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.

  • Master the fundamentals and application strategies of the Wilcoxon signed rank test for comparing matched pairs.
  • Recognize scenarios in which nonparametric evaluations are prioritized over parametric analyses.

Final Answer :
A
Explanation :
The Wilcoxon Signed-Rank test does not require the population of differences to be normal, making it more appropriate if the assumption of normality is violated.
