学生对 宾夕法尼亚大学 提供的 Modeling Risk and Realities 的评价和反馈

Nice course, probably the best so far in this specialization. I really enjoyed Sergei Savin's lectures - they were simple & clear. Unfortunately, I cannot say the same for Senthil Veeraraghavan's lectures -he tried to explain an introductory 2-3 months statistics course in just one hour-absolute failure. I definitely recommend the course but I would like to see some improvements in the future sessions with more examples on excel instead of reading mathematical formulas from ppt files.

Please allow Prof. Sergey to take this course. Week 3 was crap because the instructor gave no real-world examples to push home the concepts he was propagating and his english is really hard to comprehend as well.

Some good sections of the course, but others are not explained well at all. Overall valuable material

Awesome couse for learning applications of statistics in real world problems. They show how can we optimize the results using the most common tool among all business environments: excel.

The last week was a quite bit confunsing.

The rest was pretty good!

Pretty Useful

This was a great course; very good explanations teoretical and practice, you gave us powerful tools to analyze data and took the necesary time for cover the topics. Maybe you can add in the future some exercises that we have to upload for review among each other students. Thank you very much for share this tools and your knowledge.

I just wanted to commend Sergei Savin. Throughout the duration of the course he takes his time and explains every step in detail. In addition, he also explains the reason behind what he is doing. I really appreciated the logical approach that he offered. I also wanted to compliment Senthil Veeraraghavan, he did a solid job of explaining the concepts included in the week three sessions. Thank you both!

Useful for business risk analysis and modeling complex problem.

The topics are introduced carefully and several examples are given. Easy to follow.

this is a good course but it's not that informative

Good information on the use of spreadsheets. I had difficulty in Modules 3 & 4 on spreadsheet usage. Could tie instruction closer to quiz questions.

Teacher are good in this season.

I was hoping for more complex modeling techniques.

Great course very interesting. One of the lectures is very hard to understand.

Not too bad of a course. Fairly beginner but there is some interesting things to learn. I would recommend watching the videos at 1.5x speed because they speak fairly slow.

I found useful how to obtain a histogram for discrete distributions. Yet, I think it would have been really important if the professor could have explained more methods to test what kind of distribution the data is related with. All the methods we used relay on know what probability distribution we are working with but if we are not sure which one we have, then the methods would not be as helpful.

Good lecture. Enjoyed the tutorial on binomial distributions

4 starts only because Week 3 lecturer is not good at all. hard to follow, leaves things on slides unexplained. throws bunch of formulas forever without showing it in excel.

Bit of a challenge especially coming down to the end but worth the effort.

This course deserves a 5 star rating because of Prof. Savin but because of Prof Veeraraghavan, I gave it a 3.

Prof Savin's attention to detail and ability to explain complex concepts in a simple way is a gift indeed. He taught week 1, 2 and 4.

Week 3 with Prof Veeraraghavan however, was a different ballgame. Week 3 was an overload of theoretical statistical probability concepts with little or no explanation whatsoever. No explanation on reading chi square tables, no explanation on the calculation of pdf and cdf etc. I was lost when it was time for week 3 quizzes and I gained zero knowledge from week 3.I recommend that Prof. Savin creates a new video for week 3 as I am sure he will teach the courses therein much much better.

the first two lectures are great, but the last two come a little hurry and not illustrate very well

The second lecturer only read all the text in lecture slide.

Only the first lecturer was good. Where are clear excel examples for Week 3, 3.2? You know that students have been complaining over 7-8 months and did nothing! It's a total waste of money.

SERGEY SAVIN is the BEST!!

the quizzes are not really helpful/relevant.
