Seems Legit

This was emailed to me by a student earlier today. Thanks to years of training in the mystical arts of the statistik, I am able to pinpoint where exactly these values (the final marks of Polish high-schools students for the year) seem to come unstuck.  You might find it more difficult, of course. Just bear in mind that 30% is the pass mark here.

(This does rather make me wonder if I can get away with something similar in this week's exam board, but I suspect this kind of of shenanigans is harder to pull off when surrounded by mathematicians.)

It's the blip at 100% right? This is clear evidence of right censoring, probably due to their bias against all of the students who also excell at sports and gave 110% to this exam.

I have nothing but contempt for those who merely give 110%. Don't they realise they're only giving 91.7% of 120%? Chumps.
