Is fisher's exact test nonparametric

WebNonparametric methods require very few assumptions about the underlying distribution and can be used when the underlying distribution is unspecified. In the next section, we will focus on inference for one parameter. There are many methods we will not cover for one sample and also many methods for more than one parameter.
