Answer:
(a) Mean Nodal Degree
The mean nodal degree is a statistic that reports the average degree of the nodes in the graph. This is an useful measure to summarize the degrees of all the actors in a social network.
Nodal degree or degree
of a node in graph theory (useful in social network analysis) is the number
of lines that are incident with it. Equivalently, the degree of a node is the
number of nodes adjacent to it. The degree of a node is a count that ranges
from a minimum of 0, if no nodes are adjacent to a given node, to a maximum of
g - 1, if a given node is adjacent to all other nodes in the graph.
The density of a graph is the proportion of possible lines that are actually present in the graph.
