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.

Reviews summary

Statistical inference: foundational concepts

According to students, Statistical Inference is a foundational course that is not easy, difficult, and requires a fairly strong background in statistics to follow along. Lectures move too fast and can be confusing. The material is solid and interesting, but it is poorly described and presented as slides with a lot of dense mathematical notation and mediocre voiceovers. Despite the poor presentation, there are many real life examples and the instructor tries hard to improve the course over time.
Content is solid, but poorly presented.
"The material in the class is solid, but is poorly described."
"I started to get familiar with statistical language and satisfied with the course."
"That was what i did actually. I needed to study for a couple of months to have a good understand of this lesson."
Lectures are fast-paced, confusing, and difficult to follow.
"The course covers quite a lot of material, very quickly."
"Awful course with really poor lectures - they are confusing even if you know some statistics."
"The course covers many different topics in the span of 4 weeks from basic probability and distributions to T tests, p values and statistical power. The lectures take the form of slideshows with a lot of dense mathematical notation, small text and mediocre voiceovers."
Recommended for learners with prior knowledge in statistics.
"Unfortunately, the material, while nominally for beginners, requires a decently strong statistics background."
"Too much content for a few weeks, if you don´t have a clue about statistics, It will be hard."
"You'll need to complete this course for the JHU Data Science specialization but you will likely struggle if you don't already have a strong background in statistical inference."
