Can the formal hypothesis testing approach be used for nonparametric tests? How are parametric and nonparametric statistics different? How are parametric and nonparametric statistics similar?
First let us clarify what the formal hypothesis is testing. This simply means that a claim about the data is converted into a symbolic null and alternative hypothesis, next a test statistic is calculated, the test statistic is compared to critical values or a probability is found and a conclusion is reached. The test statistic may be parametric or ...
