Maria Tencheva completed this course, spending 2 hours a week on it and found the course difficulty to be easy.
The course was very interesting and offered a broad range of different topics. The concepts were introduced in a simple manner in the videos, and then developed further in the pdf documents, which is nice (especially for beginners, who would benefit from examples prior to being given the theory). However, I didn't like how redundant some of the videos were - they are all around 10mins, when the information given can be presented in 5mins maximum. Furthermore, the quizzes are multiple-choice and there are 2 projects (all peer-graded), which might not be the best way to assess this type of course. Overall, great course for anyone interested in statistics and probability!
