Cards in this group · 5
- U1.01.1Visual channels have a stable empirical accuracy ranking
- U1.01.2The ranking comes from magnitude-judgment experiments, not design intuition
- U1.01.3Quantitative and categorical data need two different channel rankings
- U1.01.4The most important variable should get the highest-ranked available channel
- U1.01.5The ranking is an accuracy ceiling; alignment and mark size erode it
