关于实例驱动建模技术的可行性
Concerning the Feasibility of Example-driven Modelling Techniques
摘要：
我们报告了一系列的实验，例如驱动建模的可行性。主要目的是在学术环境中建立实验：错误和任务复杂性之间的关系，使用a）传统的电子表格建模; b）示例驱动技术。我们报告的实验设计，抽样，研究方法和控制和治疗组的任务。对完成的任务进行分析可以比较几个不同的变量。实验结果通过比较准确性、经验、训练、置信度、感知难度和感知完整性来比较治疗组和对照组的性能指标。使用卡方检验、Fisher精确显著性检验、Cochran Q检验和McNemar难度检验彻底检验各种结果的统计显著性。
英文摘要：
We report on a series of experiments concerning the feasibility of example driven modelling. The main aim was to establish experimentally within an academic environment: the relationship between error and task complexity using a) Traditional spreadsheet modelling; b) example driven techniques. We report on the experimental design, sampling, research methods and the tasks set for both control and treatment groups. Analysis of the completed tasks allows comparison of several different variables. The experimental results compare the performance indicators for the treatment and control groups by comparing accuracy, experience, training, confidence measures, perceived difficulty and perceived completeness. The various results are thoroughly tested for statistical significance using: the Chi squared test, Fisher's exact test for significance, Cochran's Q test and McNemar's test on difficulty.
