〉還是你在暗示年收益上百億的HSBC笨到連個簡單問卷都做不好? 我沒有在暗示任何東西啊。報告最開始有提到這個不是 HSBC 自己做的,他拜託第三方做的, This independent research study is commissioned by HSBC Expat and conducted by third party research company YouGov, who surveyed 9,288 expats through an online questionnaire.
YouGov做的,總共有9288個人參與,報告最末頁, A minimum country sample of 100 expat respondents and at least 30 expat parents is required for that country to be included in the league tables. 最少只要100個人的樣本就可以出現在報告當中,我覺得樣本數太少了,然後並沒有標示出各國的樣本數。
