问题如下:
In constructing a chart, using a logarithmic scale on the vertical axis is likely to be most useful for which of the following applications?
选项:
A.The price of gold for the past 100 years.
B.The share price of a company over the past month.
C.Yields on 10-year US Treasuries for the past 5 years.
解释:
A is correct.
The price of gold in nominal dollars was several orders of magnitude cheaper 100 years ago than it is today (roughly US$20 then versus US$1,100 today). Such a wide range of prices lends itself well to being graphically displayed on a logarithmic scale.
