The average path length is the mean geodesic diststance from any node (album) to any other node in the network.

The median value is the middle value of all path lengths in the network. A median value less than the statistical mean denotes a network that is primarily centralized with outliers skewing the average path length.

The average path length is the mean geodesic distance from a particular band to any other band based upon the connection of albums in the path. For example to move from the band Animals II to Solid Senders, the path length would be 4:

This is the band with the largest average geodesic distance based upon album connections when walking the path.

The Jordan Center of a network are those nodes whose maximum geodesic distances are the smallest found in the graph. In this case, the bands comprising the jordan center share a maximum distance for their particular tree, the value of which is the minimum maximum found. In other words, for every band find the number of steps to the farthest band from it. Take all those maximum values and see which bands have the smallest maximum value and that subset of bands can be considered to be the most central in the network.

The degree centrality measure is based upon the maximal nodal degree of a band relative to its family tree. The 1st level measure is the band with the most bands directly connected to it.

The degree centrality measure is based upon the maximal nodal degree of a band relative to its family tree. The 2nd level is the number of bands within 2 steps (including the bands from the 1st level).

The graph density reflects how interconnected the network is and is calculated by: A complete graph, where every node (album line-up) is connected to every other node, would have a density of 1 while a network with no connected nodes would have a density of 0.

The graph's diameter, otherwise known as the longest link, is the longest path within the network.

A band's career is measured by their earliest recording or release date (if no recording date is available) versus the latest recording date available. Only maximum recording dates are used for a career's upper bound as material may be released well after a band has retired from recording music. This computation does not include solo artists.

The number of members only includes distinct artists, regardless of how many line-ups those artists appeared in.

The number of line-ups only includes distinct line-ups, regardless of any that may have reformed later in the band's history.

Multiple mutually exclusive line-ups are completely distinct from one another. They represent multiple musician composition changes within a band's lifetime.

Contiguous mutually exclusive line-ups are two line-ups which occur in chronological order in the band's recording history that do not share a single member. The band's musician composition has completely changed from one recording to the next.

An artist's career is measured by their earliest recording or release date (if no recording date is available) versus the latest recording date available. Only maximum recording dates are used for a career's upper bound as material may be released well after an artist has retired from recording music.

A clique is a fully connected subgraph. In this case it means that every band in a clique is connected to every other band in the subgraph through a shared member or members. Every artist who was a member of three or more bands creates his or her own clique while the largest fully connected subgraph in the network is the largest set of bands any one artist played in. While it is theoretically possible for a larger clique to exist, comprised of the relationships of more than one artist, the probability of one existing is extremely, extremely unlikely.

Artists who have worked with the most other distinct artists in various bands throughout their career.

Solo artists are considered single member bands and comprise 13.05% of the total number of bands in the network.
