Python 16. Exam Statistics -- Misleading Intro

In response to this line:

A very large variance means that the students’ grades were all over the
place, while a small variance (relatively close to the average) means
that the majority of students did fairly well.

A small variance doesn’t say anything about the performance of the students. If there’s a low average and a low variance, they all did very poorly.

I believe it means that they all did well according to the average.

Yes they may’ve done poorly to your standards, but they did relatively well due to the average in the deviation is minimal.
