About the Course

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 .

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!
