Explaining Uncertainty on Energy Overviews
The ongoing project compares three presentation variants intended to make measured values, estimates, scenarios, value ranges and data gaps distinguishable on energy overviews.
Problem
Point values make differences between measurement, estimate and scenario disappear. Readers can then no longer tell how reliable a figure is.
Research question
How can value ranges and data gaps be made distinguishable in a compact overview? The presentation should separate data types without overloading the overview.
Method
Three presentation variants are developed with synthetic data, together with a task-based test plan. At first, only a structured walkthrough is carried out.
Evaluation criteria
The planned assessment covers the correct distinction of data types, legibility and the quality of reasoned decisions. No usage evaluation has been carried out so far.
Expected outcome
Design rules together with their limits are expected. They are no evidence of actual user performance. The project is ongoing; results are outstanding.
Limits
The project offers no consumer advice and conducts no real usage study.
