Positive: 1. Useful topics with practical applications 2. Realistic homework and project 3. TAs and Professor were very helpful. Negative: 1. Instructions for some homework were not clear 2. Grading was rough for some homework, especially for homework that requires visual elements. Overall, I learned a lot from this course. I would like the "coding" session to focus more on the visualization part. Specifically, I want it to show the different types of plots (for that topic, data, and assignments), how to "code" them properly, and when/how we should use them. |
★
★
★
★
★
Too many assignments. It would be better to have less number of assignments, more complex if required. And more time as headsup |
★
★
★
★
★
I got to implement so many things through the assignments and projects in R, though it had been tough initially slowly got to understand everything in detail, overall it was great!! |
★
★
★
★
★
I have learned a lot through this course. Thanks to Professor used the codes to explain the statistic theory and TAs gave us so many help on homeworks. The course workload was heavy. |
★
★
★
★
★
Nthg much Thank you |
★
★
★
★
★
I feel that if exams were included with projects it might have been a good practice for the course. |
★
★
★
★
★
Homeworks were hard, limited extra credit opportunities, no curve in the class. |
★
★
★
★
★
The class is excellently structured, offering engaging and intellectually stimulating content that is thoroughly organized to enhance comprehension. Interactive teaching methods and a supportive environment encourage active participation and open communication. The teaching assistant is incredibly helpful, providing essential support that significantly enriches the learning experience. Thoughtfully designed assignments and projects deeply enhance subject knowledge, allowing us to apply theoretical concepts practically. Overall, the class is skillfully facilitated by a professor who demonstrates deep expertise and a genuine passion for the subject matter, greatly inspiring students. |
★
★
★
★
★
positive - a lot to learn |
★
★
★
★
★
The course is quite fun and has much more practical learning compared to theoretical learning, allowing us to gain hands-on knowledge. |
★
★
★
★
★
At first, I thought it was very hard to survive in this course because of the weekly assignments and stuff but later on it made me flexible enough to accommodate the weekly assignments and concepts easily . |
★
★
★
★
★
I recommend this course to data analysis enthusiasts. The best part about this class is the content it offers and the analytical approach our professor teaches. However, if someone is not willing to work weekly, as this course requires weekly assignments, I would suggest they reconsider, as it honestly requires consistent effort. You will be rewarded based on your work. The first two assignments made me feel lost, but other than those, we should be able to manage as we get all the help we need from the professor and the teaching assistants. |
★
★
★
★
★
Positive thing is I learned a lot while doing this course and it's quite challenging as well.In my perspective I don't have any negatives. |
★
★
★
★
★
The process of learning and the way assignments designed was too good. But, I think the number of assignments are more. Overall great experience. |
★
★
★
★
★
I wanted to take a moment to express my gratitude for your exceptional lectures in our statistics course. Your dedication to teaching and your ability to explain complex concepts have truly enhanced my understanding of the subject. Additionally, I want to extend my appreciation to the teaching assistants for their invaluable support. Thank you once again for your commitment to our education. It has been a pleasure learning from you, and I am grateful for the opportunity to have been a part of your class this semester. |

Excellent course. Learnt a lot from the course in many areas like data analysis, model building etc. Professor's grip on these topics is way beyond our imagination but still his teaching style with practical examples makes it easy for us to understand these topics. Also big kudos to both the TAs for their presence and attention to us every time we needed them. Even now I remember, I was not sure about taking the course coming into this semester. But, now I am glad I didn't drop this course. So big thanks to all 3 of the faculty!! |

In the upcoming week, we hope to get hints on how output looks on our project(milestone 2) as we are trying our best to get the correct result and this would ensure us that we are in correct path. Also if possible please make our final assignment (13) easier or give hints like assignments 7,8,9 as it is the last week for every subject and every subject has deadline/exams this upcoming week. Thank you for taking our feedback into account. |

