众所周知，学生对教学的评价与预期课程成绩呈正相关。作者确定了另外 4 种数据模式，这些模式共同区分了 5 种等级-评分相关性理论。学生评分数据（在华盛顿大学获得）中所有这 4 个标记的存在与以下理论最为一致：成绩与评分之间的相关性是由于教师评分宽松对评分造成的不良影响造成的。这一结论证明了使用统计修正（此处用实际评级数据进行说明）的合理性，以消除宽松评级所产生的不必要的评级膨胀。额外的研究可以有利地寻求对评级的其他不当影响，以确定更多增强有效性调整的机会。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）
It is well established that students' evaluative ratings of instruction correlate positively with expected course grades. The authors identify 4 additional data patterns that, collectively, discriminate among 5 theories of the grades-ratings correlation. The presence of all 4 of these markers in student ratings data (obtained at University of Washington) was most consistent with the theory that the grades-ratings correlation is due to an unwanted influence of instructors' grading leniency on ratings. This conclusion justifies use of a statistical correction—illustrated here with actual ratings data—to remove the unwanted inflation of ratings produced by lenient grading. Additional research can profitably seek other inappropriate influences on ratings to identify more opportunities for validity-enhancing adjustments.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
