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 teachers were awesome in this course. I liked this course a lot.Understood it properly.Thanks to all the beloved teachers and mentors who toiled hard to make these course easy to handle.Gracious!

I'm in the data science specialization. Statistical Inference was my 6th course. All of them have been on a spectrum of good to great. But Statistical Inference is a mixed bag for me.
First, if you are thinking about this course, take some time reading the other reviews. I find many of them resonate with my experience leading to 1/5 stars.
One reviewer who gave 5/5 stars said they loved the course. They suggested that other reviewers who gave low ratings are ones that dropped out. I don't find this to be the case. Many of the low rating reviewers actually did pass the course and said very similar things as those who did not pass the course.
Another reviewer enjoyed Brian's dry humour. I must have missed the jokes after watching each video 5 times...
For the record, I almost aced this course. The reason for not getting 100% was because I was so annoyed with one of the quizes that I didn't bother taking it again to correct it. I decided living with 8/10 correct questions was better than having a stroke while in the pursuit of two extra points. Yes, that is how much I hated this course.
The first 2 weeks of the course were the worst. I dropped out for about a month (because of life priorities). Then I couldn't get motivated. 1 month turned into 2 months, then into 3 months. I basically took the entire summer off. Finally I bit the bullet and completed the final 2 weeks. The 3rd week of the course wasn't actually all that bad (though the quiz was terrible). The 4th week felt like the first 2 weeks...terrible.
(By the way, it's a mistake to take such a long break. I had to re-watch the first videos to recall things for the remaining quizzes).
If you don't have some sort of statistical knowledge (or inherent aptitude), be prepared to work four times longer on the course. For all your quiz and assignment time-to-completion estimates, multiply them by 4 or more. Seriously, I spent probably 10 hours on the final assignment which said it should only take 2 hours. Each quiz took me an entire Sunday afternoon (My partner was not pleased).
Now here is where things get awkward. I hated the course .... BUT....I learned things that actually stuck. So in THAT regard, I give this course extra stars. It accomplished something that some University courses could not. I even found myself USING the new knowledge in real world problems. So ironically, is that not a sign that it's ...dare I say...a GOOD course?
Would I take the course again? I actually might, but ONLY because of its place in the overall certification. If you are a prospective student wondering if you should take the course as a standalone course, I don't think I could recommend it, because there are far better ways to learn. In fact, just doing the Swirl lessons could be good enough.
If you are a prospective student and you want the certification, then you'll HAVE to take the course. Why are you even bothering to read reviews?
So I'm giving the course 3/5 stars. If I gave it 1 or 2 stars, my review would be clustered with the majority. If I gave it 4 or 5 stars, I'd be lying.

The content is what you would expect for this subject, but it is not quite presented in a logical and ordered way. The lecturer's style is also very uncomfortable, especially in the first week or two, where it feels like the content is just read (and fast), and not explained on a level expected for a course having no prerequisites. If students don't have any previous statistics experience or knowledge, they would find some of the concepts very difficult, especially as presented in this course, as it appears that the assumption is made that students have a certain level of statistics knowledge already.
I have done the Basic Statistics course on Coursera (University of Amsterdam) and that course takes a more methodical and logical approach to the basic concepts, and if I hadn't done that course already I would have really struggled with grasping the concepts explained in this course. Even having done the Basic Statistics course I struggled anyways, and had to resort to additional information like Statistics for Dummies and various other internet / YouTube videos for more methodical and clear explanations.

This is a great course taught by a clever teacher but...
The content is presented in a very dry, not easy to grasp, manner. In several cases, I had to use external sources to understand the content and/or derive it by myself. When I finally understood the content I couldn't understand why it is presented in such a cryptic manner when the concepts are rather simple to grasp and the math not so advanced.
Professor Caffo is a good communicator in some occasion (the module on Power for example was incredibly well communicated). But most of the time he just throw us some result without properly setting the context and concepts, as if it was understood that we already know most of what he is talking about. (Not the case!)
I plan to make a document that follows the course module and fill in the missing piece of contextual information, derivations and concepts. But this takes a lot of time. If/when it will be completed, I will try to find a way to share it with future generation of students. Because, honestly, the content of this course is not so hard and shouldn't be!

As someone who's new to the world of data science and doesn't have a university degree this course was very hard to get a good grasp on.
That's partly the "cause" of how the course was taught which was assuming you had all the knowledge at hand of all the stuff Statistical Inference is about.
For people that are starting this stuff it might be nice to have a introductory course of Statistical Inference as I did not finish this course by just watching the course video's and additional information, I had to look up additional resources which explained the material better.
Still, a big thank you for explaining statistical inference and opening my eyes regarding this topic, it surely helped getting me to the next step in what Data Science is all about and makes it ever more interesting!

The course is a very quick run through of basic statistics and not very intuitive for people without much statistics/maths background. The swirl exercises is a very good practical learning tutorial that supplements the course, but overall it still lacks on the conceptual aspect. Personally, I have to occasionally refer to other basic statistics materials to be able to follow the flow and understand the lectures.
For the course project, there is a huge discrepancy in what the project expect the students to perform and the peer grading criteria. As a basic statistic course, the correctness of the estimation/ calculation/ assumptions is integral in any analysis but the grading criteria mostly neglect all this aspect. Hopefully the course admin can rectify this aspect of the course.

This is of course my personal opinion, with all due respect for the Tutors. Plus, it has to be noted that I am writing this as a Mathematics graduate, and this course was most probably not meant for people with any background. However, I have seen similar opinions from people like me. Probability calculus and statistics are both enormous areas of mathematics. Introducing them in a 4-week course seems a really bad idea to me. The probability part was in my opinion far better than the statistical, the origin of every new concept was clear. In my opinion, the optimal solution for the course would be to create a separate, longer course in PC and stats and require knowledge of the two for taking Data Science Specialization.

The course is not meant for beginners, but seems to be advertised as such. Knowledge of Elementary Statistics is a must. The course is fast-paced and most people would not be able to finish it in 4 weeks or understand all the concepts in the course without outside help. Use of Discussion Forums and Mentors such as Leonard Greski is invaluable for completing the course successfully. There are several minor flaws in the videos and textbook that need to be addressed. This course would be much better off broken into two (Elementary + Inferential Statistics) and buffered with longer videos and step-by-step instruction and help.
