A nonparametric test, such as the Mann-Whitney U test or Kruskal-Wallis test, is appropriate for comparing rank ordering of scores as it does not assume normality or equal variances among the groups. Nonparametric tests are also robust against outliers and can handle small sample sizes. On the other hand, parametric tests, such as t-tests or F-tests, assume normality and equal variances and may not be appropriate for comparing rank ordering of scores.
