Abstract:
The purpose of this study was to verify the finding of the authors of the Repetitive Psychometric Measures that the twenty forms of the Number Facility NF and Speed of Closure SC sub-tests were not of equivalent difficulty. Twenty subjects were given twenty forms of the NF and SC and twenty additional trials on reconstructed forms of the NF. The relative level of difficulty for forms from our samples correlated significantly with the sample of the authors of the test for the SC, but not for the NF. The reconstructed forms of the NF were not more equivalent than the original forms. Practical implications of these findings for the use of these sub-tests were discussed. Author
