Why the Campaign?

譚校長是在誤導大家嗎?

有學生對我說,譚校長在早前的集會中告訴學生,學校的升讀大專學位比率高達80%-90%。 在我公佈有關升讀政府資助學士學位比率的數字前,我曾將數字電郵給校監要求認證。據知,校監將電郵傳了給譚校長並交由有關老師複核了多天,但未能發現任何重大問題。之後,我才把經核實的數字公開。如那學生所說的話屬實而譚校長又不是在說謊的話,我相信譚校長定是把那些只有超低入學要求的自資學士及副學士課程也包含在他的計算之內,而不是大家一直在討論和關注的升讀政府資助學士學位比率(28.1%)。 所有老師都知道,學校大部份公開試科目均呈負增值。我怎也不能理解,這80%-90% 花言巧語的數字,竟能變成了學校的成就? 註:我孩子就讀的學校的升讀政府資助學士學位比率及升讀大專學位比率分別是70%及100%。 參考:How to Lie With Statistics (1954) – Huff pg 131-142
