The dissent
The most-upvoted critical review (162 votes, 1.0★).
“The speakers gender has absolutely nothing to do with this course, nor should it hold any weight or impact. Knocking and police sirens? Really??”
Coursera's 4.6 comes from 16,563 ratings. Of those, 3.5% 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.
