提出了一个测量两个分数之间差异的模型，并讨论了它作为研究成长或实验产生的变化的范例。该模型假设了两个复杂程度不同的测试或测量，并将测试分数之间的真正差异分析为一个完全依赖于第一个或基线测试的组成部分和一个完全独立于它的第二个组成部分。给出了估计这两个分量的公式，并将这些公式与具有类似目标的其他测量工作进行了比较。
A model for the measurement of the discrepancy between two scores is presented and discussed as a paradigm for the study of growth or experimentally produced change. The model assumes two tests or measures differing in complexity, and it analyzes the true difference between the test scores into a component that is entirely dependent on the first or base‐line test and a second component that is entirely independent of it. Equations for estimating both components are given and these are compared with other measurement efforts with similar goals.
