问题如下：
Compared to nonparametric tests, parametric tests:
选项：
A.Rely on assumptions regarding the distribution of the population
B.Are used in the situation that there are outliers
C.Can be used when testing whether a sample is random or not
解释：
We primarily use nonparametric procedures in four situations: (1) when the data weuse do not meet distributional assumptions, (2) when there are outliers, (3) whenthe data are given in ranks or use an ordinal scale, or (4) when the hypotheses we areaddressing do not concern a parameter. B and C are suitable for nonparametric tests
什么是used in ordinal scale？
