Data gaps should not be shown as zero values

Erlangen. The project Explaining uncertainty on energy overviews starts from the observation that single values hide the difference between a measured value, an estimate and a scenario. Data gaps are particularly delicate, because on an overview they easily look like a value of zero.

The interim report Showing data gaps and value ranges describes three display variants using synthetic data. A task-based test plan is intended to look at the correct distinction between data types, legibility and the quality of reasoned decisions. For now, only a structured walkthrough is foreseen.

There are no results from a user study. The interim report is a document; its full text is planned as an HTML reading text and is not scientific evidence.