Every week, I invest time in this course to learn and earn a good grade. However, I face challenges with every homework assignment due to some distracting comments on the table. I believe it's not an effective way to motivate students. I am truly disappointed because my hard work for this course seems to be in vain. |
★
★
★
★
★
I'm concerned the project work can not be done well. |
★
★

Thank you for considering our concerns about TA hours and Assignment deadline extension. Also, thanks for providing hints in R as now we are able to focus more on statistics part of the assignment. |
★
★
★
★
★
The class is good. |
Comments from students |
★
★
★
★
★
Kindly keep the assignment deadlines at end of every thursday i.e. 11:59 pm , instead of 4:00 pm , this would be very helpful if the change is made , kindly consider it. |
★
★
★
★
★
Please do change the TA hours timings in Tuesday. We have other classes in that time. |
★
★
★
★
★
Please reduce assignment difficulty level. |
★
★

I have a class every Tuesday during the TA hours. so can you please shift the TA hours on tuesday to a different day. Thanks |
★
★

★
★
Please reduce assignment difficulty level. |
★
★
★
★
★
Descriptions of questions are unclear. |
★
★
★
★
★
I feel the TA office hours of Ms. Ummey could be on Wednesday or Thursday instead of Friday, so that we could use those hours for the assignment. Also, most of the students in this class are also enrolled in Advanced Numerical Analysis by Prof. Nikolaos and unfortunately the TA hours of Mr. Fettah (11:00 AM - 12:00 PM on Tuesday) clash with the class hours of that class (10:00 AM - 11:30 AM). So we would appreciate a change in office hours of both the TAs. Thanks for the consideration. |
★
★
★
★
★
Thanks the homework hints! It would be better if there were project hints. |
★
★
★

The instruction on hw2 was not clear enough and was too difficult for me. |
★
★
★
★
★
Please include more details in the questions for the homework. The number of assignments is kind-of overwhelming. |

I was a bit confusing at the beginning of the r session what the basic idea or problem we try to address in HW2. But questions from students helped to understand it better. |
★
★
★
★
★
I feel that more R Programming practice needed so that the homework can be done easily. |
★
★

In todays R session we covered content for two weeks. Hope next week we will have more time to explain the content. |
★
★
★
★
★
Looking forward to this |
★

EVERYTHING IS GOOD. |
★
★
★
★
★
Everything was clear! |
★
★
★
★
★
The homework is challenging but useful. |
★
★
★
★
★
I am of the opinion that some more time has to be given to explain and understand R programming so that it would be easy to work on the assignments. |
Comments from students |
★
★
★
★

Hope there was more time to explain the examples where form R studio. |
★
★
★

Class looks good but the lecture was bit hurry |
★
★
★
★
★
Nice class |
★
★

I would like to thank both Professor and TA for their performance and care. |
★
★
★
★

A bit loud and clear voice will make the class more interesting. |
★
★
★
★
★
Everything is good. |
★
★

I learned a lot of basic knowledge of R. Thank you! |
★
★
★
★
★
Great first week with much useful information! However, the R file that the TA showed was not available for the students, which made it a bit harder to follow. Please make it available since it has many useful tips for R & RStudio! |
★
★
★

