It was really insightful, coming from knowing almost nothing about statistics or experimental design, it was easy to understand while not feeling shallow. Just the right amount of information density.

As a business student from Bangladesh who is aspiring to be a data analyst in near future, I love this course very much. The quizzes and assessments were the places to check how much I exactly learnt.

Easy to follow for the most part. A couple of things were outdated so I had to figure them out on my own.

So far so good, Git was a bit difficult to get going but I'm excited to continue with the specialization.

I think more detail statements are needed on PDF.

Because I'm not good at listening, so I studied by PDF.

Quite simple. It could be more engaging.

When downloading PDF slides, links in them should be clickable.
