WebMay 4, 2024 · Hypothesis Testing with Nonparametric Tests. In nonparametric tests, the hypotheses are not about population parameters (e.g., μ=50 or μ 1 =μ 2). Instead, the null hypothesis is more general. For example, when comparing two independent groups in terms of a continuous outcome, the null hypothesis in a parametric test is H 0: μ 1 =μ 2.