I think we need to know more details about the project. |
END OF SEMESTER COMMENTS
★
★
★
★
★
Everything is super good Professor has really good grip on what he is delivering and main thing i want mention is about the teaching assistant for this course Kiran Fetah is superb in helping students in all the way they need . Thanks |
★
★
★
★
★
Professor and TA's gave continuous support. I am gonna really miss this class. |
★
★
★
★
★
The most positive thing is conducting TA office hours which is very useful to clarify doubts for solving assignments There is nothing like negative but the deadline time for assignments and project is bit hectic when it comes to the end of the semester though professor and TA worked a lot to give us more time |
★
★
★
★
★
Both Professor and TA's are very supportive and helpful. |
★
★
★
★
★
The topics were explained very clearly and thanks to professor and TA's help, we were able to grasp and solve problems statistically. They are no negative attributes of this class. |
★
★
★
★
★
Too many assignments made me feel a little stress |
★
★
★
★
★
lot of pratical knowledge learnt. overall good subject and good teaching |
★
★
★
★
★
The positive is Professor way of teaching is at top level but coming to the assignments there was a ambiguity between the professor and TA's explanation |
★
★
★
★
★
I really liked the weekly assignment that allow us to apply the concepts we have learnt in class, I like how professor deliver the entire concepts in class using sceneriors and thing we could very much relate to in everyday life. I very much appreciate the effort of the T.A's in ensuring we get the concept and apply them rightly in solving real word problems through their numerous office hours and rapid responses to personal messages on teams. But sometime the assignments get overwhelming. |
★
★
★
★
★
The good thing is that this gave a good exposure to the applications on real world problems. There is nothing much negative but the only thing is the assignments sometimes are challenging. Overall, I feel very glad that I took this subject. |
★
★
★
★
★
I found it awesome about lectures and TA hours It may be some what fair if you can decrease the workload and reduce the difficulty of assignments Also,if you can consider 10 marks as one grade, i would be satisfied in terms of Results. |
★
★
★
★
★
Overall a good learning experience Thanks |
★
★
★
★
★
Positive: Everything goes on in a sequential pattern. Lecture followed by TAs practical session, assignment, Office hours. The grading was on point and punctual. The TAs were very supportive. Negative: The course load was more because of assignments every week. But, that has helped us in learning alot. |
★
★
★
★
★
Positive Attributes: Helps in the way to make sense of the complex data and to make decision. Learned about the assumptions that underline statistical models and the importance of understanding the limitations of these models. Negative Attributes: Difficulty in communicating the results. |
★
★
★
★
★
I thoroughly enjoyed the course and found it to be an enriching learning experience. The course content was well-structured, and the topics covered provided a comprehensive understanding of the subject matter. Throughout the course, I gained valuable insights into statistical methods and their application in research. The practical examples and case studies helped in reinforcing the concepts and made the learning process engaging and enjoyable. I particularly appreciated the emphasis on real-world applications, which helped me relate the material to my own research interests. |
★
★
★
★
★
Classes were informative and we had weekly assignments which was a bit stressful but managed to finish them on time. Each one was a new task and helped me learn new things. Our TA's were very helpful. |
★
★
★
★
★
Negatives are more number of assignments. |
★
★
★
★
★
I learned so much from the continuos weekly assessment and projects from real world data... This course will certainly help me a lot in my career ! |
★
★
★
★
★
Positive:
|
★
★
★
★
★
The course exceeded my expectations in terms of both content and instruction. The professor's, Vitalii's and Fettah's expertise, enthusiasm, and commitment to student success made this an exceptional learning experience, and I am grateful for the opportunity to have taken this course. |

I have some comments on weekly homework as follow: 1- we need rubrics for every homeworks since I missed the same grades for hw1(3 feedback) and hw2 (one feedback)!! 2- we need more details of requirements weekly homework, for example (For the curated PP, HR-E4 and HR-AW signals construct Q-Q plots. The plots should be done for each participant and laid out in the two-page format you are familiar with from Q1 in HW 1. The aim is to provide a comparative and insightful account of signal normality to the analyst. State your observations and thoughts) The solution showed to us in class was in four pages before and After and in Q2 mentioned in two-page! 3- we need the final solution of weekly homework. Thank you! |

Today's class has lot of useful content. Thanks to professor for all the information provided in today's class about assignments and one more chance to makeup for Homework1 |
★
★
★
★
★
Very difficult and time consuming homeworks which require strong knowledge of R programming. Takes an entire week to complete leaving no time for other classes. |
Comments from students |

