Norming method

Used for norming are scores from other tests correlating .44 and higher with the QMC #2. The other scores are converted to the same scale if needed. Ranks of raw and other scores are equated, and there is extrapolation below raw score 4 and above 40.

Correlation with other tests

Weighted average of correlations: 0.379

Conservatively estimated minimum g loading: 0.62

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.

National averages

For reasons of privacy, only countries with 2 or more candidates are included in this table. Ranking is based on the unrounded averages.

Correlation with personal details

Correlation with national IQs

Correlation of this test with national average IQs published by Lynn and Vanhanen:
