Weighted average of correlations: 0.391 (N = 102)
Estimated g factor 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 3 score pairs. All known pairs are used, including possible floor/ceiling scores or outliers.
Not enough data to make this significant.
| Country | n | median score |
|---|---|---|
| United_States | 14 | 54.5 |
For reasons of privacy, only countries with 3 or more candidates are included in this table. Ranking is based on the medians, and then alphabetic.
Correlation of this test with national average I.Q.'s published by Lynn and Vanhanen, later Lynn and Becker:
| Personalia | n | r |
|---|---|---|
| Disorders (parents and siblings) | 6 | 0.41 |
| Year of birth | 19 | 0.35 |
| Disorders (own) | 6 | 0.28 |
| Sex | 104 | 0.24 |
| Father's educational level | 5 | 0.03 |
| Educational level | 7 | 0.02 |
| Observed associative horizon | 5 | 0.00 |
| Observed behaviour | 5 | -0.12 |
| Mother's educational level | 6 | -0.24 |
In parentheses the number of score pairs on which that estimated g factor loading is based. The goal of this is to verify the hypothesis that g becomes less important, accounts for a smaller proportion of the variance, at higher I.Q. levels. The mere fact of restricting the range like this also depresses the g loading compared to computing it over the test's full range, so it would be normal for these values to be lower than the test's full-range g loading.
| Below 1st quartile | 0.79 (53) |
|---|---|
| Below median | 0.71 (85) |
| Above 51 | 0.48 (99) |
| Above 52 | 0.43 (77) |
| Above 53 | 0.35 (67) |
| Above 54 | 0.35 (67) |
| Above 55 | -0.20 (55) |
| Above 56 | -0.44 (38) |
This table reveals that the test loses its g loading between raw scores 54 and 55. This means that almost all of the candidates have scored in the ceiling (I.Q. 140 when σ = 15) where the test can not distinguish between them.