Unfortunately the online portion had lots of technical problems today, especially towards the end of the first session and continuing throughout Vitalii's demo. The audio would cut out for minutes at a time. I have no complaints about the content, just the stream itself. |
★
★
★
★
★
The calss is intersenting, however I need time to figure out the homework, I sugget to have one week for each homework since I am taking two classes besides this class. Please.. I have one comment to Vitalii please explain slowly since I am beginner in R language. Professor and Vitali and Fettah are doing greet job. |
★
★
★
★
★
I have zero knowledge in R programming and for someone like me I felt the homeworks are very difficult. |
★
★
★
★
★
Dear professor, I had no experience in R language. The pace of class as I felt is fast but I'm covering it up by listening again the recorded lectures. The assignment, I had felt difficult to solve and moving forward since the deadline is fixed at Wednesday, I'm concerned about the course work. Kindly requesting you to be considerate while giving assignments. |
★
★
★
★
★
Good |
★
★
★
★
★
I felt Assignment was too tough. Firstly , I am new to R and as the fisrt assignment was like more than beginners level. So I have a request that if there is any chance of reducing the assignment level so that I can learn from foundations. |
★
★
★
★
★
I felt Homework 1 was too difficult to complete even the deadline was extended because I am not very much aware of R. I kindly request you to decline the level of difficulty if you can so that I could learn from basics. |
★
★
★
★
★
I feel each assignment should have a duration of 1 week to complete them as it is my first time working with R and it consumes a lot of time. And we also have other subjects to work on. |
★
★
★
★
★
The assignment is so difficult it is like i am understanding the topic but when it comes to assignment it is not helping that much. And the assignment is taking a lot of time which is causing problem for my other courses. |
★
★
★
★
★
Please give one week for every assignment |
★
★
★
★
★
Found the assignment somewhat interesting but di... |
★
★
★
★
★
I feel HW01 is very difficult. I have followed the class and office hours but it was so hard for me to get my head around the assignment. If this is the difficulty level for HW01, I wonder how the level of upcoming homeworks is going to be. |
★
★
★
★
★
Hope to extend the work time. |
★
★
★
★
★
The homework 1 was very very difficult and it is taking a lot of time to solve the questions and even the questions are not 100% understandable to do the task. It is even affecting my other courses as i need to spend a lot of time on this course. |
★
★
★
★
★
I felt that Homework-1 was so difficult. As we are new to R we cannot code to that level at the begining itself.I request to reduce the difficulty as the deadline was also a mere 3 days. |

The professor and TA has taught the class really well. The hands on session is very informative, I'd like to name it 'Crash Course on R' |
★
★
★
★
★
Very good and informative session |
★
★
★
★
★
If time permits, I'd recommend a very short introduction to tidyverse, and all the verbs that come with it. Especially the %>% (pipe operator) and dplyr seem very in-use these days. |
★
★
★
★
★
Good session overall |
★
★
★
★
★
The class pace can be bit slowed down for better understanding. |
★
★
★
★
★
As someone who has never used R, I found the intro a bit rushed. However for most it would likely be fine. As we are given the recording, it allows me to rewatch with pause to absorbe it. \nAlso, I like that you are doing this - obtaining feedback early in the class. My first impression is that this will be unlike any university course I have ever taken, in a good way. I'm excited to see all of how it unfolds but from the materials perspective but also from an academic implementation perspective. \nThank you. |

The lectures were easy to understand and carefully explained by the professor including the doubts. The presentations that were saved in the blackboard are used as additional references. The TA explained the concepts and code very well. The marks or assignment evaluations were done very strictly, ie, it is 1 mark less if in one line says 16 and another has 14(by mistake), -1 for report quality. I just hope it would have been much better if it was -0.5 rather than -1. Thanks for all the help. |

Just an awesome class, but I felt that course load(hw) was a bit much |
★
★
★
★
★
The class was very informative and challenging. I learned a fair good deal from this course. Excited to be taking Ubiquitous Computer next fall under Dr. Pavlidis! |
★
★
★
★
★
Professor Pavlidis and the TAs Vitalii and Shaila instructed the course in an organzied manner, providing a learning enviornment encouraging participation and discussion. Weekly homeworks allowed for a steady practice of the information gained from lecture. Labs were extremly helpful in completing homework assignments. Professor Pavlidis provided interesting datasets from the medical field and educational research. Although I do wish I particpated in the in-person course provided due to the unique personalities of the professor and TAs the online form of the course was extremely convinient and useful. |

