The first half of the course is informative and easy enough to follow. However, the last half (which is all about statistical analysis) I feel could have been laid out differently or could have used more practical examples over theory.
Even if you start with the first course in the series of four for the specialization, this course seems to require more background knowledge when it comes to experimentation and statistics if you want to really understand it.
The order in which things were presented was sometimes confusing. For example, there are instances when terminology is defined well-after it has already been used to explain concepts. For example, things like t-tests, p-values, and 'power' were talked about in Week 3 as if they should already be known, only to be explicitly defined near the end of Week 4.
Also, not a huge complaint, but sometimes it seemed like the instructors relied on the presentation slides a little too much; reading word for word and not expanding on it much.
Good information overall, but the teaching could be improved.
