PSI VisSIG Wonderful Wednesday 13: Missing data

10 March 2021

Steve Mallet leads the discussion on ways to display data that is actually missing. The example data was based on a study with multiple measurements of pain that were partially incomplete. The presented visualisations can help to describe the amount, the nature and the impact of missing data on the study outcome. The mirrored histogram highlighted the difference in missing data in specific subgroups. In the Sankey diagram it is possible to see the missing data linked to the actual outcome pain. The course of pain over time is nicely shown in an animated scatter plot. For exploration of the complete data a complex lasagna plot surrounded with additional graphs gives insight. And a powerful tool to actually guide the reader though the data is scrolly-telling. All visualisation are available on the Wonderful Wednesday blog.

There was a wide range of visualisations presented serving very different purposes. A simple heat map focusses on the amount of missing data in the different treatment arms. The next challenge is about mobile app data. How does individual app usage change over time? And how does app usage impact individual outcomes?
