A researcher was interested in whether head worn displays were better than tablet displays for assisting rst responders with their tasks. He had 17 paramedics use either a head worn display (n = 9) or a tablet display (n = 8) during a simulated medical emergency. Each paramedic’s subjective workload score was measured out of 20 (where 20 indicated the highest workload). The data did not conform to the assumptions of a parametric test. a.