One of the best classes I have ever taken. Professor: Dr. Ioannis T Pavlidis is the best professor as per me. He is always ready to clear your doubts. Getting responses from him is the easiest task even on weekends which makes him unique among all. If you ask him any questions at any moment, he is very happy and eager to answer everything. His knowledge in the field is beyond the limits. Always listen to the feedback provided by the students. Make necessary changes in class delivery also if students needed (until they are reasonable for sure). Definitely, A LOT to learn from him. TAs: Vitalii and Shaila, are the best at their level. For the practical session, you can always reach out to Vitalii, he is always ready to guide you in the right direction. For any grading, project related queries, Shaila is always ready to give you logically correct feedback. With the help of them, you will definitely learn how to write and organize your code and report. Class quality and workload: Definitely, you will have a huge workload as nothing comes easily. When you have time and want to invest it instead of waste it, surely go for this class. You will enjoy it a lot and will learn a lot. After finishing this class, you will 100% feel that it was useful and all the hard work (ofc smart work is needed 😇😇) that you have done gave you fruitful results. Kudos 🙌🏻🙌🏻🙌🏻 to one of the best teams I have ever worked with. |

The class was very organized and helpful. I have a suggestion for which I might be wrong but I think it will be helpful to all the students: As the end semester is coming and we also have to spend more time on the project milestone 3 if the homework series will become a little bit easier than we can give more time to work on the project milestone. Hope you will consider this. |

It was very disappointing after listening to the feedback from other students. I emailed the professor and TAs during the weekend, and I got all of my doubts resolved. There is no question that can be made about the response, delivery of the class, and the behavior of the TAs if one is attending the lecture carefully and regularly. It is one of the best classes I have ever taken, so no per me the professor can neglect those negative reviews, and I hope he will not think anything wrong with the students who are attending lectures sincerely and doing their job on time. Kudos to the professor and both TAs, they are doing their jobs at the best level. |

Please provide some more detail description in homework. |

The class was interesting. But I think today is the deadline for the project milestone. So, that might affect the overall interaction with the class. |
★
★
★
★
★
A few more hints to assignments would be good. |
★
★
★
★
★
Please be more descriptive in assignments and projects. What's taught in class is not enough to do the assignments. We have to wait till Monday to get clarification on many unclear instructions during the TA session. Vitalii helps us with our doubts but often times what he explains is not what is expected by Shaila. We confirmed with Vitalii that IQR is a good outlier removal method for HW 6 but that wasn't accepted by Shaila. |
★
★
★
★
★
The session was very insightful. The knowledge which I got from the theory and practical session related to the general linear model helped me in working on the assignment. |
★
★
★
★
★
In 6th assignment we followed the inputs per Dr. Pavlidis and Vitali. In the case of removing outliers we removed it after arrivign at a strategy after plotting the data. We removed the data after binding which abs difference is greater 16 as they are outliers. But, we were told this is not a good strategy but were never told which strategy to remove outliers is best suitable for the problem. I hope only way to make it clear would be to announce which strategy would be best suitable for current problem. Please correct me if I went wrong. Thanks. |

The materials covered are pretty intense. However, professor went through the topics at a much reasonable speed. Maybe the methods like BE, FS, etc could be explained in a bit more detail in a more interpretable manner. Other topics were greatly explained. |

The overall lecture is good. TA hours of Vitali is excellent. even he is answering on Sunday also. While this homework series is handling Shaila so Vitali is not going to certain answers as compared to the first homework series. so we asked Shaila for doubts but because of weekends, she might be busy so she didn't give answers to doubts. So it would be very helpful if homework is given by taking into consideration Vitali so students can ask doubts and submit the assignment by the deadline. Assignment complexity is difficult but because of not getting answers from the appropriate TA it becomes very difficult. |

The class is indeed helpful as always. However, I missed some visual plots today. |

