from secondary school till now i don really like mathematics, may be i m not good in logical thinking though. during university life, 1st semester i have to do statistic and mathematic in engineering and sciences, huh, that really was stressing me up... my level of adrenaline (hope that i din get it wrong) getting higher and higher after every class......
my master program also have statistic, but no more calculation like the undergraduates;flipping through the buku sifir and pressing buttons of calculator (casio FX570). now everything i do using software, SPSS, now then i realise the power of statistics. it help us to draw some conclusion from a population by collecting samples from it (*the data collected have to be valid lar in the first place.)
statistics could be divided into two categories: descriptive and inferential. Descriptive is the just giving information about the sample that was observed and inferential statistic would allow us to draw conclusions based on the sample data collected. for example, during Barrack obama's election campaign, we did see percentage of Obama will be the president of America. the expert did not collect samples from all the residents of america, but selectively choose their respondents. from that sample collected, they could make some prediction to it...
hmm.... this data collected is really useful if it was interpreted and provide some information to all the top managers or the management to start a new policy. i m wondering, did our government do the research before taking a decision to have a new policies? especially in education....
