Table 2. Cumulative probability distribution of respondent categories represented among the top 20 individuals, as ranked by degree centrality in the knowledge network.

probability distribution†
Owner 13 33 ≥ (<0,00000)
Multi-source client 3 8 ≥ (<0,032)
Client 2 39 ≤ (0,23)
Isolates 2 126 ≤ (0,00000)

†The probability estimate is arrived at by comparing the actual number of actors belonging to a specific category (among the top 20) with the cumulative distribution of actors of that category (that is, the distribution which would be expected if the top 20 actors had been drawn randomly from the entire population).
