innumeracy
yesterday, i was helping my boss do some analysis with some data (have to be vague here). anyway, i realise some disturbing (but not-so-surprising) misconceptions.
1. ppl who get good scores in a-level maths or engineering maths do not necessarily know wat they studied. i'm not saying ALL who get good scores do not know wat's happening. but rather a majority of them are able to solve exam questions using standard methods without any idea why the methods work. so when they go to work in the real world, they try these standard methods, hoping (and sometimes succeeding) to impress other ppl (who also dunno wat's happening). i wonder how many people really know wat all the t-tests, z-tests mean...
2. ppl think math majors study engineering maths/a-level maths and statistics. the logic is simple. for those who are not engineers only come to contact with maths via statistics. so maths = statistics + a-level maths. for those who are engineers come to contact with maths via engineering maths + stats. so maths = engineering maths (which is advanced a-level maths) + stats. somehow, this logic applies only to math and does not seem to extend to other discipline... anyway, i did only one module on statistics, and it was not even close to statistics. it was on probability theory. so i'm one of those who dunno wat t-tests, z-tests, really mean...
3. ppl think that math majors can solve any problem which has numbers in them. this is like the most irritating thing. ppl like to ask me if i can help to analyse a set of data. huh??? i think a social science major who did two courses on statistical methods can do a better job (assuming that he/she knew wat he/she was reading). then when i say 'i didnt learn this in uni,' they'll respond 'then wat do you learn?' sometimes, i just feel like saying 'things that u'll never comprehend in this lifetime...'
haha. but at the end of the day, somehow, and with some help from google and microsoft, i can do some decent work on the problems... haha. this brings to mind a somewhat arrogant quote from euler (when he solved the 'bridges of konigsberg' problem):
'i do not know why even questions which bear so little relationship to mathematics are solved more quickly by mathematicians than by others.'
heh
