可是我在GMAT PREP 里发现有道题是说。一个班上的全体同学的身高的range是 H centimetre and the highest is G centimeter. 那如果是值域好像就不对了吧,那不就和G一样了吗?这道题让比较的是两个班最矮的是在哪个班。。我觉得这里面range 是平均数之类的吧?
for the students in class A, the range of their heights is r centimeters and the greatest hight is G centimeters; For the students in class B, the range of their heights is s centimeters and the greates height is h centimeters. is the least height of the students in class A greater than the least height of the students in class B?
1.r<s
2.g>h
key: C
i have no idea what does range mean in the context
