Relative force differences for individual digits during the transportation of the three different sized posts (all weights combined, n = 192).

Identified here are the proportion of resample cases more extreme than the difference recorded after 100,000 resamples without replacement (one tail). These values are analogous to a significant ‘P’ value, with significant differences (where cases more extreme than the observed difference are under 5% of the distribution) being highlight in bold. Positive values indicate the post detailed in the vertical column to have the greater of the comparative forces, while a negative value indicates the post in the horizontal row to be greater.
