The instructors approach in this course is very cursory. He tries to split the difference in going through the mechanics/mathematical theory and practical applications. As a result, he fails at both. I think it would be better to leave the mathematics and application learning to supporting materials and focus on explaining the theory and concepts of statistical inference in the lectures.

The hardest course I have ever taken! Very hard to follow! Spent a lot of time, trying to understnad the lectures! The final assignment was really good, it really tied everything together! But the lectures and following them was a nightmare and hard to understand! I spent 55 hrs on this particular course! and the last week 4 I spent 20 hrs on this course

The course is very technical and needs a) reading and practice outside of the material presented here and, b) needs you to invest a lot more time than you might believe before you start this course. So if you are looking to just understand the basics of statistical inference or if you don't have a background in statistics then this is best avoided.

This was a difficult course to get through. The lectures were almost completely useless - I had to look up videos from youtube and other sources for every single lecture to learn the concept, and then rewatch the lecture - even then the instructor was difficult to follow. If this wasn't part of the specialization I would have dropped the course.

Good material but the lectures are not well put together for the novice. I think the professor needs to have a little more empathy for the students and not just read notes for the class. Too many sentences with esoteric terms are spewed out without truly trying to explain the material in a way that the student will understand.

this is heavy material, and I suggest it be broken down to two separate courses, and the author take his time in explaining the various concepts in much more detail vs. trying to cram them within 5 or 10 minute sessions. I know I wasn't the only one struggling to keep up with the teacher after week 2.

The content of this course is interesting and i learned a lot BUT it's indeed badly explained, and i lost a lot of time to understand certain things. My advice: watch others videos (from Khan Academy for instance) in order to understand the basics concepts and then, come back to this course.

Sorry to say, but for me as a non-native english speaker, most videos are hard to follow. Its because speaker talks fast, unclean and with bad sound quality. Of course I'm not used to the mathematical english terms. Also the many animations with the slides made it hard for me.

It may be that this is the first Math heavy course in the data science specialisation, but I found this one really hard going, with the videos being particularly hard to follow. I had to do a lot of extra research to find alternative explanations of the concepts involved

Doesn't really teach you stats, gives you a rough idea but only shows you that it's possible in R. Doesn't really explain what it's doing or how to do it, rather "here's a handy R function that does this". Meaning I'm just learning R rather than any actual stats.

True the content is rich, but the instructor is not engaging and much content is not well explained so the learner should search everywhere. If it is to compare with khan academy videos for example, they are much more coherent and way too easier to understand

To someone new to statistics, this course does NOT help. The professor does not seem too interested or enthusiastic and seems like he is reading off the slides. Concepts are not explained clearly at all. Forced myself through this course :(

Despite the pertinent content, the way the instructor gave the classes could have been way more intuitive. You'll find videos on the web that can help you with the subjects covered and do a better job explaining the concepts. Disappointing.

Some concepts are advanced and it requires detailed knowledge of statistics. It would be good to add a chapter to explain the basics before going through advanced concepts. The explanation in some of chapters are very basic.

This course should not be presented by video. I loose lot of time by learn with others supports than Coursera.

Even if I notice and appreciate the works to produce these supports by the teacher, I'm not a big fan at all.

this is a difficult subject that takes a lot of practice to understand. would like to see the course time and materials extended. It would also be helpful to have live online sessions with instructor and classmates.

I think the course was very informative but it took me about 3 months to finish course. Lot of important concepts have been condensed to one or two slides which makes it really hard to grasp the concept quickly.

This course is great, but Brian is certainly not a good instructor. He does not explain things well, and articulate examples. I had to take Statistical Inference from Duke university to pass this course.

This course is poorly taught. The instructors often speed through significant concepts and are generally unable to explain the concepts clearly to someone who does not have a major statistics background.

Taught very quickly and assumes a high degree of math fluency. Only take this if you are either very fluent in math already or have a significant amount of time to devote to understanding the material.

Very poor instruction and organization of topics, very poor explanation of core concepts. I learned more from reading other sources while taking the class than I did from the lectures.

The topics are very interesting and there is no dude that the teacher knows wath he is teaching, even though I think it can be better with more grapics splanations and less formulas.

A lot of the course were not explained in a way that made it easy to understand for a neophyte. I had to go re-watch most of the lessons on khan academy to understand the principles.

professors caffo and leek go way too fast and are completely monotonous. the examples they use assume we know basic stats when likely most of us are a bit rusty.

The class needs to be more accessible especially for non statisticians, I learned more from khan academy which got me through this class than the class itself
