Quizplus · Accepted Answer

The χ2 test (Chi-square test) is a nonparametric test used for categorical data to assess how likely it is that an observed distribution is due to chance. However, the question asks for tests that are not examples of nonparametric methods, making the χ2 test the correct answer because it is indeed a nonparametric method, implying the question might be seeking a parametric method or is phrased to identify nonparametric methods directly. The other options (A, B, C) are all examples of nonparametric tests, which do not assume a specific distribution for the data.