I understood the entire class and I have revised the slides also after the class. But what is to be expected from the homework part is quite confusing for me. I am literally struggling a lot with the interpretation of the tests' results. |

Had a better understanding of hypothesis testing. how and what based the data should be tested ( one sided, two sided (alpha)) to determine whether to reject or accept the null and their interpretation. |
Comments from students |

I think Professor is at the right pace but the R programming part is going a little too fast. The TA is doing a great job though, just slightly slow should be perfect. If there is something in the R like Jupyter Notebook, where the code explanations can be put in English, that might be easier too. |

It was an interesting class. Good to know that you have extended the deadline and given us some more time. Quite excellent and ready to help TA. Great work by Vitalii!! |
Comments from students |

It is a lot of information in 3 hours. I think a frequent 5 minute break should be given accordingly so we can process all the information and maybe try a thing or two on our own to completely grasp the concept. The homework is really meticulous and a great practice. |
★
★
★
★
★
Please extend the deadlines for submission of the assignments |
★
★
★
★
★
The topics are pretty interesting. I really like the idea of diving into complex topics slowly. |
★
★
★
★

I think it would be great if the assignments are also allowed to do in teams with 2 members in each team . |
★

Hello, I am content with the way the class is conducted. I like the theory part followed by the practical learning. The assignment was also good, I learned lot new things related to R language and how to do some analysis in it. Thanks, Nilesh |
★
★
★
★
★
The class was good and Lab was very good. This is a new subject for us, the professor should give students some time for assignments and learn R and then submit assignments. else everything is good. |
★
★
★
★
★
The HW is not difficult but a little bit confusing even with the explanations. Could you please make it clearer and easier to understand next time? |
★
★
★
★

Hello Prof and TA, I have no complaints in teaching aspects but it's just if we have doubts in assignment during weekends, we have to wait for Monday (the day of deadline) for TA hours. Is there anything we can do about it? Thank you. |
★
★
★
★
★
The content and the code explanation helped a lot for understanding and completing the assignment. |
★
★
★
★

The session was quite excellent and useful while doing homework. I have one suggestion, it might be wrong but this is what I felt. Homework is assigned in the class, at that moment we are not prepared to make questions. Once we actually implement the script, that moment we encountered more queries. TA hour is on Monday, so we can clear maximum doubts in that session. The best thing is Vitalii was replying on Teams on Sunday also, but it might be possible he is not available. At that moment we might not get enough time to solve our doubts and fix the error in the script. So, I think the management can adjust this thing either by changing TA hour or by giving some more time after TA hour. |

The intro session was good and I liked the immediate responses given by the TAs to the questions raised. But the break in between could be a bit longer in my opinion. |
★
★
★
★
★
The way sessions are conducted that is first starting with some theory and then doing some practical is a great way of understanding the concepts. |
★
★
★

I think the class is good and informative but I feel it is somewhat fast when it comes to R programming according to me. |
★
★

The first session was very informative and haste. I would request you to explain the topics slowly so i can cope up. |

The class is very informative and well-organised. The pace of the class seemed a little fast for me especially the session on R maybe because, I am completely new to R! |
★
★
★
★
★
I felt that the assignment deadlines could be a little extended, and since the class is on Friday, and 3 days for submission will make us work on the weekends, which is okay sometimes but we might me occupied by other things or so. |
★
★
★
★
★
The first class was good, I felt the first class was fast-paced, so maybe in the future session, it would be great if the pace was slowed down a little. |

It's actually good. |
★
★
★
★
★
Overall the class was good, the topics felt very clear. For the practice session, I also was having trouble understanding the block design in terms of commands. I didn't quite understand how Rstudio treats the design as a block without having to specify which variable is your blocking variable. |
★
★
★
★
★
Today's lecture was very helpful as always. The high level information combined with the explanation from the professor was helpful to understand the information, and the example using the MPG data helped me visualize the concept. Additionally, the deeper discussion regarding the project was extremely beneficial for me. |
★

