Used for norming are scores from tests correlating .58 or higher with the Numerical Insight Test. The used scores are if needed converted to an IQ scale with a standard deviation of 15 [March 2008 the IQs were converted to protonorms using the initial protonorm formula]. Raw scores on the Numerical Insight Test are rank-equated to the other 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 3 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.

Using the "split-half" method:
This is the reversed correlation between the chronological ranks and the scores of the test submissions. Higher numbers mean greater robustness, and a value of 1 means the scores are perfectly stable over time. This statistic is experimental, and its interpretation will have to be learnt by comparing it across statistical reports of different tests.
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.
Most of this report was generated by software created 2002-present by Paul Cooijmans.
