Note. AOAA = all other items as anchors; 1-7 anchor(s) = one through seven items with the lowest X2 values are used as anchor items; STDS = signed test difference in the sample; UTDS = unsigned test difference in the sample; UETSDS = unsigned expected test score difference in sample; ETSSD = expected test score standardized difference.
