  1. Note. The reported values are for raw scores unpartialled for sex, age, or g. The Study Two sample scored significantly higher than the Study One sample on Wiggly Block, Paper Folding, Number Facility, Number Memory, and Analytical Reasoning (p < .05). The two groups did not differ significantly on any of the interest measures except for Conventional, on which the Study Two sample scored about .4 of a standard deviation higher than the Study One sample.
