The mean axes (in degrees) are shown in the first two columns. Comparisons were carried out for each plane with data from the right-hand, the left-hand, and pooled data in which the left-hand data were reflected about the midline. The Y statistic was computed for each comparison, and its probability under the null hypothesis of common mean preferred axis was computed using bootstrapping (see Methods, Sensitivity model; Fisher, 1993).
