When you would use a nonparametric test?

When it is uncertain whether the distribution of scores falls along a normal curve OR whether the variance of the test sample represents the variance within the general population. Nonparametric statistics are typically used with NOMINAL DATA, when numbers represent a variable's qualities, and ordinal data, when categories have a definitive order. Examples of nonparametric statistical measure: Chi-square, Mann-Whitney U test, Wilcoxen signed-rank test, and Kruskal-Wallis test.
