问一道题:NO.PZ2018062016000053

问题如下:

Given the table above, based on the coefficient of variation,which market is least risky?

选项:

A.

Hong Kong

B.

Australia

C.

Italy

解释:

B is correct. A market with lowest CV is the least risky one.

CV(Hong Kong)=20.28/9.2=2.20

CV(Australia)=19.2/10.3=1.86

CV(Italy)=14.72/6.5=2.26

请问这道题的知识点?

居然换答题的顺序,唉。。。

同学你好,

知识点是coefficient of variation,也就是CV,是一种相对的离散程度衡量指标,所以是在方差那个地方讲到的。这个知识点挺重要的,如果忘了需要回去听听视频哈,加油。
