The efforts put in by the lecturers and their knowledge and guidance are admired and respected, however I feel like the entire specialization (all 5 courses) could use ALOT of improvement. I only mention them to help improve and benefit the Lecturers and the 糖心vlog官网观看 community. First the entire specialization could use a lot more visual aid. There are free lectures on Youtube that are much more friendly and animated than the video lectures presented here. I recommend getting rid of the presentation-style of teaching and adopting more modern/animated approaches. (Statistics in general is a field that needs a lot of visual aid)

Moreover, the quizzes (although I understand as someone who takes the quiz I might be biased) should be revised for clarity. This is my personal feeling as some questions feel subjective, and the answers might differ according to different prespectives, some other questions feel a bit irrelevant to the interests of the learner. I don't know if this mimics the green belt certificate exam, but I think this shouldn't be the case for a scientific topic. At least thats the feeling I had answering some of the questions.

Last but not least, please don't make students buy the book, if they already paid for the course. Write your own content.

the course content is good but it is too less specially in DOE section. in DOE there is more than 2 factorial used in real word but it not cover.

Ok theory does not necessarily cover how you can use it in the real world. or the process of using a DOE

It is hard to follow all the possible tests. Maybe that area should be treated at a slower pace.

Slides clearly need improvement. Explanations should not be just a reading of slides.

Difficulty level of video material is very different over this module

Very limited content both in quantity ang depht

exercises with minitab would be helpful

needs more detailed content

More challenge was needed.

Hardest quix ever
