摘要
通过对测验等值方法和等值设计进行研究，得到改进后的线性等值公式．该公式不仅与两份测验的相关系数有关，而且同两份测验的信度有关，常用线性等值公式是其当两份测验信度相等时的一个特例．文中还给出了预报值的置信区间估计，同时提出一种新的等值设计方法：试卷分半组合的单组设计法．
In this paper equating methods and equating designs about test equating were reseached. The improved linear equating was proposed, this equation is depended on correlation coefficient of two test and depended upon reliability of the test, linear equating which was used before is a particular example when reliabilities of two test are same. The confidence interval estimae of predicted value was given, at the same time, a new equating design was proposed: Single group design about the test was composed of half of a tes and half of another test.
