The dissent
The most-upvoted critical review (no upvotes, 1.0★).
“Absolutely worthless. The videos and readings are at best shallow and often oversimplified to the point of inaccuracy. The code in the labs is atrocious and provides no useful experience. The multiple choice questions in the quizzes are horribly written.”
Coursera's 4.6 comes from 53 ratings. Of those, 7.5% 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.
