NO.PZ2023052302000005

问题如下：

Which of the following statements regarding arithmetic and geometric means is correct?

选项：

A.

The geometric mean will exceed the arithmetic mean for a series with non-zero variance

B.

The geometric mean measures an investment’s compound rate of growth over multiple periods.

C.

The arithmetic mean measures an investment’s terminal value over multiple periods.

解释：

B is correct. The geometric mean compounds the periodic returns of every period, giving the investor a more accurate measure of the terminal value of an investment.

终值是用什么来衡量呢？

嗨，爱思考的PZer你好：


@Yanyee 如果有关键词compound rate of growth；over multiple periods等， 就用几何平均。

嗨，爱思考的PZer你好：


终值就是投资的本息和。可以用能体现出在投资期末全部本息和的几何平均来衡量。

请问终值是一般用几何平均来算而不是用算术平均来算吗？谢谢！
