Statistical inference is the process of drawing conclusions about populations or scientific truths from data. There are many modes of performing inference including statistical modeling, data oriented strategies and explicit use of designs and randomization in analyses. Furthermore, there are broad theories (frequentists, Bayesian, likelihood, design based, …) and numerous complexities (missing data, observed and unobserved confounding, biases) for performing inference. A practitioner can often be left in a debilitating maze of techniques, philosophies and nuance. This course presents the fundamentals of inference in a practical approach for getting things done. After taking this course, students will understand the broad directions of statistical inference and use this information for making informed choices in analyzing data....

Course is compressed with lots of statistical concepts. Which is very good as most must know concepts are imparted. Lots of extra reading is required to gain all insights. Very good motivating start .

The strategy for model selection in multivariate environment should have been explained with an example. This will make the model selection process, interaction and its interpretation more clear.

Caffo clearly knows his stuff. But some of the lectures start off going slow but then take a leap forward into a conceptual realm that is beyond most people if they are not at least somewhat familiar with statistical concepts. Take your time with this one and make sure to do the reading. The videos kind of cut off prematurely sometimes.

Since it is a very theoretical subject, trying to explain it without proofs and plenty of background is hard. But i feel like most of the course is just to memorize formulas without much explanation where they come from. A few examples are computing the expectation and mean of the average distribution and computing confidence intervals.

The course covers very important topics pretty well. The instructors knows the subject, materials are well chosen. However, the lectures could be done much better. There are many typos, the instructor is reading from the slights. Isn't it worth putting a little more effort since this course is taken by the thouthands of students?

The course is good, but not very challenging. Anybody having done any course in statistic would have little to no information from the first two weeks. Only week 4 was interesting to me, dealing with boostrapping.

The teacher is very clear and chooses the subject in a clever way. One always understands what he or she is doing.

Brian Caffo is an interesting lecturer - he dives into the key concepts and ideas that are essential to understanding the statistical concepts necessary to gain a better appreciation of the course. However, presentation and materials need a LOT of work. They can be too overwhelming and most of the times feel irrelevant.

This course should be targeted for Data Scientists, in my opinion it is more for statisticians.

Too much about the insight of statistics and some but not enough about how to use the statistic tools.

Some time the professor seems like he is just reading the slides which I think it doesn't intensive the student.

The course contains a lot I want to learn, but as someone with a limited background in statistics - I found many of the lectures not to provide clear explanations for concepts. I had to use a lot of outside material to try to learn and understand the concepts. The course lectures seem incomplete to me.

The class contents are good I guess. But I don't think the professor knew how to teach and enjoyed the teaching process. Based on my experience, all the concepts are not that hard for everyone if they would be explained in a good way. I finished this course only because I want to do the course capstone.

A good class, but I think there are some missing pieces. For example, there was a lecture on the basics of knitr, but nothing related to creating a pdf from R. In the Regression Models class there is a lecture on basic notation. I think it would have been more helpful to have that lecture in this class.

I really learned a lot in this course, but I find that I got most out of the lectures in week 3/4 when Brian actually stopped reading the slides out loud and explained the concepts i his own words. I believe the course could be improved by taking that approach in the other weeks

The lectures are really hard to understand, while the material itself is really not that hard. The lecturer talks as if he is just reminding us everything we've already learned. Had to go to other MOOC (specifically Khan Academy) to obtain proper understanding of the topic.

The course was very dry compared to the other courses I have taken. Though there was a lot to cover in the four weeks but this was not best way to do it. The course covers a lot of concepts in far too little a time span. It should have been spread into at-least two modules.

To tackle such key concepts and tools of statistics, you need the appropriate time. Too much material covered in this course. I tend to think that revising the approach to this course as two 4 weeks modules would allow to both go more in depth at a more appropriate pace.

ok course. They provide examples that make sense, although assignments don't really touch all of the material covered. The examples as well as assignments tend to be quite helpful, although I dislike how they force the specific format, which for some could be advantage.

This is a decent overview of statistical inference techniques. Make sure you understand each lecture before moving on to the next since they build on each other. The lecture notes are decent but not great. I found it cleaner and easier to take my own notes.

This course was better than the others in the program because there was much less of a gap between the lectures and the graded sections in terms of expectations. Still, I knew this material going in and would not recommend this as a way to learn it.

It felt like there were a lot of jumps between basic statistical formulae and abstractions thereof. While I don't think it was inappropriate for a course on statistics in itself, it felt rather out of place in the rest of the sequence of this course.

The sections on bootstrapping and permutations were great! The instructor does much better, information is easier to follow (better and slower explanations), and the instructor is more engaging when he is not reading from his notes.

The content of the course is really good and so the practices. But the teacher does not know how to explain things and easy subjects are transformed into a difficult ones. I had to study other books to really understand the subject

Although the topic was very interesting, the way of teaching was troublesome. Teacher spoke often in a way as if he talked to specialists. So it was often hard to understand, and for understanding I needed to consult other sources

The subject of the course is very interesting and the professor is very competent. I had the feeling that some subjects were explained in a way that is not very convenient for someone coming from a non-statistical background.

The material in the class is solid, but is poorly described. These are the foundations of statistical analysis, and unfortunately there's a lot of statistics jargon that students aren't going to be familiar with in here.

Nicely outlined and broad in scope, but Brian's presentation is kind of dry. It often appears that he is reading off a script, and sometimes his emphasis on technical details takes away from ease of understanding.

I think the theory is too dense, but with a weak link with R. I understood better with swirl than with the videos. I'd suggest a more organized video with less draws and annotations. They confused me sometimes.

Statistics & Probability being two of the toughest subjects, this course could have been taught a bit more novice friendly way, so that learners with no background in maths can also grab the lectures easily
