consistency index

Geology and Earth Sciences
  • In cladistic analysis, a measure of homoplasy in a phylogenetic tree (or cladogram), calculated as the number of steps (i.e. character state changes) in the cladogram divided by the smallest possible number of steps. The index therefore runs from 0 to 1. A low consistency index (less than 0.5) tends to indicate that much homoplasy has occurred.
