Previous research on the scaled-score range and the number of deviant subtest scores on the WISC-R and the WPPSI has produced surprising results: Normal children exhibited much more scatter than most clinicians probably realized. Yet, in principle, these results were predictable from a knowledge of the statistical properties of scaled scores. Procedures for evaluating the abnormality of the two indices of scatter are presented and their accuracy checked against the actual distributions of the indices for the two standardization samples. The findings suggest that the procedures are sufficiently accurate for most clinical applications, which supports their use when the actual distributions of the indices are unknown.
先前针对韦氏儿童智力量表修订版（WISC-R）和韦氏学前及初小儿童智力量表（WPPSI）的量表分数范围以及异常子测验分数数量所做的研究产生了惊人的结果：正常儿童所表现出的离散程度比大多数临床医生可能意识到的要大得多。然而，原则上，从对量表分数统计特性的了解来看，这些结果是可预测的。本文介绍了评估两种离散程度指标异常性的程序，并根据两个标准化样本中这些指标的实际分布情况检验了其准确性。研究结果表明，这些程序对于大多数临床应用来说足够准确，这支持了在指标实际分布情况未知时使用它们。
