When is it more appropriate to use the Wilcoxon Signed Rank Test rather than the Sign Test?

  • When data is nominal
  • When data is normally distributed
  • When data is ordinal or interval
  • When sample size is large
The Wilcoxon Signed Rank Test is more appropriate to use when data is ordinal or interval because it takes into account the magnitude of the differences between paired observations, unlike the Sign Test which only considers the sign of the differences.
