Fig. 6.

A scatter plot, in which each school is a point, indicating the correlation of local assortativities by dorm and matriculation year (x axis) and proportion of nodes which are more assortative by dorm than by year (y axis). For reference, the blue vertical line indicates zero assortativity (random mixing), and the red horizontal line indicates zero difference in $r_{\text{global}}$. Joint distributions of the dorm and year assortativities for four of the schools are shown in the surrounding plots, in which each dot represents a student (yellow = first-year; black = others). Blue lines indicate $r_{\text{global}}$.
