Statistical comparison between 4 classes and post-hoc parwise results for the obtained LDA-derived single feature and its dependence with $\Delta n$ between media and each particle; and particle diameter (d). (a) Results of the Kruskal-Wallis test. Vertical axis is in logarithmic scale. ** $p<0.001$. * $p<0.05$. (b) Graphical representation of p-values obtained in the post-hoc parwise analysis using the Mann Whitney test. Vertical axis is in logarithmic scale. ** $p<0.001$. * $p<0.05$. (c) LDA-derived feature versus $\Delta n·d$, in which d is the particle diameter in meters, and corresponding fit line. Spearman correlation results (two-tailed): $r_{Spearman}=1.00$; $p_{Spearman}<0.05$.
