Statistics for the Verbal section of the Test For Genius - Revision 2004

© April 2010 Paul Cooijmans

The 48 verbal problems in the "Test For Genius - Revision 2004" are a revised version of the former Association and Analogies subtests. A number of too easy or less satisfactory problems have been removed. As a result, the verbal section is somewhat harder than it was in the earlier version.

Because of the extremely high ceiling it is hard to norm the upper part of the range with this number of submissions, the scores clustering together in the bottom half. This probably also depresses the correlations with other tests so far; too few really high scores have come in to see the true behaviour of the harder problems. Their sublime validity however has already been established in the earlier versions of this test.

This section is not used as a test in its own right currently, but the below norms and statistics are informative if one has taken the T.F.G. Revision 2004 and wishes to know how one did on the verbal section.

Correlation with national I.Q.s

Correlation of this test with national average I.Q.s published by Lynn and Vanhanen:

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.
