等效分数（ES; Capitani Br Laiacona，1988）是一个5点量表，它提供了一个解决问题的标准化神经心理评分后，调整年龄和教育，鉴于常见的z标准化是不适用于这些情况。ES进行了讨论，并比较其性质和限制与z-标准化。在ES标准化测试的电池中，整个电池的平均ES（AES）可以提供整体认知水平的测量，不受年龄和教育的影响。我们报告的经验数据从电池组成的10 ES标准化测试，以讨论一般属性ES标准化。AES的预期平均值是恒定的，无论包含的测试数量或类型如何。然而，AES的标准差是可变的：它与测试的数量成比例地减小，但与它们的相互关联成比例地增大。我们提供了关于正态性阈值的一般指示，适用于ES标准化测试的所有电池，无论数量和类型如何。
Equivalent Scores (ES; Capitani Br Laiacona, 1988) is a 5-point scale that offers a solution to the problem of standardizing neuropsychological scores after adjustment for age and education, given that the common z-standardization is not generally applicable in these cases. ES are discussed, and their properties and limits are compared with those of z-standardization. In a battery of ES-standardized tests, the average ES (AES) for the whole battery can provide a measure of the overall cognitive level, free of the influence of age and education. We report empirical data from a battery composed of 10 ES-standardized tests, in order to discuss general properties of ES standardization. The expected mean of the AES is constant, regardless of the number or type of tests included. The standard deviation of the AES, however, is variable: it decreases in proportion to the number of tests, but increases in proportion to their intercorrelation. We provide general indications concerning the normality threshold, which are applicable to all batteries of ES-standardized tests regardless of the number and type.
