statistical research

i am bored. rather, i was bored just now on a rainy friday morning. was supposed to exercise but i think i'll do that later.

anyway, i decided to categorise my facebook contacts into where i first met them/know them better. exceptions are choir people, i didn't group (most of) them under 'school' categories but 'choir' instead.

my findings:

a few are still unclassified because they're (mostly) friends' friends
10% of friends were from my secondary school choir
10% of friends were from my junior college choir (note that some friends straddle between both sec sch and jc choirs)
10% from primary school
20% from secondary school
13% from junior college

AND!

A WHOPPING 35% FROM NATIONAL SERVICE!

that's like, more than a third of my friends!?

no wonder i have so many facebook contacts, for someone who's quite low profile in school!

now, assuming that my primary school/junior college/jc choir friends consist of an even mix of guys and girls, i would have...

WHAT!?

81.5% OF MY CONTACTS ARE MALE!

ONLY 16.5% OF MY CONTACTS ARE FEMALE!

(that leaves an undecided 2%)

...

ok, because of double counting between my sec sch and jc choir, i'm sure the percentage of guys on my list should be less.

so maybe, 70/30? ( if i add the undecided 2% into the female category - a sad attempt to boost numbers.)

there is gender imbalance in my contacts!

i wonder if this is the case for people who completed NS and were from boys' schools?
