On this page well known quiz statistics (e.g. mean, standard deviation, facility index) are aggregated for a specific question over all question versions in all quizzes. On the versions page (see below) you may also have a look into aggregated statistics for a specific question version."
I am currently testing Moodle 4.0dev+ (Build: 20211102). How do I get to see those aggregated statistics in the Questions bank?
And where is the Versions page?
EDIT.- Just updated my moodle site to Moodle 4.0dev+ (Build: 20211201) and ... the aggregated stats are there!
But... what does "Need for revision = very likely " mean?
