T-score means, standard deviations and T-scores by percentile are computed for the full calibration sample to describe this sample. The normative sample from which the T-scores were derived was based on a subsample of the full calibration sample matched to U.S. census demographics. Therefore, the means and SDs for the full sample are not 50 and 10 respectively, and the values reported for the full calibration sample should not be used as norms (see Liu et al, this issue)
