Ideology / Qualification Scores

Martin-Quinn scores measure the relative ideology of a Justice or a Supreme Court term to the median Justice. Andrew Martin and Kevin Quinn wrote an excellent paper about the method.

Segal-Cover scores measure the ideology and qualification of an individual Justice before their appointment to the Court. Jeffrey Segal wrote a summary and shows the raw data as a table (warning: PDF).
