Wilcoxon Signed-Rank Practice Quiz

Practice the Wilcoxon signed-rank test for one-sample deviations and paired changes. Prerequisites: the sign test, ranking and elementary null distributions. Build absolute ranks, handle zeros and ties, calculate signed sums and normal approximations, and investigate exact sign references, symmetry, resolution and transformation effects. Original scenarios progress from method recognition to diagnostic interpretation, with worked answers and content-based distractor rationales.
