Many in the data visualization and evaluation communities recommend conveying the message or takeaway of the visualization in the visualization's title. This study tested that recommendation by examining how informative or generic titles impact a visualization’s visual efficiency, aesthetics, credibility, and the perceived effectiveness of the hypothetical program examined. Furthermore, this study tested how simple or complex graphs, and positive, negative, or mixed results (i.e., valence of the results) affected outcomes. Participants were randomly assigned to one of 12 conditions, representing a 2 (graph: simple or complex) x 2 (title: generic or informative) x 3 (valence: positive, negative, mixed) between-subjects study. The results indicated that informative titles required less mental effort and were viewed as more aesthetically pleasing, but otherwise did not lead to greater accuracy, credibility, or perceived effectiveness. Furthermore, titles did not interact with graph type or the valence of the findings. While the results suggest it is worthwhile to consider adding an informative title to data visualizations as they can reduce mental effort for the viewer, the intended goal of the visualization should be taken into consideration. Considering the goal of the visualization can be a deciding factor of the type of graph and title that will best serve its intended purposes. Overall, this suggests that data visualization recommendations that impact evaluation reporting practices should be scrutinized more closely through research.

数据可视化和评估社区中的许多人建议在可视化的标题中传达可视化的信息或要点。本研究通过检查信息性或通用标题如何影响可视化的视觉效率、美感、可信度以及所检查的假设程序的感知有效性来测试该建议。此外，这项研究测试了简单或复杂的图表，以及正面、负面或混合的结果（即结果的效价）如何影响结果。参与者被随机分配到 12 个条件之一，代表 2（图表：简单或复杂）x 2（标题：通用或信息性）x 3（效价：阳性、阴性、混合）受试者间研究。结果表明，信息丰富的标题需要较少的脑力劳动，并且被认为更美观，但除此之外并没有导致更高的准确性、可信度或感知有效性。此外，标题不与图表类型或调查结果的效价相互作用。虽然结果表明值得考虑为数据可视化添加信息标题，因为它们可以减少查看者的脑力劳动，但应考虑可视化的预期目标。考虑可视化的目标可能是最能满足其预期目的的图形和标题类型的决定因素。总的来说，这表明应该通过研究更仔细地审查影响评估报告实践的数据可视化建议。标题与图表类型或调查结果的效价无关。虽然结果表明值得考虑为数据可视化添加信息标题，因为它们可以减少查看者的脑力劳动，但应考虑可视化的预期目标。考虑可视化的目标可能是最能满足其预期目的的图形和标题类型的决定因素。总的来说，这表明应该通过研究更仔细地审查影响评估报告实践的数据可视化建议。标题与图表类型或调查结果的效价无关。虽然结果表明值得考虑为数据可视化添加信息标题，因为它们可以减少查看者的脑力劳动，但应考虑可视化的预期目标。考虑可视化的目标可能是最能满足其预期目的的图形和标题类型的决定因素。总的来说，这表明应该通过研究更仔细地审查影响评估报告实践的数据可视化建议。考虑可视化的目标可能是最能满足其预期目的的图形和标题类型的决定因素。总的来说，这表明应该通过研究更仔细地审查影响评估报告实践的数据可视化建议。考虑可视化的目标可能是最能满足其预期目的的图形和标题类型的决定因素。总的来说，这表明应该通过研究更仔细地审查影响评估报告实践的数据可视化建议。
