Almost all the texture pairs in the \textit{Haptic Textures Ranking} results were statistically significantly different (\chisqr{8}{20}{146}, \pinf{0.001}; \pinf{0.05} for each comparison), except between (Metal Mesh, Sandpaper~100), (Cork, Brick~2), (Cork, Sandpaper~320) (Plastic Mesh~1, Velcro Hooks), and (Plastic Mesh~1, Terra Cotta).

Average Kendall's Tau correlations between the participants indicated a very high consensus (\kendall{0.82}, \ci{0.81}{0.84}) showing that participants perceived similarly the roughness of the haptic textures.

Finally, calculating the similarity of the three rankings of each participant, the \textit{Visuo-Haptic Textures Ranking} was on average highly similar to the \textit{Haptic Textures Ranking} (\kendall{0.79}, \ci{0.72}{0.86}) and moderately to the \textit{Visual Textures Ranking} (\kendall{0.48}, \ci{0.39}{0.56}).
