Nonparametric statistical tests are used in research situations in which the dependent variable is measured at which levels of measurement?

A) ratio
B) interval
C) nominal
D) incremental

Nonparametric statistical tests are best used in research situations where the dependent variable is measured at nominal levels of measurement. Nonparametric tests do not make assumptions about the distribution of the data, and instead rely on ranking or categorization of data. Nominal data is the lowest level of measurement, where data is categorized into distinct groups without any hierarchy or order. Nonparametric tests are therefore useful when analyzing nominal data.
