Inferential statistics are concerned with making inferences based on relations found in the sample, to relations in the population. Inferential statistics help us decide, for example, whether the differences between groups that we see in our data are strong enough to provide support for our hypothesis that group differences exist in general, in the entire population.
We will start by considering the basic principles of significance testing: the sampling and test statistic distribution, p-value, significance level, power and type I and type II errors. Then we will consider a large number of statistical tests and techniques that help us make inferences for different types of data and different types of research designs. For each individual statistical test we will consider how it works, for what data and design it is appropriate and how results should be interpreted. You will also learn how to perform these tests using freely available software.
For those who are already familiar with statistical testing: We will look at z-tests for 1 and 2 proportions, McNemar's test for dependent proportions, t-tests for 1 mean (paired differences) and 2 means, the Chi-square test for independence, Fisher’s exact test, simple regression (linear and exponential) and multiple regression (linear and logistic), one way and factorial analysis of variance, and non-parametric tests (Wilcoxon, Kruskal-Wallis, sign test, signed-rank test, runs test)....

Incredibly dense (which they warn you about) so the lecutres fly over so much important info it's hard to keep track of even with a strong focus. A very good overview though.

For people starting out in the field of statistics, this course can be pretty hard. There's a lot going on, the quiz questions are confusing, there are no explanations, and a lot is assumed.

I think this course would have been great if the moderators were still active. There have been no moderator responses in the forums for two years, which means I felt totally without guidance whenever I struggling. A real shame. Also lots of mistakes in formulas and quiz questions - doesn't help matters!!

where to start??

Well, the R Lab tasks are really really great. Except for that, the course is pretty bad. They just spit formulas and formulas and formulas - as if we did not have statistical software to help us - and rarely provide good, objective and clear explanations of concepts and etc. I mean, all the tests assumptions, 'when to use' and benefits are there, but are shadowed by the enormous amount of formulas and statistical tables (all the hard work that we can easily simplify on R or Python, really.

Furthermore, some week quizzers need herculean efforts to complete. Not because they are hard, no. But because if you answer something wrong, you have to do that again, because it doesn't indicate your previous answer. The quizzes also don't explain where you got something wrong and how to solve it (I mean, they say 'check the forum', well good luck with that. I am still waiting for some comments on the post I made on the forum). Furthermore, bad-wording is common on some quizzes and sometimes it is not specified to which decimal place I need to round my results. For real, I failed the week 4 test 3 times because some answer was something like 1.66667 and mine was 1.6667. Please, INDICATE HOW MANY DECIMALS I NEED TO ROUND. This specialization is really good, but this inferential module is really off, especially when compared to the Basic Statistics one.

The instructors are very good, but all those issues really bugged me on this module, hope you guys try to fix it. You are great!!!

Hopelessly fast, compared to the excellent Basic Statistics by the same team. I gave up in week 1.

The course is great, I feel like I learned a lot. One thing that I would have found very useful, however, is feedback on the quizzes — sometimes it is very difficult to figure out what went wrong. This could be implemented by giving people a choice to see some feedback and then no longer being able to re-take a quiz, so people can't cheat but still get positive feedback.

All in all, it's been a pleasure! Thank you very much!

I recommend this course, even though ithere are many subjects you need to learn, exams are very challenging , but you are going to learn. I only think there are some issues in week two and six that there must be improved. For example, english subtitles are not coincident with the teacher is explaining and some examples are not developed step by step.

Excellent course, practical, visual understanding of the concepts and beautifully illustrated of all concepts, definitions and examples. A course that you most take to understand inferential statistics with R as a compliment.

Congratulations to the whole staff that design, produce and teach this course, fantastic !!!!

This course is highly informative and practical in nature and ideal for professionals wanting to gain a deeper understanding of how statistics can be applied in our day to day activities and I would recommend any one out there wanting to pursue this course not to hesitate instead to enroll asbqyickly as possible.

A very very good introduction to Inferential Statistics. A very systematic review of this topic.

I like very much the videos they did, very lively. This is a proof that they have put a lot of efforts on it.

The teachers also give very important remarks to lead us think in the good way.

One of the complex subject is statistics and inferential statistics both are explained in these two courses ( Basic ) and Inferential statistics very clear and to the point no confusion . Thats great and interesting methods are applied during teaching.

Thanks to the Instructors.
