This is a proper course which will make you to understand each and every stage of Data science methodology. Lectures are well enough to make you think as a data scientist. Thank you fr this course :)

Very informative step-by-step guide of how to create a data science project. Course presents concepts in an engaging way and the quizzes and assignments helped in understanding the overall material.

The example should be easier than CHF in the videos like the example of cuisines was. The CHF example was good but it was not self explanatory and it might be hard for some people.

Great course, but it goes over some key concepts very quickly. It wasn't a problem for me because I'm familiar with statistics and I conduct social science research. But for someone who is completely new to these topics, I think this course would lack enough detail in order to be useful.

Unfortunately, this particular course dissonates a lot from the previous ones made by IBM on Coursera. The material is very poor, the narration is very fast (we're not all native English speakers!) and most of the time it doesn't match what we see on the screen. It's completely confusing, it's impossible to aprehend any information on these videos. The study case is far from a good example to be understood, it only makes the classes even more confusing than they are.
The notebooks are of very poor interaction, and even the quizzes and exams are not pedagogic. I really felt very much frustrated with this particular course and I hope no other will be as bad as this one, as I felt I had just wasted time and money doing it. I really felt like I've learned nothing from it. Reading the "IBMOpenSource_FoundationalMethologyforDataScience" 3 times and then making an exam about it would be 10 times more effective learning than wasting hours on this terrible course.
I am really shocked with the lack of quality of this particular course, comparing to the other which are simply amazing. Please, substitute this course ASAP for a good one, because I am sure it is lowering the overall quality perception of anyone who is following the 9 courses to reach the certificate.
Sorry about the honesty, but it was very hard to go through this course. I am still shocked about the difference between this one and the others IBM has offered.

Actually a really interesting topic but unfortunately made quite poorly. Visuals were complicated, had spelling mistakes and often went at 1 slide / 60 seconds which meant you had no idea which part of the wall of text the tutor was reading. The extremely monotone voice relapsed my attention in the first 10 seconds...

You killed part of my enthusiasm and interest for this Data Science program because of your lame videos, it feels like you went back in the early 90's to make them and the voice is so hypnotic that I couldn't keep my focus, I don't think that I learned much here, I just wanted to go through it as fast as possible.

the main issue with this course is the ibm skills network lab, it have much much errors and lags and to much delay , some times if I closed the tab of the lab i can't reopen it which cause slowdown to my progress in this course and skip many things and labs . Otherwise everything is ok

It's like being taught by a robot. It's just not as effective when the "teacher" doesn't communicate to you like a human. It feels like it was just a voice reading a book to you without proper explanation. As a result this course was unnecessarily difficult to understand.

Not conducted in the way it should be. Too complex to comprehend and difficult to correlate sometimes. Speaker's language was mechanically scripted, boring and non interactive. Important topic barely touched the the surface where deep explanation was required.

More or less a complete waste of time. Some of the Jupyter notebooks were interesting, but not enough to make this anything other than a way to stretch out your enrollment period in the course...

The videos were hectic with information. I felt the need for more explanations or reading material. I am not sure how to apply what I learned in this course.

Prior to undertaking this course, my experience with data science methodology was non-existent. I was not aware of the robust framework developed by John Rollins at IBM, and how it could be used to solve a problem for a business - even if data science was not the end goal. A key lesson from the course as my takeaway would be that it taught me to ask more questions, but more importantly to keep asking questions from different angles.
The course provided me with an invaluable shift in the way that I think about classifying a problem, analysing a problem and then the numerous methods that are available to me when developing a solution.
I would strongly recommend this course even to non-data scientists who require problem-solving tools for their work.
Well laid out, although I do wish that the videos provided a bit more detail on other reading references or articles to gain deeper insights on some of the concepts. (Google definitely helped though).

