This is the correlation of raw scores on a test with the national average I.Q.'s of the candidates' countries of origin as published by Lynn and Vanhanen (later Lynn and Becker) in I.Q. and the Wealth of Nations. On average this correlation is slightly above zero. This statistic is abandoned per late 2024 because it has no informational value with regard to particular tests, but it may be of interest in some meta-reports dealing with many tests combined.
