    列聯表又稱為交叉表,卡方檢定就是要看出Contingency Table當中的實際次數與期待次數之間的差異是否到達一定程度..如我們要測不同性別的付帳態度之期待次數分配表

    圖片參考:http://imgcld.yimg.com/8/n/AC05223625/o/1011060805...

    方格中的數字是觀察次數(Observed frequencies)至於括弧中的數字則是期待數字(Expected Frequencies),又稱為理論次數,也就是在自變項對依變項無影響的狀況下,每個方格數目所應有的次數,它是由總欄數和列總數,皆稱邊緣總數Marginals所交叉決定的
