Uh... IO.... isn't 50% of the population below any average for that population?
Oh my god! I might have just triggered a multi page discussion about "average" vs "mean" vs "median", and some latin terms I don't know.....
I was taking the micky of a typical Daily Mail (a UK newspaper for the somewhat intellectually challenged) headline which goes something like
SCANDAL: 50% of schools are below average
when of course 50% will be, because that is how "average" is defined.
and as far as I'm concerned he's an idiot, however many flying exams he managed to pass.
You don't need to be bright to pass the PPL exams. The JAA IR exams are no more demanding intellectually but they are a whole lot bigger, to make sure only those really really determined will get through.
