網頁前面我們提過了卡方獨立性檢定和同質性檢定的用法，接下來我們來說明卡方適合度檢定( Test of Goodness-of-Fit )，適合度檢定用於分析兩分布的比例是否一致，其說明如下。 一、使用狀況： 欲了解某一變項是否與理論或者是與母體分配相符合。 網頁Chi-square test analysis was used to assess qualitative variables across TPE quartiles. Mixed-effect linear regression models were considered to evaluate associations between TPE (continuous and quartiles) and CVRFs (body composition, BP, glucose, TG, TC, HDL-C, and LDL-C), adjusted for factors previously related to TPE and CVRFs.
網頁The Chi-square test of independence checks whether two variables are likely to be related or not. We have counts for two categorical or nominal variables. We also have an idea that the two variables are not related. The test gives us a way to decide if our idea is plausible or not.

網頁2024年11月7日 · You use a chi-square test (meaning the distribution for the hypothesis test is chi-square) to determine if there is a fit or not. The null and the alternative hypotheses for this test may be written in sentences or may be stated as equations or inequalities. The test statistic for a goodness-of-fit test is: ∑ k (O − E)2 E where:
