Thanks

hmm i probably didn't even answer that much of the paper.

but there are alot of smart people on this forum and they put my exam to shame many times over i hope the other 3500 people who sat the exam struggled... more than these guys

You did crap. Go kill yourself to make me look better.

thats above average compared to the state i'd say
most likely in the next standard deviation
good, but not terribly good

huh we dont do gen. math, should we even wat kno standard deviation means? lol

 

[gordo]

one standard deviation above the mean, means u are in the top 85% of the canditure, 2 standard deviations means the top 95% and 3 means the top 1%

the standard deviation for 4u is usually about 18 and the mean about 55 / 120 raw

so if u got above 77 out of 120 raw u will get above 85% aligned, if u get above 95 / 120, u will get above 95% and if u get above 113 / 120 u will get 99%

i think tahts about right
i may have got my bell curve mixed up

You mean, the top 15% and top 5%, or, you beat 85% and 95%.

 

[Kelvy]

don't they mean the same thing...? Unless u mean 85% as a mark and 95% as a mark, and not the amount of people.....

Well, using the number of standard deviations away from the mean of a normal distribution you can work out your rank, or percentile, with some statistics formulae. About 68% of the candidature would be within 1 standard deviation of the mean, 95% within 2 and 99% within 3. Taking what gordo said, that should mean that 68% would have got within 55+/- 18, 95% within 55 +/- 36 and 99% within 55 +/- 54. Hmm, those who got above 110 would be ranked bloody high.