I appreciate the classes and this whole course. The content is groundbreaking to me! It's such a gift to have learning materials from IBM. Thank you very much.
I like the content but the way it has been ministered/taught could be more dynamic. I like the short and directly-to-the-point videos, but I guess to make comprehension more direct. I mean that if the written information appeared as soon as the speaker mentioned that, it could be more didatic for the student. Sometimes, I didn't know if I payed attention to the written content or to the spoken content. As I am not a native English speaker, for me was sometimes chalenging, thus made me read e watch many times the videos.

Gives the basic understanding of the methodologies involved in data science domain. Outlines the step-by-step stages of the methodologies. Allows you to think like a data scientist for the final project (although not extensively). Didn't cover all the possible models that a data scientist uses on a daily basis. This course tries to explain the things with the help of case studies which consists the basic models and analytical techniques. All the way, this course walks you through the basic fundamentals of the stages in data science methodology.

The course paints an overall picture on the complete set of steps that are followed while working on a Data science project. The best part are the exercises, where we are required to solve a problem to identify the cuisine of any recipe by using a decision tree algorithm. One thing which I found tough was that the python coding part was not explained even a bit. A brief information on the various functions and methods that are used as a part of exercise would be even more helpful. Other than that, its a great course for beginners.

Good course. Thanks to the instructors, IBM and Coursera for making this course available online.
One small thing I would like to request for the answer-input area for the final Peer-Graded assignment. is to provide mechanism to add images and or link as well. That can be very useful for anyone who want to add images of Decision-Tree or Data Model etc. in addition to text explanation to make it more clear. The workaround to load images on Google-Drive and then copy-paste text-link in the answer-box was
okay as well, I guess !!

Best course for starters, really understood key concepts and how to apply them into labs and practice questions. Moreover, this platform really tested my core understanding through the intensity and volume of practice questions (which Cognitive Class only had 3 questions each per practice). Can't wait to get my Badge for this course! One thing is that we learners have to pay access for subscriptions in order to get our certifications and badges which the fees were not mentioned beforehand until before the check-out page.

I would probably give 4.5 stars if there is such choice. Overall, it is good and fun to work through the material but there are places where the message was not crystal clear. For examples, the analogy between data scientist and cook is not always helpful. One of the quiz question described model 2 but was associated with the wrong cost ratio (4:1 instead of 9:1). If Receiver Operation Characteristic (ROC) curve is an important concept then perhaps a little bit more explanation is warranted.

I have previously dabbled in various parts of the full data science process. Including data collection, data understanding and data preparation. I have also separately worked on data modelling and data evaluation on Kaggle. However I am very grateful for this course, as it has enabled me to be able to appreciate the big picture view of data science and has provided me with a framework to use for future data science projects. Insightful and very comprehensive!

I loved this course. I am very new to data science and I was stuck on what is data science and how to start with data science. This course gave me a very good insight right from how to start analyzing the problem and what are the stepped to be followed in each and every stage. The main highlight of this course is they use a case study to explain what happens practically in each and every stage. It helps in properly understading the concepts

I really enjor it. Make me thing as different way in systematic but creative way. There are different ways to solve a problem based on the question we are getting. I know that we only cover some of them for trying not making the course that large. Would be wonderful to have optional resources beyond the course on how to attack different kind of questions as well as evaluating which kind approach use.

The Data Science Methodology really opened my mind to the meticulous process of 'solutioning' as a Data Scientist. Understanding Business Case and what the business owners want, dimensioning to know the approach analytics, knowing the data set to work with and how to analyse same, and ultimately modelling and also learning from the model via feedback so as to make things better.

A quite good course, I like methodology and theory behind data science. I am glad the peer review is 10%, and the quizzes total 90%. I think this helps students to have objective standards and not be dependent on anonymous peer reviews.
Just a little point at the end: The example of the US health care system does not seem to be completely useful for students of other regions.

For the case study presented, specially during modeling and evaluation phases, more elaboration would make the course better. Specially during modeling evaluations and ROC.
Also the course being conducted in a recorded slides is not appealing for student engagement. Would be great to have some videos with people explaining, like in the in course 1 of this program.
