Pearson correlation.

The table presents the Pearson correlation coefficient between the trajectories of the two principal components computed from each type of whole body pointing in this study. The use of the PCA allowed us to reduce the dimensionality of the space represented by the eight elevation angles. The correlations with the principal components were computed each time between the trajectories of the movements executed over normal durations with either those of the long or short duration movements. The results show that the movements were similar albeit with some small differences.
