Boxplots ¹ of key player values in each of the four networks: Current Collaboration, Powerful, Influential and Well Connected. (a) Normalised indegree (outliers are top ranking central actors); (b) normalized betweenness centrality (outliers are considered the top ranking brokers). Actors marked with ** indicate they are both actual and perceived key players.¹Boxplots show minimum, first quartile, median, third quartile, maximum and outliers shown with star or circle. The stars represent values greater than the third quartile plus three times the interquartile range while circles represent values greater than or equal to the third quartile plus 1.5 times the interquartile range.
