A scatterplot representing, for each possible group of each possible size, the degree of weighted concordance against the degree of fineness for the given group. The red line represents the linear correlation line among the two dimensions: as can be argued from the Figure, the two dimensions were weakly correlated (Pearson r=0.13) and the correlation was statistically significant at α=0.05 confidence level (p-value < 0.001)
