Avis et commentaires pour d'étudiants pour Data Science Methodology par IBM

The final assignment is not very specific. Its's largely open ended and left up to individual discretion. Please make it quiz based or project based, where results are definitive.

The core part of the methodology is not properly covered, it would have been better if the technical information such as tools and the modeling strategies are discussed in depth.

The course was OK but not up-to the Mark,the case study was quite tough to understand,the case study could have been something simpler so that the beginners can understand well.

Using a case study to illustrate the ideas is great. But it will be better if a less complicated example can be used to help following the concepts easier and better understood.

An easier and more relatable case study would exponentially increase understanding. The present one had complex medical terms and added a layer of complexity to the course.

It was very theoretical and, at times, a little boring as well. I was hoping for more of a hands on experience. But it was definitely very instructive and educational.

Since we are following a track, the previous two courses were basic and in this course we came across to lot of data science terminology without proper introduction.

The example provided was not good at all to follow on the concepts. i had a hard time following up with the video since very little time was spent on each concept.

The discussions were too introductory. This would be acceptable had there been links to resources which provided more detailed information on this important topic.

The final assignment is not clear

Data preparation and modeling quite confusing for someone with no prior knowledge in data manipulation and statistical background

Its an important topic for data scientists, but wish it was taught in a more interesting way with multiple examples of different types instead of one case study.

Very short and filled with too much jargons. A much simpler case study would have been great instead of deep diving into the world of Life Science & Healthcare

I found the material here vague and difficult to follow at times. Which led to confusion particularly about what was expected with the peer graded assignment.

Well, when the previous courses in the specialization were a total waste of time, this one is adequate, but still not very usefull for data science itself.

The speaking is too fast and the slides don't help much to follow up the explanation. I found it is better just to read the transcript at my own pace :-)

Better problems (more generalized and relatable) could have been used to describe and make the modules understand better. Not satisfied with this course.

Teaches what it's supposed to but could be more indepth in establishing your understanding of the process of methodology from Analysis to Evaluation

This information is replicated and immersed in the workplace of a data science expert.

In my opinion, there was no need to attend a separate course.

Questions asked during the course videos were repetitive and three of them could not be submitted due to some error, despite trying multiple times.

It's good but I think the case study is not easy to understand and another case study must be included which easily makes you understand this topic

Course was ok. It's difficult to formalize data science into a generic methodology where subject matter expertise is separated from the process.

IBM Developer Skills Network tool is a complete disaster, spending more time trying to get what should have been a PDF than actually studying...

the case study is not easy for someone whos is doing it for first time, also you need more text for explaining the approach analytic.

The topic is super important and interesting. The content of the course was a bit hard to follow. More real-life examples may have helped.

The examples used were poor and the definitions of each stage were not concrete, workable definitions but rather very abstract definitions.
