Fig 3. Cohesion of political groups in terms of RCVs as measured by Krippendorff’s Alpha.

There are two selected policy areas (the left-hand panels), and overall cohesion across all policy areas (the right-hand panel). The Alpha-agreement of 1 indicates perfect co-voting agreement, and 0 indicates co-voting by chance. The overall average Alpha across all nine political groups is 0.7.
