Used for norming are the scores from tests correlating .85 or higher. Raw and prior scores, converted to the same scale if needed, are put in two columns of numerical order, the highest facing the highest etc. Norms are obtained by equating the ranks of the raw and prior scores. Scores outside 13 and 108 are extrapolated.

Weighted average of correlations: 0.656

Conservatively estimated minimum g loading: 0.81

Ranking in above table is based on the unrounded correlations. All available data is present in this table, no tests are left out except for those with less than 5 score pairs. All known pairs are used to obtain the true, honest statistics; Correlations are not artificially inflated by leaving out ceiling scores, outliers or other anomalies.

Correlation with national I.Q.s

Estimated g factor loadings Upward and Downward of specific scores

In parentheses the number of score pairs on which that estimated g factor loading is based. The Upward and Downward values are calculated including the pertinent score itself. It is normal that g factor loadings go down when the range is restricted like this, but careful study of the Upward and Downward columns may reveal possible scores below or above which the test loses validity altogether.

Score	Upward (n)	Downward (n)
