1430. Which is not correct about non-parametric test of significance?

Correct Answer: Correct answer is: (D) They make strong assumptions of homogeneity of variance of the groups to be compared.

Exam Relevance: GRE, GMAT, PhD Qualifying Exams, Biostatistics Exams

Difficulty: Moderate

Concept notes: Non-parametric tests do not assume a specific distribution for the data and are often used when the assumptions of parametric tests are not met.

Common Mistakes: Students may incorrectly assume that non-parametric tests require strong assumptions about the data, such as homogeneity of variance.

Explanations: Non-parametric tests are distribution-free and do not assume a specific distribution for the data. They are often used when the assumptions of parametric tests, such as normality and homogeneity of variance, are not met. Therefore, non-parametric tests do not make strong assumptions about the homogeneity of variance of the groups being compared.

Option Analysis:

Option A: Non-parametric tests are indeed distribution-free, meaning they do not assume a specific distribution for the data.
Option B: Non-parametric tests can be used with small samples, but they are not exclusively small-sample tests.
Option C: Non-parametric tests compare population distributions rather than specific parameters, such as means or variances.
Option D: Non-parametric tests do not make strong assumptions about the homogeneity of variance of the groups being compared, making this statement incorrect.
