Medians of sum-squared values of the Jacobians tabulated by category and speaker (left).
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Also shown (right) for each pair of categories, are the number of speakers (out of 5) that returned a statistically significant difference on the Mann-Whitney U test for pairwise differences in medians at the level. (Abbreviations: ISP = Inter-speech pause, Obs = Obstruent, App = Approximant).
