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.

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.

Very very basic, but will get you set up from what I imagine is the more strenuous work to come...

Course contents were good but it had no instructor for the video. Robotic voice was too boring.

You will have to look up updates and a few how-tos on your own in order to complete the course.
