Scatterplot depicting the relationship between the Gold Standard actual accuracy and the degree of fineness when varying the number of involved raters (k) and the reduction employed. For each group size k, the average Gold Standard actual accuracy among all groups of size k was computed. For each reduction, the red line represents the linear correlation between the two dimensions: for all reductions, the two dimensions were strongly correlated and the correlation was statistically significant at α=0.05