Great explanation. |
★

The class was very interesting and practical experience is very good. |
★
★
★
★
★
I had trouble following along with todays lecture for some reason. I think maybe it was just the speed you went through the slides, it felt like a lot to take in. The Rstudio session was also rushed, but that was understandable since class ran long with the questions. I'm still a little lost on how to do the last portion of the project, but I'm hopeful that we will go into more detail about it in the next lecture perhaps or maybe it will just become more clear as we progress with lecture and the Rstudio practice. |
★
★
★
★
★
Clarifications of the doubts in the class are really helpful and the class is really interesting. |
★
★
★
★
★
Today's lecture was particularly helpful with the lengthy discussion of the figures for the next part of the project. Additionally, the theory for logistic regression was very helpful to understand the concept |
★
★
★
★
★
Things are coming together now. Looks like the 3rd part of the project will be both challenging and fun. |
★
★
★
★
★
Having difficulties to do homework even after reviewed the lecture video couples of times. |
★
★
★
★
★
The class felt a little rushed, but maybe that's just due to it being short. I appreciated the time you took to go over the third and final part of the project, I hope that we can go into more depth as the class progresses I feel like the second portion of the project wasn't covered enough. The example Rstudio session was well done. Going in I wasn't sure what we were doing and by the end I understood enough to do the in-class exercise with some difficulty. |

Overall it was a good lecture, but it was somewhat hard to follow. I couldn't make some of the connections you were making and that may have been helped with examples or maybe not going quite as quickly through the material. |
★

Understood dummy variables. Need to review the second half of lecture again. Class exercise reinforced some of the concepts. |

Everthing's clear and easy to understand and implement. |
★
★
★
★

This lecture was helpful for me to understand the underlying theory of a couple different approaches for linear models, but I had trouble grasping the difference between linear regression and linear modeling in terms of theory. However, the distinction that the application for different factor levels was helpful. |
★
★
★
★
★
Vitali's demo was a little rushed and it was a tad hard to relate it to the exercise |
★
★
★
★
★
I really like the way the class is going including the practical implementation of the topics covered and the time you give at the end of the lecture for the exercise try out. It seems really interesting. |
★
★
★
★
★
It was something new to me, and I think both professor and Vitalii did a great job on the topic! |
★
★
★
★
★
I'm very comfortable with the the lecture and also the practical session provided by the TA. It is very clear and I could clear all my doubts during the session too. |
★
★
★
★
★
I got a little lost at the end with the C(p) portion, but overall it was a great class. I appreciated the time spent talking about the second part of the project and it clarified a few things I was stuck on. |
★
★
★
★
★
Everything is clear and easy to get. |
★
★
★
★

Started understanding multivariate regression and ability to deduce response variable based on their combination. |

The lecture information was helpful and provided enough detail to help me understand the theory behind linear regression without becoming too complicated. The portion of class dedicated to discussion of the second project milestone was also highly appreciated. |

The class is pretty interesting with parallel practical work. |

This was probably the best class to date. I appreciated you going over the project first and taking the time to explain what the plots were. The practice was particularly helpful for the exercise today and sometimes it feels like this is a learn to use Rstudio course more than a statistics course. For example, with the project, which felt very much like a test of how well I could use Rstudio, but today's exercise didn't feel that way. I also appreciated the clear expectations for the second part of the project, so thank you. |

At the end of the class, I'm really happy as I have information about the ANOVA test and how to implement it on some data. For me, it's a valuable class. I appreciate it. |

Thank you for the extension and the hints provided during the class. Is there a chance we can get the answers/explanation for homework 1? |

I had some confusion based on the first project and what was expected from us. The class mostly cleared it up, but having the expectations explicitly outlined in the syllabus or on blackboard would've been helpful, maybe for future classes or for the second assignment if it's not too much trouble. One other thing, in a previous lecture you stated that the third plot was the intersection of the first and second (the lecture on Feb. 05), which made the plot clarification given today confusing since I don't believe that is actually the intersection (I could be mistaken). In any case, it would've been helpful to clarify with more time to fix the plot, again probably something for future classes. Overall the lecture today was good and I learned a lot, I really appreciated detail you both went into during the Rstudio portion of the class. Thank you! |

