The number of samples was odd. 27 to be exact. So for the upper quartile it's 3/4* (27+1) = 21th value, which I'm sure was 210.

I hope my stupidity didn't get the better of me, otherwise, as I said, CIE was trying to make amends after that P3 paper by giving us this one. :sneaky:

It was a 5 digit number, no decimals, 65 or 63 thousand something. I don't remember really.

you need for the question to click, it can either take 10 seconds or maybe even ages...
