The graph shows a bar chart comparing task completion times for blind users and for a control group when using low accessibility and high accessibility web sites. The scores have been set to a baseline of 100 and lower scores are better (i.e. low scores mean people could complete their tasks more quickly). The control group's task completion time was 100 for high accessibility web sites and 146 for low accessibility web sites. Blind users task completion time was 321 for high accessibility web sites and 486 for low accessibility web sites. Data plotted from the DRC's report, Formal Investigation Report: Web Accessibility.
