Correlation with other tests:

Mean correlation: 0.38

Used for norming are all that correlate .74 or higher. Prior scores are converted to the same scale (SD=15) if needed. Raw and prior scores are put in columns of numerical order, the highest facing the highest etc. Each raw score is normed at the median of the IQ's facing it. Scores above 28 are extrapolated. [March 2008 the IQ norms were converted to protonorms using the initial protonorm formula.]

Correlation with other tests

Weighted average of correlations: 0.474

Conservatively estimated minimum g loading: 0.69

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.

National averages

For reasons of privacy, only countries with 2 or more candidates are included in this table. Ranking is based on the unrounded averages.

Correlation with personal details

Correlation with personal details - within females

Correlation with national IQs

Correlation of this test with national average IQs published by Lynn and Vanhanen:

• r = 0.18
• n = 90

Reliability and standard error

Using the "split-half" method:

• Rel = 0.85
• SE = 2.1 raw score points

Scores by age

Scores by age - within females

Scores by year taken

Correlation year taken vs average score = 0.46
n = 107

Robustness and overall test quality

• Rob = 0.54
• Quality = 0.70

Item analysis

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 (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.
