The nonparametric tests discussed in your book (Wilcoxon rank sum test,sign test,Wilcoxon signed rank sum test,Kruskal-Wallis test,and Friedman test) all require that the probability distributions be:
A) identical except with respect to shape (distribution) .
B) identical except with respect to spread (variance) .
C) identical except with respect to location.
D) different with respect to location,spread,and shape.
Nonparametric Tests
Statistical tests that do not assume a specific distribution for the data, often used when parametric test assumptions cannot be satisfied.
Probability Distributions
Descriptions or functions that outline all the possible values and likelihoods that a random variable can take within a given range.
Identical Except
A phrase indicating that objects or scenarios are the same in all aspects except for the specific differences mentioned.
- Differentiate among various nonparametric tests (e.g., Wilcoxon rank sum test, sign test, Wilcoxon signed rank sum test, Kruskal-Wallis test, Friedman test).
