Ordinal scales are best analyzed with non-parametric tests because they do not assume a normal distribution and only rank order the values without assuming equal intervals between them. However, they are sometimes treated as interval scales, especially in the case of Likert scales, to apply more powerful statistical tests. Nominal scales, which categorize data without any order, are also best analyzed with non-parametric tests, as these tests do not assume any specific data distribution.
