如何在不同的理解水平上评估数据可视化

How to evaluate data visualizations across different levels of understanding

摘要:

理解可视化是一个多层次的过程。读者必须从数字事实中提取和推断,理解这些事实如何应用于数据的上下文和其他潜在的上下文,并从数据中得出或评估结论。一个设计良好的可视化应该支持这些层次的理解。我们诊断的可视化数据的理解水平,适应布卢姆的分类法,一个共同的框架,从教育文献。我们描述了框架的每个层次,并提供了如何将其应用于评估数据可视化的有效性的例子,沿着六个层次的知识获取-知识,理解,应用,分析,综合和评估。我们提出了三个案例研究表明,这个框架扩展了现有的方法,以全面衡量可视化设计如何促进观众的理解可视化。虽然布卢姆的原始分类法表明,一个强大的层次结构,为某些领域,我们发现几个例子,依赖关系的性能在不同的水平,我们的三个案例研究。如果这种水平独立性在新的测试可视化中保持不变,那么分类法可以激发对与沟通目标相关的理解水平进行更有针对性的评估。

英文摘要:

Understanding a visualization is a multi-level process. A reader must extract and extrapolate from numeric facts, understand how those facts apply to both the context of the data and other potential contexts, and draw or evaluate conclusions from the data. A well-designed visualization should support each of these levels of understanding. We diagnose levels of understanding of visualized data by adapting Bloom's taxonomy, a common framework from the education literature. We describe each level of the framework and provide examples for how it can be applied to evaluate the efficacy of data visualizations along six levels of knowledge acquisition - knowledge, comprehension, application, analysis, synthesis, and evaluation. We present three case studies showing that this framework expands on existing methods to comprehensively measure how a visualization design facilitates a viewer's understanding of visualizations. Although Bloom's original taxonomy suggests a strong hierarchical structure for some domains, we found few examples of dependent relationships between performance at different levels for our three case studies. If this level-independence holds across new tested visualizations, the taxonomy could serve to inspire more targeted evaluations of levels of understanding that are relevant to a communication goal.
