测量与预测数据可视化问题难度的变异

Measuring and predicting variation in the difficulty of questions about data visualizations

Arnav Verma, Judith E. Fan

AI总结:

通过对503名美国成年人施测五项数据可视化素养测试的综合测验,发现题目难度估计高度可靠,但可视化与任务类型仅能解释适中变异,需更细粒度特征预测并推广难度差异。

摘要:

理解数据可视化所传达的信息,是现代科学素养的关键组成部分。然而,为何某些涉及数据可视化的任务比其他任务更困难,目前仍不清楚。在此,我们对大量美国成年人样本(N=503名参与者)施测了一项综合测试,该测试由五种广泛使用的数据可视化素养测试组成。我们发现,综合测试中的题目覆盖了所有可能的难度水平,而且我们对题目层面难度的估计具有高度可靠性。但是,相对于我们所获得估计值的可靠性,所展示的数据可视化类型以及所涉及的任务类型,只能解释不同题目间表现变异的适中部分。这些结果凸显出,需要更细粒度的方法来刻画这些题目,以预测本研究中测得的可靠难度变异,并将其推广到其他数据可视化理解测试。

英文摘要:

Understanding what is communicated by data visualizations is a critical component of scientific literacy in the modern era. However, it remains unclear why some tasks involving data visualizations are more difficult than others. Here we administered a composite test composed of five widely used tests of data visualization literacy to a large sample of U.S. adults (N=503 participants).We found that items in the composite test spanned the full range of possible difficulty levels, and that our estimates of item-level difficulty were highly reliable. However, the type of data visualization shown and the type of task involved only explained a modest amount of variation in performance across items, relative to the reliability of the estimates we obtained. These results highlight the need for finer-grained ways of characterizing these items that predict the reliable variation in difficulty measured in this study, and that generalize to other tests of data visualization understanding.
