Rank-order tests, such as the Mann-Whitney U test or the Kruskal-Wallis H test, require the use of nonparametric tests for analysis. These nonparametric tests are generally less familiar to many researchers compared to parametric tests, which are typically used with data transformations aimed at normalizing distributions. This is a distinct disadvantage of rank-order tests, as it may limit their use or interpretation by those not accustomed to nonparametric methods.
