The Wilcoxon Signed-Rank test may be more appropriate than the paired-difference t-test if:
A) the population of differences is not normal
B) the population of differences is normal
C) the sample size is small
D) the data values are quantitative
E) the sample size is small and the data values are quantitative
Population of Differences
Refers to the set of differences obtained by subtracting one set of values from another, often used in paired samples analysis.
Paired-Difference T-Test
A statistical method used to compare two related or paired groups by analyzing the differences within each pair.
Wilcoxon Signed-Rank Test
A statistical test not based on parameter assumptions that is employed to evaluate two related samples, matched samples, or repeated observations within the same sample to determine if there is a difference in their population mean ranks.
