    Title: 如何決定抽樣調查中的樣本數

    Abstract: 本文旨在探討如何決定「抽樣調查」的樣本數,因為國內相關研究常有以下問題:(1)沒有報告樣本數量;(2)雖然有報告樣本數,卻沒有說明這種數量的理由;(3)雖然說明了理由,但與抽樣理論不合。因此,本文認為決定樣本數的原則是「求最適」,而不是「求最大」。「最適樣本數」包含了以下觀念:(1)先有正確的研究設計:如果研究設計不好,抽樣沒有代表性,統計會失去一致性,這時樣本再多也無用;(2)符合研究所需精密度:樣本數最好剛好能解答問題,適可而止;(3)要有可行性:要充分衡量調查的經費、人力、時間、設備以及工具,是不是在能力範圍之內。總之,折衷「精密」與「可行」的樣本數,就是「最適樣本數」。
