Abstract

The statistical consultant described in this paper incorporates a knowledge base in an educational tool for novices in statistical decision-making to use in choosing a statistical technique. The heart of the system is the rule base for differentiating between statistics. The rules are based on five questions which the data can answer, as well as the type of data, the number of variables, and any dependent/independent relationships which exist between the variables. Twenty-nine statistics and the rules for choosing them are in the rule sets. The consultant was tested against the usual textbook method with two different groups of users, 25 undergraduates and 19 doctoral students. The results were that the computer-assisted students in both samples correctly solved a larger proportion of problems despite a conservative test which favored the textbook users and also took longer to find an appropriate solution.<>

帮助学生解决统计问题的顾问

本文中描述的统计顾问在一个教育工具中纳入了一个知识库，供统计决策新手在选择统计技术时使用。系统的核心是区分统计数据的规则库。这些规则基于数据可以回答的五个问题，以及数据的类型、变量的数量和变量之间存在的任何依赖/独立关系。29个统计数据和选择它们的规则都在规则集中。该咨询师在两组不同的用户(25名本科生和19名博士生)中接受了常规教科书方法的测试。结果是，在这两个样本中，计算机辅助的学生正确解决了更大比例的问题，尽管保守的测试倾向于教科书使用者，而且需要更长的时间才能找到合适的解决方案。
