Weighted average of correlations: 0.082
Conservatively estimated minimum g loading: 0.29
Remark: The very low g loading is caused by (1) the narrow range of scores and low number of effective items resulting from the easy nature of the test, (2) a few bad items, and (3) possible fraud by a small number of candidates (one likely fraudulent score has been excluded here).

Weighted average of correlations: 0.012
Please be aware that correlations with these external tests are in most cases affected (depressed, typically) by one or more of the following: (1) Little overlap with the object test because of the much lower ceilings and inherent ceiling effects of the tests used in regular psychology; (2) Candidates reporting scores selectively, for instance only the higher ones while withholding lower ones; (3) Candidates reporting, or having been reported by psychometricians, incorrect scores.
These are estimated g factor loadings, but against homogeneous tests (containing only particular item types) as opposed to non-compound heterogeneous tests. Although tending to surprise the lay person, it is not uncommon for tests to have high loadings on item types they do not actually contain themselves. Such loadings reflect the empirical fact that most tests for mental abilities measure primarily g, regardless of their contents; that the major part of test score variance is caused by g, and only a minor part by factors germane to particular item types. It is of key importance to understand that this is a fact of nature, a natural phenomenon, and not something that was built into the tests by the test constructors.

Correlation of this test with national average I.Q.'s published by Lynn and Vanhanen:
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 both values to be lower than the test's full-range g loading.
Raw score | Upward g (n) | Downward g (n) |
---|---|---|
0 | 0.29 (144) | NaN (0) |
33 | 0.32 (139) | -0.58 (3) |
35 | 0.20 (96) | -0.36 (65) |
37 | 0.61 (34) | 0.30 (89) |
42 | NaN (0) | 0.29 (144) |
Remark: This low reliability (and therefore large error of measurement) is mainly caused by the fact that many of the test's items were never or rarely missed, so that the test effectively had fewer items that it seemed (a shorter test has lower reliability). This can also be understood when looking at the narrow range of scores. There were also some bad items, which have been revised before inclusion in the Revision 2011 of the test.
Reliability puts an upper limit on the test's possible (true, significant) correlations with other tests, and thus this low reliability also causes the test's g loading to be low.

Remark: The quality of this test is so low that it is probably better not to include it in studies related to high-range I.Q. tests, and for this reason the test has from 2011 to late 2014 been disabled in the database. It has been activated again to allow generation of the statistics in this report, and thus allow comparison with the revised version which has its own statistical report.
Item statistics are not published as that would help future candidates. To detect bad items, answers and comments from candidates are studied, as well as, for each problem, the correlation with total score and the proportion of candidates getting it wrong (hardness of the item). Possible bad items are removed or revised, resulting in a revised version of the test.