Overall I think today was a great class. I was a little lost on the discussion about the project and that has me worried that I am somehow behind. But overall I think the length of the class has been better the last two meetings and really appreciate the time in class to do the mini-assignment. |

It'll be helpful if you could explain more about the gephy for the upcoming project. |

very helpful as ur giving the hoemwork realted to the previous class |

The class is very interesting with a parallel practical and hands-on approach. |

The pace of this lecture was good for me and the information provided for gephi and for R for the project tasks was very concise and helpful. |

Great lecture and tutorial. Would it be possible to see the answers for the exercises posted after the due date? I think it would help with the homework a lot. |

As I learn the theory of statistical methods and implement them on R studio , I'm getting more confident to use R programming. |

Today's lecture was very helpful to provide a high-level view of common test statistics and how they are computed and applied. Additionally, the information about the project was helpful for me as well as the R tutorial. |

This class was much simpler to follow than previous portions |

This class was particularly good. I liked that there was time at the end to work on the weekly assignment so we could ask questions if needed. |

Today's class was very usefull. Dr. Pavlidis's lecture moves at a reasonable pace (for me) and tends to focus on important, high level information without going into too much detail about the underlying statistics/mathematics. Additionally, the R tutorials continue to be helpful for me and I find they are paced well |

It's been a good to learn more about the subject, as i get to learn new things and get to know more about the subject. Explaining more in deep would be a better like explaining with more examples would be easy to understand, other than that everything 's fine. thank you. |

Like the material being covered, the real world data analysis project, and practical help being provided by Vitali! I am coming back to school after a while and am a bit rusty with Math. Will covering the stats course at Khan Academy give me enough background to get a solid foundation for this course? |

Informative! |

The class would be interesting if the professor tells us more examples about the theoretical concepts like drawing things on the screen to give us more clarity. |
★
★
★
★

The class was nice and the professor explained everything very nicely. The TA also demonstrate materials nicely/ |
★

I would enjoy it if more in person classes are organised and a parallel on hands experience would do great in the meetings. |

Please reduce the Pace of your explanation and try to conduct atleast a class in-person in a month to revise all the topics coververed so that we can have more interaction. |

Much better today, but the practical portion was still far too quick. I couldn't keep up and it was hard to follow, please try to slow down with the examples, I like to try to understand how the code works and its hard to do that when you skip ahead. |

Kindly, slow down the pace and use as many as examples to demonstrate in practical part of the class. |
★

The lab portion of the class was extremely rushed so it was hard to get anything useful from it. |
★
★

Please provide examples. |

The duration of the class is long, it will become less interesting as time passes. It would be better if the duration of the class is one and a half-hour each on two weekdays. |

I like the way you teach in class. But the pace of the practical class is fast. |
★
★
★

Thank you for your lecture. |
★

The R programming part was very fast. It would be better to cover the basics of each part slowly than to go fast through the whole code. |

Class is helpful for both theory and code sections. Thank you! |

The exercises you worked through at times went too quickly for me, but outside of that the class was very useful. The class itself feels a bit long to be honest, it would've been nice to have two days at one and a half hours or two hours, three just seems like a lot for one time in my opinion, but that could just be me. I really did learn a lot and it was very interesting and I'm excited to learn more. |

Bit of audio problem, but otherwise great lecture. Liked the practical aspect and hands on coding. |

For the break, I would suggest objective time frames so we know how much time we have. Something like "we will take a break until [insert exact time]" would be helpful. Other than that, the lecture was very helpful |

The lecture was informative and a good review on some material I learned in previous courses. |
★
★

I've had no previous experience in R so this was a very good and useful introduction for me. |
★
★
★
★

First lecture was very clear and concise with its goals and content. The R introduction was also extremely helpful and structured very well. |
I am learning more and more.
