Values in parentheses are SD of the Z scores or scaled scores. Superscripts indicate significantly different from published norms.
↵2-150 p<0.05;
↵2-160 p<0.01;
↵2-165 p<0.001, lower than the norm.
↵2-151 p<0.03, above the norm. For tests with published norms and scoring in percentile ranges rather than Z scores, a standard conversion table was used to convert percentile scores to Z scores (obtained score minus mean for normal subjects/SD for normal subjects, assuming a normal distribution for the normal subjects).
