Quality of norms: 1.03

Used for norming are all of the known scores from tests correlating .69 or higher with the Genius Association Test (actually the upper nine from the table "Correlation with other tests" below). The used scores are if needed converted to protonorms using the relevant conversion formula or table. The raw scores on the Genius Association Test that form pairs with the used scores are rank-equated to the used scores, and where needed there is interpolation or extrapolation.

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.

Item analysis

Item statistics are not published as that would help future candidates. To detect bad items, answers and comments from testees are studied, as well as, for each problem, the correlation with total score (validity of the item in this test) 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.

It can be said that two problems in this test are still unsolved, while the remaining 58 all have positive correlations with total score.
