I'm puzzled in my research. In my current project, I need to compare 
two groups of different networks. In Group 1, there are 30 different 
networks. In Group 2, 20 different networks. The average size of the 
first group(nodes around 300) is larger than the second group(nodes 
around 80). 
I calculated the values such as eigenvector and betweenness centrality 
for both groups, and found that these values are consistently larger in 
group 1 than in group 2. How can I interpret the results? Am I 
justified to say that nodes in Group 1 are more central than in Group 
2?  Thanks.
