中文摘要 | 樣本代表性是調查研究者所關心的問題,而適合度卡方檢定的顯著水準也一直被 用作衡量樣本代表性的指標。然而,這樣的指標卻與樣本大小成正比,並隨著樣本增加而愈 容易達到顯著。 本文提議採用 Cohen (1969) 所使用的適合度作用大小指標 e,取代 X �� 作為檢定樣本代表性的指標。文中並舉出一些應用 e 指標的法則與實例,以茲參考。 |
英文摘要 | Survey researchers have long been concerned for sample represent- ativeness, and have been using chi-square of goodness-of-fit to test it. However, chi-square value is proportional to sample size and, other things being equal, becomes more significant as sample size increases. This paper proposed the adoption of Cohen's (1969)e, which had been used as an indicator of effect size for chi-square tests of goodness-of-fit, to replace X �� as an indicator of sample representativeness. Some rules of thumb and examples of using e were also provided. |
