>>477 Tables 9 and 10 may be useful in comparing the performance on the TOEFL iBT of a particular student with that of other students from the same native country and with that of students who speak the same language. ETS, creator of the TOEFL test, does not endorse the practice of ranking countries on the basis of TOEFL scores, as this is a misuse of data. The TOEFL test provides accurate scores at the individual level; it is not appropriate for comparing countries. The differences in the number of students taking the test in each country, how early English is introduced into the curriculum, how many hours per week are devoted to learning English, and the fact that those taking the test are not representative of all English speakers in each country or any defined population make ranking by test score meaningless. 翻訳してくれ なんかこのテーブル１０がそうっぽいんだけど、俺には訳せない；；
