comments on the solutions to the problems that were proposed at the time of testing. More precisely, feedback.

This course was very easy to understand, though I think week 4's context required more examples. Overall, it was a concise course for brushing up basic math skills required for data science.

Good refresher. Weeks 3 and 4 are much more difficult to follow than one and two. Part of this is due to the subject matter but also a change of teacher / and style makes it more difficult.

There are a lot of different topics in this course and I feel that more experimental examples and longer lectures that are more coordinated within the module. It was a good review, however.

Loved it! Started off easy but got a little tricky in the end with Bayes Theorem. Glad I know which data / math areas I need to brush up on for my job. Thanks, Duke University and Coursera!

Well explained concepts most of the time but towards the end, things are harder, and explanations not very detailed along with quizzes that the lessons have not prepared you appropriately.

sometime the lecture is too easy to understand and after some week it goes too hard to understand even it not a hard thing but sometime the lecturer make it so hard so it can make confuse.

A great review of A level statistics which I had long since forgotten but suddenly found myself needing again. A really good balance of work through the weeks and at just the right level.

It started with very basic and gradually it lead me to work more hard and think thoroughly. Quizzes was very good and week 4 was kinda tough for me, but I managed it. It was hard but fun.

It was quite good learning online and it helped a lot to learn Mathematics, I am bit confuse that how would l use this knowledge into data science ? overall reading learning was amazing.

I like all the video lectures more and gives me more ideas to recollect the ideas.. Week 4 videos little more to be improved with other set of examples to make the concepts more clear

Course is really good for beginner who wants to start career with data. Especially is possible understand everything by video companion which explain math skills in practice exercises.

The topics were selected very useful and compact but the videos especially the colors of pen tools that was used during lesson was not suitable and it was hurting somehow to the eyes.

A dificuldade dos últimos questionários (semana 4) não condiz com o conteúdo ministrado em aula, tirando esse detalhe, o curso ajuda a relembrar conceitos de uma forma bastante clara.

I find this course really helpful with explanation of concepts and definitions. I would like the probability module to have more example exercises though. I really need more examples.
