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.

Very easy going, but I think week 3 has much information, maybe a step by step toturial might help.

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