问题如下:
For Year 6-Year 10, the mean absolute deviation of the MSCI World Index total returns is closest to:
选项:
A.10.20% B.12.74% C.16.40%解释:
A is correct. The formula for mean absolute deviation (MAD) is:
Column 1: Sum annual returns and divide by n to find the arithmetic mean () of 16.40%.
Column 2: Calculate the absolute value of the difference between each year's return and the mean from Column 1. Sum the results and divide by n to find the MAD.
These calculations are shown in the following exhibit:
请问平均数为什么不是10个数平均,而是5个数字平均,这是一组return啊?题目有点误导和坑、、、
