1 ?测验等值化 ... 测验数据 test data 测验难度 test difficulty 测验等值化 test equating ... 2 ?测验等值 测验等值(Test equating)就是将测量同一种特质的不同测验上的分数或项目参数作出单位系统的转换,从而使之能相互比较的过程[2-3].
- 1
The kernel method of test equating has five steps, including presmoothing, estimation of test score probability, continuation, equating and calculation of standard error of equating. 一般说来，核等值法有五个步骤，分别是前平滑处理、估计分数概率、连续化、等值、计算等值标准误。 - 2
To compensate for these variations, a statistical procedure known as "equating" is used to account for differences in test difficulty. 为了对以上的变化做出补偿，我们便采取了一个称为“等同”的统计学步骤，以考虑到不同考试的难易差异。 - 3
In large scale standardized tests, the test scores, before release, have to undergo a series of transformation processes, including score weighting, score equating, and score normalization, etc. 为了使分数带有大量信息，便于用户使用，大规模标准化考试在最终报道考试成绩前，分数要经过加权处理、等值处理、正态化转换等一系列转换过程。
