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.

Not worth the price. Extremely basic stuff spread very thin over too much time just to be able to charge for it.

Useless. The information content is close to zero. Just some blah-blah and a long tutorial to install software.

Way too basic for the price - almost no content - this is just setup - I resent paying for setup instructions.

It's a course which is designed to preview the other courses. It could easily be eliminated

This course could be summed up in one page or so. Very little content.

GitHub lessons good.

The robot voice is terrible. This needs to be fixed. I wish it was an actual person.

I finished this course in one day. It is ridiculous as it is poorly structured.
