LZ 我也知道percentile的意思。 现在看到OG上的这个对于percentile的表述我一直觉得很纠结啊。 OG说的是: the unique height among boys of that age that is greater than or equal to N percent and less than or equial to 100-n percent. 但是我认为应该恰恰相反啊 不是应该the unique height among boys of that age that is less than or equal to N percent and great than or equal to 100-n percent 吗？ 看的我头都痛了。
