#Clearly 'Yifei Zhang' has the highest 'betweeness centrality'. Yifei has the degree of "24", which is the second highest in the class. And she has the betweenness(g) of 260.6143603, which is the highest in the class. Therefore, she is the most central person in the course while discussing the p-p network (courses).
