EDI-3 has T-scores for the three subscales and their composites and these are calculated using an analytical technique that removes any form of irregularities (Cumella, 2006). For the composite scores, the T-scores are summed up and transferred to percentiles. The EDI-3 profile sheet as well as the appendix play a critical role in charting T-scores and
