「另外,常犯的錯就是把前、後測是否有顯著差異用two-sample t-test來檢定,不能「假裝」把前測當一組,後測當一組,拿來做two-sample T檢定,而是應該用paired-sample t-test來檢驗是否有差異。」 感謝川爸指正! 2017/9/18 更新:將文章加入副標題,提高可閱讀性,並加入multiple regression、統計分析使用時機的部...

One variable of interest: This is not correlation or regression, where you are interested in the relationship between multiple variables. With a t test, you can have different samples, but they are all measuring the same variable (e.g., height). ...
