Test of Inductive Reasoning / J.C.T.I. (Xavier Jouve) statistics

Paul Cooijmans

Introduction

These are statistics based on the scores on the Test of Inductive Reasoning and J.C.T.I. by Xavier Jouve as reported by test candidates of I.Q. Tests for the High Range. Please keep the following in mind: As a result of candidates' tendency to report their higher scores while withholding lower ones, there may be an upward bias in the reported scores, while the possible correlation with other variables is reduced as a result of the restriction of range inherent to this incomplete reporting.

Estimated g factor loadings upward and downward of particular scores

In parentheses the number of score pairs on which that estimated g factor loading is based. The goal of this is to verify the hypothesis that g becomes less important, accounts for a smaller proportion of the variance, at higher I.Q. levels. The mere fact of restricting the range like this also depresses the g loading compared to computing it over the test's full range, so it would be normal for both values to be lower than the test's full-range g loading.
