First, calculate the difference between each paired observation. Subsequently, it assigns signs to the ranks based on the direction of the difference, ultimately summing the positive and negative ranks separately.
Wilcoxon Signed Rank Table Step Calculation Process
Environmental analysts utilize it to evaluate pollutant concentrations before and after regulatory interventions. The test statistic W equals the smaller of these two sums.
Complementary graphical analyses, such as paired difference plots, often provide valuable context for interpreting results. Finally, compare W to critical values found in the Wilcoxon signed-rank table to assess significance, considering sample size and chosen alpha level.

Understanding the Wilcoxon signed-rank table becomes critical for accurate hypothesis testing and interpretation of results. Fourth, restore the original signs to these ranks.
