这个跟题目库里面的0-1破产的有什么区别？也是数字区间

  1. CFA I
  2. Quantitative

NO.PZ2021061603000001

问题如下：

Published ratings on stocks ranging from 1 (strong sell) to 5 (strong buy) are examples of which measurement scale?

选项：

A.Ordinal

B.Continuous

C.Nominal

解释：

A is correct.

Ordinal scales sort data into categories that are ordered with respect to some characteristic and may involve numbers to identify categories but do not assure that the differences between scale values are equal. The buy rating scale indicates that a stock ranked 5 is expected to perform better than a stock ranked 4, but it tells us nothing about the performance difference between stocks ranked 4 and 5 compared with the performance difference between stocks ranked 1 and 2, and so on.
