Good course to give a basic understanding of predictive modelling and analytics. Good assignments and opportunity to review peer submissions help reinforce the learnings.

Even though a basic math background is needed, this course is extremely simplified for understanding and being really useful introduction to Predictive modeling.

This is an important class in data science general and very important in the Data Science curriculum. The class was covering very important concepts and eventually was able to deliver.
However, There were two major issues in this class in particular. One, the instructor’s English was very hard to follow, even with Closed Capturing that sometimes could not convert. As someone that English is not his first language, I can empathize, however there should have been better editing to the videos.
Two, the XLMiner Software we had to use in this class was only available for 15 days trial. This is a 4 week class and by week 3, the trial has expired. I did not plan to buy a license, and they will not extend it by a couple of weeks ( I tried calling both Coursera and Solver.com). And even though any other free tool (Python, R, MS Studios, etc) could have been used they gave different results and was not good for this class. This was frustrating. I ended up signing up for another 15 day trial with another account but that should have never been an issue.

Compared to the first course I felt this one was hard to follow. Information came at a furious pace with little explanation. It reminded me of a business algebra class I took once that had a stand in teacher. The stand in usually taught theoretical match and ended up talking over all of the student's heads. We had to bring him back down to earth. Also the XLMiner tool is only good for two weeks. I verified this with the help desk for the tool. You need better directions and/or a better tool that can be used throughout the 4 week course. Even your translator had issues with some of the annunciations by the instructor. Due to that you need better visuals, explanations of concepts and how he comes around to some of the answers he gets. I really hope the other courses are more like the first and less like this one or I will drop this specialization and go for another. Also I will no longer consider CU Boulder for my Masters.

Not satisfied with the course structure. As you progress in the course, the course seems to be rushed with little detailing. For example the concept of calculating Gini Index. The calculations were not explained and the students are expected to figure it out basis the formula shared in the earlier slide. Had a hard time figuring out the calculation when a problem around Gini index calculation appeared in the Assignment. The accent of the instructor is also hard to understand. Had to refer to transcripts many a times to understand what was been said.

Really good content but the lecturer speaks really fast like reading script ,unnaturally and not communicative but I understand what he speaks, even if the subtitle sometimes goes wrong, however. Peer-Graded system is not productive. I found someone has copied my final assignment, at least should have reviewed my assignment back but did not, really shameless and uneducated. XL Miner on the cloud, for Mac, is free for 31 days with student license, however its interface and process is really time-consuming, perhaps lots of users.

I found the instructor did a very poor job of explaining the concepts he was trying to get across. He read the material as fast as he could and it was obvious. Also, it requires software that has a 2 week license unless you want to pay for it (and this is a 4 week class) or can find ways around it by having multiple email addresses and other ways to trick their system. I don't recommend this course if there are any other options.

Very Poor experience, the instructor was very bad, could not understand anything which he said , this can be seen by the number of [INAUDIBLE] present in the subtitles text. The number of application assignments and the questions were very good , with practice I understood all the concepts and I really think that was very helpful.If the instructor is changed and course content increased , this would be a very good course

I've been struggling horribly with this course. Quite difficult knowledge presented with too little explanation. Much more visual graphs, summaries are needed to explain these data while in the course it is mostly a speech. If pictures are presented, they are without proper description. Whats more the course focus on showing how to do the models, but not how to interpret them.

I really think the lecturer has so much knowledge and wisdom to share with us. But it all goes in vain when students can't understand properly what the lecturer says because of his accent.
I tried very much to understand, it was very hard for me, even with the transcript.
I hope to learn more.

Very difficult to understand, even with CC. The backbone of this course is a little bit of macro handy work from 1995. I am not the most experienced in the field, but i find it hard to believe that any F500 company would use let alone pay for use of that thing.

I would suggest this course to update its video by using text to speech. "The Data Scientist’s Toolbox" is a good example !
too many errors in the scripts, I have posted some on the course forum. some assignments questions not mentioned in the course.

This course requires advanced pre-existing knowledge of statistics to really be of any use. New concepts, formulas and techniques are barely explained but are presented as a 'given'. The course does give you good working knowledge of the Solver tool.

Its really hard to understand the instructor even subtitles mentions inaudible on many places. There should either proper presentations available or Coursera can redraw this course with another instructor

The instructor speak to fast and it's hard to understand what he said too many times. The material in the course in not well done. I believe that the course needs to be remake.

Much below my expectation or the level and quality the other courses bring. There are so many areas within this course that could be improved.

I don't usually rate applications, let alone courses, but this is the one course I was extremely frustrated at, and I saw that I was not alone in this.
First, assignment 3 is buggy, very likely because the version of xlminer is different (I ended up downloading xlminer from other available sources because the version this course gave did not work!!). Different versions including the partition result presentation and logistic regression step 1 appearance.
Second, xlminer is COMPULSORY and NOT FREE (free trial does not count). You can not even use other tools such as Python or R because some of the values asked in questions specifically require excel to get. I still don't get why xlminer can not be a free open source add-ins. Python and R's basic machine libraries are free, why isn't xlminer?
Third, this course is the PREREQUISITE to Advance Business Analytics, which I am more interested in. Combine with my second point, it's like locking a character in a game behind a paywall as a DLC, of course people would not like it.
If you are aiming for a certificate for this course, just forget it, it's not worth it. If you are aiming for learning the subject, you can still take the course. Overall, absolutely not going to recommend it.
To developer of this course, please REVISE THE ASSIGNMENT ASAP.

This class doesn't even deserve that one star.It is easily the worst class I've ever taken on Coursera. The data in the final does not match the description. There are mistakes in the lessons and on the quiz. There is no feedback to forum.I was very disappointed by this course. The professor was knowledgeable, but was difficult to understand and spoke quickly. Even the transcript had the words [INAUDIBLE] listed multiple times because he was so difficult to understand. There were no slides, so note taking was difficult. The course also requires paying $25 for an Excel Add-In, which was not mentioned before enrolling in the course. The Excel Add-In is a different version from the version used in the video, so it was very difficult to follow along because the screens and outputs were different. I also had an issue with the Excel Add-In that made some of my work late because the issue could not be resolved quickly. The Analytic Solver (the Add-Inrepresentative said the problem was on their end, and had to fix the issue himself. Overall I was extremely disappointed and would not recommend this course to anyone. If this had been the first course in the specialization, I would not have continued. In my opinion UC-B needs to rethink if they should even offer this course.
