我的發現

一、利用所釋出程式碼復刻出來的圖形與文獻內容不同

依照著作者所釋出的程式碼執行，發現圖形顯現出的變數與文章內的有所不同，應該是作者後來有依照自己想看的進行調整，發現他所興趣的潛在關連後進行文章寫作。

二、我所發現有趣的潛在關連

下圖一為依照作者釋出的程式碼所得到的圖片（未調整），可以發現到選擇綠茶(green)與晚餐會喝茶(dinner)在第二維次上位子幾乎重疊，且在第一維次上的距離也相距不遠，代表吃晚餐會喝茶的人與會選擇綠茶間具有潛在關連性，是否意味著晚餐時人們會選擇鹼性較高可以去油的綠茶，來緩解食物所帶來的油膩。

圖一、依照程式碼執行的結果

下圖二為作者在文章中所用的圖片，其中我發現人們在午餐後選擇喝茶(after.lunch) 與選擇喝綠茶(green) ，一樣在第二維次上位子幾乎重疊，且在第一維次上的距離也相距不遠，代表吃午餐後會喝茶的人與會選擇綠茶間具有潛在關連性，是否意味著午餐後人們也會選擇鹼性較高可以去油的綠茶，來緩解食物所帶來的油膩

圖二、作者文章中所呈現的圖片

結論：飯後人們喜歡綠茶解膩

雖然這份資料並非台灣的研究，但在台灣飲食習慣上，的確許多人會喜歡在吃飯或飯後喝綠茶來解膩，然而從作者的研究資料發現，在國外人們午、晚餐也會有喝綠茶解膩的習慣，雖然地區、國家、文化不同，但也許可以針對此現象研究西方喝茶文化，是否會受到東方茶葉西傳時的習慣影響作研究，可以更深入瞭解西方喝茶文化與東方的關連性。

課堂發現

從圖中發現employee(雇員)與slimming(減肥)變數幾乎重疊，代表兩者存在著潛在關聯。

也就是說上班族喝茶在意的是減肥效果，因為上班族是屬於低勞動工作，在辦公室生活中消耗熱量較少，因此希望透過喝茶在日常飲食中，達到控制體重的效果。
