This manuscript focusing on Pick-N items is the second of two manuscripts regarding scoring approaches of two specific multiple-select item types commonly used to assess knowledge in written examinations. In contrast to other multiple-select item types, the number of true answer options to be marked within each Pick-N item is disclosed to examinees. As various scoring methods for Pick-N items exist, the present study aimed to help educators make informed choices about the use of Pick-N items, the scoring method to be selected, and related aspects (i.e. defining appropriate examination pass marks). Available scoring methods for conventional multiple-select items and Pick-N items were systematically identified from the literature. Their statistical parameters were compared by assessing the metrics available information included and expected chance scores from random guessing. The study further aimed to examine the relation between examinees’ true knowledge and expected scoring results when using Pick-N items.

这份专注于 Pick-N 项目的手稿是两篇手稿中的第二篇，这些手稿涉及两种特定的多选题类型的评分方法，通常用于评估笔试中的知识。与其他多项选择项目类型相比，每个 Pick-N 项目中要标记的正确答案选项的数量会向考生公开。由于 Pick-N 项目的评分方法多种多样，本研究旨在帮助教育工作者对 Pick-N 项目的使用、要选择的评分方法和相关方面（即定义适当的考试及格分数）做出明智的选择。从文献中系统地确定了常规多项选择项目和 Pick-N 项目的可用评分方法。通过评估指标来比较他们的统计参数包括可用信息和随机猜测的预期机会得分。该研究进一步旨在检验考生在使用 Pick-N 项目时的真实知识与预期得分结果之间的关系。
