枫下家园 / 望子成龙 / 七年级Report Card上每科成绩都有两栏:一栏是Mark,一栏是Grade Average。Mark是孩子那一科的成绩,Grade Average是什么呢?是不是那一科的全年级平均成绩?谢谢!

say there are 20 students in the class, this mark is the 10th student's mark, not average of total/20

wrong....average is total/number of student, there is one more column called "Median"

先谢谢!就是说那个Grade Average不但不是全年级的平均成绩,连全班平均成绩都不是。而是把全班每个孩子的成绩排名后,居中的那个孩子的成绩。我理解的对吧?还一个问题:你怎么知道的?

logically, shouldn't that be called "Class Avarage" instead of Grade avarage?

;) It should be called "Class Median" :) coz' it's not even the class average. The average is adding up the numbers and divide by how many there are, while the median is the number in the middle of a set of ordered numbers.

标准答案:For Grades 7 and 8, report the grade average. This should be the average of the marks of all students in the school in this grade for the subject /strand.
所以,Grade Average还是指的全年级平均成绩。也就是全年级总成绩除以总人数。
