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 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 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) |
|---|---|---|
| 37 | .71 (274) | NaN (0) |
| 97 | .70 (202) | .69 (24) |
| 117 | .54 (157) | .64 (49) |
| 127 | .13 (127) | .51 (73) |
| 147 | -.11 (88) | .71 (129) |
| 157 | .11 (29) | .74 (194) |
| 167 | .53 (10) | .75 (212) |
| 172 | .42 (8) | .73 (256) |
| 177 | NaN (0) | .71 (274) |
It can be seen in this table that there may be problems with the test's validity in about the raw score range 120 to 160. This is mainly due to the Q.M.C. #4 and to a somewhat lesser extent to Reason (as shown by partly yet unpublished statistics). In an attempt to improve this, revisions have been made to both subtests, the most drastic of which concerning the Q.M.C. #4. The revised version of the R.B.M.C. can be taken even if one has already taken this original version.
See the reports for the subtests Qoymans Multiple-Choice #4 and Reason.
