..不记得原题是什么...但是我觉得下面这段话可以解释到，我表达不清楚，但题目应该是这个意思吧
书上这样写的:
"the media is important becausethe arithmetic mean can be affected by extremely large or small values。When this occurs, the median is a better measure of central tendency than the mean because it is not affected by extreme values that may actually be the result of errors in the date ."
schweser notes..
应该是MODE。The mode is the only measure of central tendency that can be used with nominal data.
