The score for the judicial effectiveness component is derived by averaging scores for the following three sub-factors, all of which are weighted equally:

• Judicial independence
• Quality of the judicial process
• Favoritism in obtaining judicial decisions.

Each of these sub-factors is derived from numerical data sets that are normalized for comparative purposes. For a few countries, comparable data were not available for every sub-factor. In each of these cases, a score was computed for the missing sub-factor based on the country's relative percentile ranking on the other sub-factors.
