A dissolution of simply one standard error of the difference would simply fail me 68% confidence that the two scores are different. As a result of the workings on a lower floor I can be, 95% confident that the two scores (verbal comprehension) and (perceptual reasoning) differing by 2?diff (10.8) check true score differences.
