Independent and Dependent Variables of The Role of Nudging Techniques on the Customisation and Usability of Visual Analytics Dashboards

<p dir="ltr">A study on the impact of nudging techniques on customisation and usability in visual analytics dashboards:</p><ol><li>Encouraging engagement with customisation functionalities,</li><li>Enhancing decision-making through social comparison and just-in-time prompts,</li><li>Reducing completion time with usability-focused nudges,</li><li>Addressing mismatches in graph literacy among users.</li></ol><p dir="ltr">Participants interacted with dashboards featuring different nudging techniques.

The experiment aimed to understand how nudges affect user behaviour and usability outcomes.</p><p dir="ltr"><b>File 1 (independent and dependent variables):</b><br>50 participants completed the experiment. For each user, we have data on graph literacy level, effectiveness (correctness of answers), efficiency (task completion time in mm:ss), perceived performance, cognitive load, and engagement with customisation functionalities.</p><p dir="ltr"><br></p><p dir="ltr"><b>File 2 (interaction data):</b><br>This file contains click interaction data collected from 50 participants as they interacted with customisation functionalities in the dashboards under different nudging conditions.</p>
