The dissent
The most-upvoted critical review (67 votes, 1.0★).
“The specialization surely could be improved and these issues corrected, but all courses seem pretty much abandoned by the instructors. Most of the courses still have active "mentors" (volunteers not associated with Coursera nor Johns Hopkins) , but "mentors" seem to have lost contact with the instructors: For example, a couple of assignments require data that is no longer available (dead links) and "mentors" have provided this data in the discussion fora. I reckon that if "mentors" could contact instructors, the dead links would have been fixed in the materials by now...”
Coursera's 4.5 comes from 1,242 ratings. Of those, 4.5% are 1–2★.
Starisk reads the reviews learners voted most helpful, and weights each by the square root of its votes: a review with 80 upvotes counts about five times one with 2. Unvoted reviews are not skipped out of laziness — by this model they carry no evidence that other students endorsed them.
That measures what the most-endorsed reviews say, not “true quality.” The rating distribution above is the whole population, so you can see the sample next to it.
